39 CFR Part 121


Service Standards for Market-Dominant Mail Products

AGENCY: Postal ServiceTM.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The United States Postal Service is revising the service 
standards for certain market-dominant services, specifically First-
Class Mail[supreg], Periodicals, USPS Marketing Mail, and Package 
Services. The new service standards, which will be implemented in two 
phases, align with operational initiatives that the Postal Service 
plans to implement on a nationwide basis to fundamentally transform its 
processing and transportation networks to achieve greater operational 
precision and efficiency, significantly reduce costs, and enhance 
service pursuant to the Delivering for America strategic plan. The 
changes will maintain service at existing levels for most volume, will 
upgrade standards for more market-dominant volume than is downgraded, 
and will improve service reliability.

DATES: Effective April 1, 2025, except for instruction 4 (revising part 
121), which is effective July 1, 2025.

I. Introduction

    By adopting this final rule, the Postal Service is amending 39 CFR 
part 121 to revise the current service standards for certain market-
dominant products. The Postal Service is restructuring the service 
standards for domestic First-Class Mail, such that the service 
standards will retain the current day range of 1-5 days (as well as the 
current 0-1 days for USPS Connect[supreg] Local), while being 
calculated, with certain exceptions, as the sum of delivery days 
accruing across three successive operational legs reflecting end-to-end 
service from an originating 5-digit ZIP Code to a destinating 5-digit 
ZIP Code. The rule also partially adjusts the service standards for 
end-to-end Periodicals, USPS Marketing Mail, and Package Services so 
that they will be primarily based on the standards for First-Class 
Mail, consistent with the Postal Service's implementation of a more 
integrated network, thus continuing efforts to eliminate the Postal 
Service's legacy network that, due to its poor design, has multiple, 
redundant network flows.
    These revisions achieve the objectives set forth in 39 U.S.C. 
3691(b), taking into account the factors of 39 U.S.C. 3691(c). Overall, 
they further the Postal Service's obligations under 39 U.S.C. 101 and 
other provisions of Title 39 of the U.S. Code to provide universal 
postal services in a prompt, reliable, and efficient manner. The Postal 
Service is required by law to provide universal postal services in a 
financially self-sufficient manner, through an integrated network for 
the delivery of mail and packages at least six days a week. Currently, 
the Postal Service is not financially self-sufficient and lacks a 
network that is conducive to the logical, efficient, cost-effective, 
and reliable movement of mail and packages in an integrated manner from 
origin to destination in the modern postal environment, taking into 
account the current and projected volume, revenue, costs, and product 
mix. The Postal Service network has not been appropriately adjusted to 
account for volume, revenue, costs, and mail mix changes, including the 
substantial decline in Single-Piece First-Class Mail volume and 
increase in package volume, leading to significant inefficiencies.
    The new service standards align with operational initiatives that 
the Postal Service plans to implement on a nationwide basis to 
fundamentally transform its processing and transportation networks to 
achieve greater operational precision and efficiency, significantly 
reduce costs, and enhance service pursuant to the Postal Service's 
Delivering for America strategic plan (DFA Plan). These initiatives 
will comprehensively transform the Postal Service's operations to 
address problems that exist today and create a network that enables the 
integrated movement of mail and packages in a precise and cost-
effective manner consistent with best business practice far into the 
future. They should also lead to substantial cost savings 
(conservatively estimated at between $3.6 to $3.7 billion annually), 
which is critical given the Postal Service's current poor financial 
condition, which can be addressed only through comprehensive changes to 
reduce costs and increase efficiency (in conjunction with the other 
elements of the DFA Plan).
    To illustrate, the current service standards require the Postal 
Service to conduct separate trips to drop off destinating volume from 
the processing network to collection/delivery facilities in the morning 
for delivery that day, and then pick-up originating volume from the 
collection/delivery facilities to the processing network in the 
afternoon, or alternatively pay Highway Contract Route contractors to 
layover for multiple hours between the outbound and return legs of 
their routes. Many of these trips transport low amounts of volume to 
and from collection/delivery facilities that are far from the Postal 
Service's processing facilities. The Postal Service's Regional 
Transportation Optimization (RTO) initiative will eliminate some of the 
costs and inefficiencies associated with these excess trips by allowing 
certain mail and packages to be picked up the next day from the Post 
Office on the same trip that also dropped off mail at that Post Office 
for delivery that day. The

[[Page 10858]]

Postal Service will designate 5-digit ZIP Codes for RTO when a retail/
collection facility servicing that 5-digit ZIP Code is more than 50 
miles from the originating Regional Processing and Distribution Center 
or Campus (RPDC), though exceptions may apply based on operational or 
business considerations. Under the new service standards, which are 
needed to implement RTO, most mail and packages would either receive 
the same service standard or an accelerated standard so that it is 
delivered faster than today, while some mail and packages would have a 
service expectation that is one day longer than the current expectation 
but still within the current day-ranges. Further details of the changes 
appear below.
    By implementing the new standards and the operational initiatives 
to which they are aligned, the Postal Service will be better able to 
achieve the goals of the DFA Plan to create a high-performing, 
financially sustainable organization, which is necessary for the Postal 
Service to achieve the statutory policies and objectives adopted by 
Congress.
    The Postal Service will implement the final rule in two phases, 
with phase 1 going into effect on April 1, 2025, and phase 2 going into 
effect on July 1, 2025. As described further below, during phase 1, the 
Postal Service will enable the implementation of RTO by adding one 
service expectation day to certain volume in Leg 1 (i.e., from 
collection to originating processing facility) for items originating in 
ZIP Codes covered by RTO. On July 1, during phase 2, the Postal Service 
will implement the proposed rule in its entirety and will therefore 
among other changes accelerate the movement of mail in Leg 2 (i.e., 
from originating processing facility to destinating processing 
facility) by expanding the drive times for each of the travel bands 
that establish the delivery expectation days for First-Class Mail by 
four hours. Phase 2 is dependent upon certain efficiencies gained as a 
result of RTO and requires significant changes across the Postal 
Service's processing, logistics, and delivery networks. By delaying the 
service standard changes related to Leg 2 for a brief period of 90 
days, the Postal Service will be able to facilitate effective 
operational execution and change management by gradually implementing 
these changes, reducing the immediate impact on front-line employees 
and decreasing the level of change that is implemented at one time. In 
addition, during the 90-day period between phase 1 and phase 2, the 
Postal Service will gather data on real-world operational conditions 
and constraints arising from RTO and use this data to adjust 
operational planning regarding Leg 2 operations to the extent 
warranted, and therefore help ensure that the Postal Service is well 
positioned to implement the Leg 2 service standard changes. To be 
clear, the phased approach is to facilitate more effective 
implementation of the changes. The rule, as originally proposed and as 
repeated below, will be implemented in full on July 1.
    On October 4, 2024, the Postal Service requested from the Postal 
Regulatory Commission (PRC or Commission) an advisory opinion on the 
service standard changes, including those described herein, for market-
dominant and competitive products, together with a comprehensive 
strategy of network modernization, in accordance with 39 U.S.C. 
3661(b). The PRC then initiated Docket No. N2024-1, in which the PRC's 
Presiding Officer, its appointed Public Representative, and a number of 
intervenors actively participated, including issuing extensive 
discovery requests. The PRC also conducted a formal hearing with 
testimony on the record. The Postal Service's proffered evidence 
demonstrates significant benefits to implementing these operational 
initiatives and corresponding service standards consistent with the 
policies enumerated in Title 39 of the United States Code: the same or 
accelerated standards for a majority of market-dominant volume within 
the current day ranges; user-friendly service standards formulated at 
the 5-digit Zip Code level; significant cost savings from productivity 
enhancements, consolidated local transportation trips, streamlined 
transportation between facilities within the redesigned network, an air 
network reoriented around RPDCs, lease terminations, and facility 
closures, all of which are critically important to achieving long-term 
financial sustainability; and ultimately, more reliable, predictable, 
sustainable, and consistent service. The proceeding culminated in an 
advisory opinion issued by the PRC on January 31, 2024.
    The PRC's advisory opinion acknowledges the necessity of change, 
agreeing that the Postal Service must improve its financial standing, 
modernize its operations, and ensure the continuing provision of 
universal service. Of the specific changes proposed by the Postal 
Service, and whether they are consistent with the policies of the Title 
39 of the United States Code, the PRC declines to make a definitive 
statement. Yet the PRC is highly critical of the Postal Service's 
plans, faulting the Postal Service's network modeling and operational 
preparedness to implement the changes, minimizing the projected cost 
savings as being ``meager'' and hence not material to achieving 
financial sustainability, and voicing concern over impacts to rural 
customers, among other criticisms. The PRC therefore suggests that the 
Postal Service reconsider whether to implement this proposal. In lieu 
of a fair and comprehensive assessment, however, the PRC's advisory 
opinion presents a one-sided narrative that mischaracterizes the Postal 
Service's proposal, ignores the benefits it can be reasonably expected 
to yield, baselessly magnifies its alleged downsides, downplays the 
necessity of financial self-help, and makes unrealistic demands that 
would, if heeded, impede urgently needed progress.
    The Postal Service has responded in depth to the PRC's opinion and 
recommendations at https://about.usps.com/newsroom/national-releases/2025/0220-usps-responds-to-prc-advisory-opinion-on-service-standard-changes.htm. There, the Postal Service disputes the PRC's overall 
assessment of the proposed changes and rebuts the faulty reasoning, 
factual misapprehensions and tendentious arguments informing that 
assessment. The Postal Service also provides a response to each of the 
PRC's recommendations. This Notice cannot replicate, and is not 
intended to replace, that more substantive response. It is, however, 
appropriate to address at a high level of generality three topics 
emphasized by the PRC: the Postal Service's cost savings projections, 
the Postal Service's network modelling efforts, and the impacts of the 
Postal Service's plans on rural communities.
    The Postal Service conservatively estimates yearly savings of 
approximately $4 billion. As noted, the PRC dismisses this sum as a 
``meager'' reduction in overall expenses. Such criticisms betray a 
thorough-going lack of concern for the Postal Service's financial 
viability under the current business model. No entity in the private or 
public sector would disregard (much less forego) annual cost savings 
totaling in the billions. To avert service deterioration and 
insolvency, the Postal Service must become financially self-sustaining; 
to become financially self-sustaining, it must reduce costs within the 
constraints of its service mission--and this proposal will reduce costs 
by addressing clear deficiencies in the Postal Service's current 
network while also ensuring that all customers continue to receive 
prompt and reliable service.
    Despite the urgent need for meaningful change, the PRC would 
perpetuate the status quo by

[[Page 10859]]

recommending that before self-help initiatives are implemented, the 
Postal Service embark on a dilatory, burdensome, seemingly open-ended 
chain of ex ante ``modelling'' exercises that would add no discernible 
value. The Postal Service's plans are, in fact, based on robust 
deliberation and analysis, and are supported by industry-standard 
models, software, and analytical protocols. They also acknowledge 
certain basic realities: the Postal Service runs a highly complex 
organization, works within a vast embedded infrastructure, and must 
serve the American public even as it transforms its processing and 
transportation networks. The Postal Service has accordingly proposed a 
framework for network modernization, based on well-designed operating 
strategies and principles, which will be implemented through a 
systematic, iterative, region-by-region implementation approach that 
enables the Postal Service to address what is necessary to most 
efficiently transport and process mail and packages within each region, 
while also ensuring that the network as a whole is structured in a 
standardized, effective, and integrated manner. Though the PRC 
criticizes the Postal Service for its alleged overreliance on 
``business judgment,'' the need for pragmatic decision-making--informed 
by fact-gathering and operational expertise--will inevitably arise over 
the course of any complex endeavor, not excluding this one. As the 
Postal Service proceeds to implement its plans, responsiveness to on-
the-ground feedback will be beneficial; rigid adherence to all-
encompassing ``models'' that ignore complex and shifting realities will 
not.
    The changes that are the subject of this rulemaking retain or 
accelerate service standards for most market-dominant volume--a fact 
that garners little recognition from the PRC. Instead, the PRC accuses 
the Postal Service of not sufficiently considering the revised 
standards' impact on rural ZIP Codes. This is baseless: the Postal 
Service considered rural impacts in depth when designing this proposal 
and has thoroughly explained why it believes the balance that has been 
struck regarding the statutory policies is appropriate, given the 
operational benefits and overall impact on service. In this regard, the 
Postal Service considered the fact that (1) the changes would add one 
day within the existing service standard day ranges to the First-Class 
Mail service standards for mail originating in areas far from the 
processing network (with some very minor exceptions), which encompasses 
both rural and non-rural areas; (2) the current day ranges for First-
Class Mail would stay the same, and be shortened for other end-to-end 
mail products, (3) the changes would benefit the speed of service 
within Leg 2 overall (and hence would improve the delivery of mail to 
rural communities), and (4) the changes would improve service 
reliability overall. The PRC sidesteps the steep and irreversible 
declines in Single Piece First-Class Mail use--declines to which the 
proposed RTO initiative and accompanying ``Leg 1'' service standard 
changes respond. Nor does the PRC acknowledge a key fact about First-
Class Mail as a whole (i.e., including Presort First-Class Mail): 
namely, that customers receive on average far more mail than they send. 
In this regard, the revised standards provide inbound network benefits, 
with the same or upgraded service over an expanded area, for the 
critical goods and services that most customers, including rural 
customers, receive. The PRC also fails to recognize that local 
turnaround service from RPDCs and some LPCs will provide 2-3-day 
service standards for mail destined within the same service area. 
Ultimately, the Postal Service gave serious consideration to rural 
impacts, and with the service standard changes described below, has 
appropriately balanced its competing obligations under Title 39 of the 
United States Code.
    Despite the flaws in the PRC's analysis, the Postal Service agrees 
with many of the PRC's recommendations, many of which are already part 
of the planned implementation process or would otherwise occur in the 
course of business. Many of these recommendations concern building out 
the implementation plan and are generally consistent with the thorough 
planning, transparent customer communication, robust mitigation 
efforts, and swift execution adjustments that are at the core of the 
Postal Service's implementation strategy. The Postal Service will 
balance planning with continuous evaluation of performance during 
implementation and will improve processes and make broader adjustments 
as appropriate. Based on reasonable business judgement and experience, 
the Postal Service believes this is the best, and fastest, way to 
ensure successful implementation not only of the service standard 
change, but of the plan generally.
    The PRC also made several recommendations that were inextricably 
linked to its flawed analysis with which, as noted above, the Postal 
Service disagrees. To the extent that a recommendation is based on the 
PRC's flawed understanding of the Postal Service's proposal or the 
false premise that the Postal Service lacked highly rigorous methods or 
models when developing its proposal, the Postal Service disagrees. 
Finally, the Postal Service has thoroughly considered its obligations 
under title 39, including 39 U.S.C. 101(a) and (e), and has 
appropriately balanced the various statutory considerations and 
requirements, and therefore the Postal Service does not agree with the 
PRC's recommendation to reconsider those matters.

II. Comments

    On November 15, 2024, the Postal Service published proposed 
revisions to market-dominant service standards in the Federal Register 
and sought public comment (Proposed Rule). Service Standards for 
Market-Dominant Mail Products, 89 FR 90241 (Nov. 15, 2024). The comment 
period for the Proposed Rule closed on December 31, 2024. Although 
exempt from the document and comment requirements of the Administrative 
Procedure Act (5 U.S.C. 553(b), (c)) regarding rulemaking by 39 U.S.C. 
410(a), nonetheless the Postal Service requested comments on all 
aspects of the Proposed Rule. In particular, the Postal Service 
solicited comments on the effects that the Proposed Rule could have on 
senders and recipients of the affected market-dominant mail classes, as 
well as comments on the nature and extent of costs or savings they 
might experience as a result of the changes described in this document, 
and on any additional possible costs or benefits they foresaw, such as 
increased reliability and predictability. The Postal Service encouraged 
the provision of any empirical data supporting any cost-benefit 
analysis. The Postal Service further requested mail users' views 
regarding the application of the policies and requirements of Title 39 
of the U.S. Code, particularly sections 101, 403, 404, and 3691, to the 
Proposed Rule.
    The Postal Service received approximately 17,500 comments in 
response to the Proposed Rule. The vast majority (nearly all) of the 
comments received were form letters, which raised concerns that the 
proposed changes would slow down the delivery of critical items, such 
as bills, checks, and medicines.
    The Postal Service received only a few dozen comments that were not 
form letters, including a submission from a congressperson and a few 
comments from advocacy groups. Several such comments expressed concerns 
that the

[[Page 10860]]

changes would harm rural communities, vulnerable populations, and small 
businesses. Others objected to the use of cost-savings as a 
consideration when establishing service standards, and/or questioned 
whether the Postal Service's projected efficiencies and cost-savings 
are reliable. A number of residents of Wyoming and other states 
objected to the closure, perceived downgrading, and/or consolidation of 
processing facilities, as well as the processing of intrastate mail, 
including election mail, in other states.
    Several comments included complaints and opinions regarding matters 
unrelated to the proposed market-dominant service standard changes. 
Such topics include, but are not limited to, the privatization of the 
Postal Service, the tenure of the Postmaster General, past price 
increases, electric vehicles, and new business opportunities. The 
Postal Service is not responding to comments that fall outside the 
scope of this rulemaking. Separately, a number of individuals raised 
concerns that the changes would delay the delivery of medicines, 
merchandise, and other goods that are typically sent using competitive 
package services, including Priority Mail[supreg] and USPS Ground 
Advantage[supreg]. The impact on competitive products was addressed in 
the advisory opinion case described above, but is not addressed in this 
rulemaking, which impacts market-dominant products only.
    One comment submitted was a copy of a statement of position that 
had been filed in the PRC advisory opinion proceeding, re-submitted to 
the Postal Service as comments for this rulemaking. The Postal Service 
likewise incorporates by reference its Initial Brief and Reply Brief as 
filed publicly in the PRC proceeding. Initial Brief of the United 
States Postal Service, PRC Docket No. N2024-1 (December 18, 2024), 
https://prc.arkcase.com/portal/filings/134330; Reply Brief of the 
United States Postal Service, PRC Docket No. N2024-1 (December 26, 
2021), https://prc.arkcase.com/portal/filings/134602.
    The comments received and the Postal Service's responses thereto 
are addressed in greater detail below. With respect to individuals who 
doubted whether their comments would be read, the Postal Service indeed 
reviewed and considered each comment received.

III. Response to Comments

A. Service Impacts

    Most of the commenters noted that they are opposed to the revised 
service standards because they assert that the changes would 
significantly slow down the delivery of critical items, such as bills, 
checks, letters, medicines, election mail, business supplies, and other 
time-sensitive deliveries. Many of these individuals stated that their 
mail is already slower and less reliable, and they worried that the 
changes would further slow down delivery. A few individuals objected to 
the Proposed Rule based on a false understanding of the changes 
involved. For example, one person worried the changes would extend mail 
times ``by 1 day for every 50 miles from the new mail processing 
center,'' when in actuality the Proposed Rule adds one day at most to 
impacted mail (a very small amount of volume--approximately 1% of 
Single-Piece First Class Mail--would have two days added). As an 
additional example, one person thought Priority Mail would become a 7-
9-day service. Neither the Proposed Rule nor the Postal Service's 
broader DFA Plan will convert Priority Mail to a 7-9-day service. 
Several commenters feared that slower delivery speeds could cause 
people to lose trust in the Postal Service and/or turn to private 
carriers instead.
    In addition to general concerns about delivery speed, many comments 
noted that timely postal services are particularly important to rural 
communities, who may be unable to easily access public services due to 
their remote location. For example, one advocacy group objected to the 
plan because of the service standard impacts of the proposal on Single-
Piece First-Class Mail volume in rural areas. Similarly, some 
commenters noted that elderly and disabled populations may be 
particularly harmed by service delays, as such communities tend to rely 
heavily on postal services due to accessibility constraints. A few 
small business owners indicated that they use the Postal Service to 
obtain critical supplies, parts, and information, and/or to deliver 
goods to their customers. One such individual noted that his business 
often mails orders at the end of the day and so the elimination of 
afternoon pickup, could cause his shipments to be delayed, making it 
harder to compete with businesses that can offer faster delivery.
    Apart from concerns regarding the service standard changes, several 
people raised concerns regarding performance issues. Many people shared 
anecdotal stories of prior deliveries that were delayed, implying that 
the proposed changes will exacerbate performance failures. One 
customer, for example, claimed to have incurred overdue fees due to 
payments being delayed. Another individual questioned whether the 
Postal Service's decision to lower its performance targets for FY25 
means that the Postal Service ``is anticipating worsening service in 
the coming year once it resumes the rollout of these changes.'' This 
commenter further noted that certain locations where the Postal Service 
implemented its RPDC and Local Transportation Optimization (LTO) 
initiatives, including Richmond and Atlanta, experienced a decline in 
service performance, suggesting that similar declines could occur when 
the Postal Service rolls out further RPDCs and RTO.
    In addition to focusing on the proposed rulemaking, a few 
individuals claimed that the elimination of Sundays and holidays as 
transit days for measurement for mail and packages that enter the 
Postal Service's network on a Saturday or the day before a holiday 
would further delay mail deliveries.
    As an initial matter, these comments overstate the impact of the 
service standard changes on customers. In order to understand the 
impact, it is important to examine what is changing and how the changes 
will affect the various items customers send and receive. Under the 
Proposed Rule, one service expectation day will be added to certain 
volume in Leg 1 (i.e., from collection to originating processing 
facility) for items originating in ZIP Codes covered by RTO. However, 
RTO will remove the dependency between collections and transportation, 
thereby allowing the Postal Service to correct the significant 
deficiencies that currently exist in its local and regional 
transportation networks and enabling improved volume arrival profiles 
at processing facilities. As a result, the Postal Service will be able 
to accelerate the movement of mail in Leg 2 (i.e., from originating 
processing facility to destinating processing facility) by expanding 
the drive times for each of the travel bands that establish the 
delivery expectation days for First-Class Mail by four hours.
    The overall impact of these changes is that most market-dominant 
volume, including First-Class Mail, will have the same or better 
service standard than it does under the current standards and service 
overall will be more consistent and reliable. While certain Single 
Piece First-Class Mail items that are mailed by customers in a ZIP Code 
subject to RTO may have a service expectation that is one day longer 
than it is today, all First-Class Mail items will still fall within the 
existing 1-5-day service standard range (excluding USPS Connect[supreg] 
Local, which has a 0-1-day standard). Further, Single Piece First-Class 
Mail items originating and destinating within the same RPDC service 
area or the same Local Processing Center (LPC) service area for

[[Page 10861]]

qualifying LPCs (turnaround volume) will have a 2-3-day service 
standard. Items sent using Presort First-Class Mail and destination 
entry rates will not be impacted by RTO and should enjoy faster service 
in Leg 2. End-to-end Periodical pieces originating and destinating 
within the contiguous 48 states will have a 3-6-day service standard, 
which is overall faster than the current 3-9-day standard. End-to-end 
USPS Marketing Mail and Package Services originating and destinating 
within the contiguous 48 states will have a 4-7-day service standard 
instead of the current 3-10-day standard for USPS Marketing Mail and a 
2-8-day standard for Package Services.
    For further context, the volume of mail collected through the 
Postal Service's retail facilities (including mail collected on carrier 
routes and entered at Post Offices) has declined substantially in 
recent decades: for instance, in FY 1997 there were 57 billion pieces 
of Single-Piece First-Class Mail, which by FY 2023 had declined by 80 
percent to 12 billion pieces. Single-Piece First-Class Mail is also 
just one product among many. For example, in the fourth quarter of 
FY2024, Single-Piece First-Class Mail represented 26 percent of overall 
all First-Class Mail and 12 percent of all Market Dominant volume. 
However, the current service standards only take Leg 2 operations into 
account, and therefore have not been adjusted to reflect Leg 1 
operations even though the volume of Single-Piece First-Class Mail 
being handled in Leg 1 has declined precipitously. This means that the 
Postal Service is running a large number of transportation trips in Leg 
1 with largely empty trucks, adding limited value to service while also 
producing excess costs and carbon emissions, in order to meet the 
current service standards.
    Since letters, mail-in ballots, payments, and other letter-sized 
items that customers send are typically sent using Single Piece First-
Class Mail, most of these items will have a service standard that is 
the same or faster than the current standard, though some will have 
standard that is slightly longer, but all still within the current day 
ranges. Government checks and communications, utility bills, ballots, 
and other letter-sized items that customers receive are often sent 
using Presort First-Class Mail, which will not be impacted by RTO and 
may experience accelerated service in Leg 2 once phase 2 is 
implemented. Medicines, merchandise, and other goods are typically sent 
using competitive package services, and therefore, generally fall 
outside the scope of this rulemaking (though most packages will also 
receive the same or accelerated service under the new standards). In 
addition, since most customers receive more mail than they send and the 
majority of mail volume originates in locations that will not be 
subject to RTO, most customers will see the same or faster speeds, with 
improved service overall, regardless of where they live. Finally, 
service reliability will improve for all volume, as the Postal 
Service's transformed network will enable more precise operations.
    To be sure, these changes reflect a tradeoff with certain mail 
experiencing a slightly longer delivery time. However, as described 
elsewhere, given the steady and irreversible decline of Single Piece 
First-Class Mail, these changes are reasonable and appropriately 
tailored to achieve significant cost savings and improve operational 
efficiency and precision, which is critical if the Postal Service is to 
achieve its statutory obligation to be financially self-sufficient, all 
while maintaining service within the current service standard day 
ranges for most items. Indeed, a few commenters agreed with the Postal 
Service's decision to eliminate certain low-volume truck runs, and/or 
suggested that the Postal Service struck the right balance in expanding 
certain delivery standards by one day in order to avoid these 
inefficient trips.
    Further, comments regarding concerns about service performance, 
including concerns that the changes will exacerbate past failures, 
overlook that the service standard changes and related operational 
initiatives will result in service standards being more precise and 
reliable. The Postal Service's current First-Class Mail standards are 
predicated solely on plant-to-plant driving distances, meaning they are 
based on 3-digit to 3-digit ZIP Code pairs. The new standards are based 
on more precise 5-digit to 5-digit ZIP Code pairs, which more 
accurately and logically reflect the three operational legs applicable 
to the movement of mail and packages: collection to origin processing 
(Leg 1), origin processing to destination processing (Leg 2), and 
destination processing to delivery (Leg 3). This move will provide 
customers with more detailed and logical information about the service 
they can expect. In addition, performance failures are often largely 
due to the fact that the Postal Service's legacy network is ill-
designed to meet current market realities. The service standard changes 
and related operational initiatives are designed to create an 
efficient, reliable, and precise network, with achievable service 
standards that are appropriately aligned to that network. In other 
words, these changes are structured to address, not exacerbate, past 
performance issues.
    The concern that the Postal Service's performance targets for FY25 
reflect that the Postal Service is anticipating worsening service once 
RTO is implemented, ignores that the targets are higher than FY2024 
performance, so the targets say nothing of the sort. The targets 
reflect operational reality and the magnitude of the transformational 
task ahead of the Postal Service; they reflect the transitions which 
will unfold during the coming year, but in no way do they belie the 
improvements the Postal Service expects the modernized network to 
achieve over the long term. The Postal Service seeks to build a cost-
effective network in which its long-term service excellence goal can be 
achieved in a financially and operationally sustainable manner, in 
contrast to prioritizing higher short-term performance at the expense 
of building a cost-effective network. What the Postal Service learned 
from improved service performance in FY 2022, and again in FY 2023 
where service performance for several products reached 95 percent, was 
that achieving such a level of service performance within the existing 
network could only come at an unacceptable cost that the Postal Service 
is simply no longer able to bear, given its legal obligation to be 
financially self-sufficient.
    The Postal Service acknowledges that the implementation of some of 
the DFA Plan initiatives has led to temporary service performance 
issues in certain areas, due to issues with initial execution. The 
results initially seen in Atlanta and Richmond were unacceptable, and 
recovery in those initial regions took too long. Richmond was the first 
RPDC region, and Atlanta was a particularly complex activation that 
involved a brand-new facility and the consolidation of a large number 
of separate facilities. These issues were temporary, and the Postal 
Service has seen significant service improvements in those regions. In 
addition, other regions, such as Portland, did not experience a 
significant decrease in service performance when its RPDC was 
implemented. Finally, the Postal Service has and will continue to 
leverage the experience from these early implementations to subsequent 
RPDCs.
    Moreover, with respect to service performance at the LTO pilot 
locations, the Postal Service utilized the pilots to assess the 
operational and service implications of the initiative and to determine 
how it might be modified or

[[Page 10862]]

enhanced to achieve its strategic goals of providing high-quality, 
reliable, and efficient service in a financially sustainable manner. 
The Postal Service determined that it is not possible to effectively 
optimize transportation and to be financially sustainable within the 
constraints of the current service standards. This is why the Postal 
Service is revising the standards to explicitly accommodate the fact 
that mail and packages entered the prior day would be picked-up on the 
next day's transportation route for certain ZIP Codes, to enable 
transportation optimization while also providing customers with precise 
and reliable service expectations.
    In addition to the service standard changes, the Postal Service is 
also proposing to exclude Sundays and holidays as transit days for 
measurement for mail and packages that enter the Postal Service's 
network on Saturday or the day before a holiday. Certain commenters 
shared concerns that this change would further delay the delivery of 
mail and packages. In reality, this change affects only a small amount 
of mail volume. By removing this constraint, as most of the Postal 
Service's competitors and other foreign postal operators have done, the 
Postal Service will be able to achieve additional operational 
efficiencies and costs savings with minimal impact on volume, including 
building density, creating higher throughputs, and staffing with more 
flexibility.
    Currently, because Sundays and holidays count as transit days, the 
Postal Service is forced to process volume that was entered at delivery 
or retail on Saturdays (or immediately before holidays) for immediate 
dispatch into the network on Sunday mornings (or on holiday mornings). 
Excluding Sundays and holidays as transit days for measurement for mail 
and packages entered on Saturday or the day before a holiday will 
further establish more precise and achievable service expectations. 
This ensures consistent service standards across all Post Offices and 
product categories and would avoid complications with implementing 
different measurement standards for different locations and would 
provide predictable service levels nationwide.
    Finally, the Postal Service notes that the abovementioned comments 
focus almost exclusively on delivery speed. In their view, even the 
modest (one day) increase in service standards for a small minority of 
volume, within the current day ranges, is unreasonable and 
disqualifying. However, when establishing service standards, the Postal 
Service must balance competing policies, with delivery speed serving as 
just one consideration. As described further below, the new service 
standards and related operational initiatives appropriately balance 
competing priorities, as they will revitalize and modernize the Postal 
Service's network and significantly reduce costs, promote financial 
sustainability, provide the same or enhanced service standards for most 
volume, and deliver greater service reliability overall. These changes 
will help to ensure that the Postal Service is able to provide 
universal postal services into the future. There is little value to 
customers in prioritizing speed at any cost in the short term if that 
means that the Postal Service is unable to adjust to changing market 
dynamics, falls further into financial insolvency, and becomes unable 
to provide universal postal services in years to come. Accordingly, 
having considered the abovementioned comments, the Postal Service has 
determined that they do not necessitate any revisions to the Proposed 
Rule.

B. Disparate Impact on Rural Communities and Network Consolidations

    A few commenters claimed that the service standard changes as 
designed will impact rural customers more than urban customers, and 
that this impact is inappropriate. For example, one commenter stated, 
``Given that most post offices outside the 50-mile boundary are in 
rural communities, these areas will disproportionately see their 
service downgraded.'' She also claimed that not one community within 
Wyoming, South Dakota, or Vermont falls within a 50-mile radius of an 
RPDC, and therefore, these entire states would be subject to RTO 
without any upside. Similarly, many individuals shared concerns 
regarding the closure, perceived downgrading, and/or consolidation of 
processing facilities, particularly in rural areas, including in the 
state of Wyoming. They argued that it is inefficient and time consuming 
to send mail, particularly intrastate mail, out of state for 
processing.
    Neither RTO nor the revised service standards single out rural 
areas; they are instead predicated on a uniform rule that applies 
equally across urban and rural areas and that affects more urban volume 
than rural volume overall. Rural and urban areas alike will receive a 
mix of service standard upgrades and downgrades. Further, even 
customers who may experience a service downgrade for mail they are 
sending will benefit from the increased efficiencies that will be 
gained, particularly for mail they are receiving. As noted above, the 
majority of mail and package volume, including mail and package volume 
destined to rural communities, originates in ZIP Codes that are within 
50 miles of an RPDC. This volume will not be impacted by RTO and can be 
processed more quickly, as it will no longer need to wait for volume 
arriving from outlying areas.
    These claims also ignore the efforts the Postal Service has taken 
to mitigate the already limited impact the changes will have on rural 
communities. The service standard changes preserve regular and 
effective access to postal services in all communities, including those 
in rural areas or where Post Offices are not self-sustaining. As noted 
above, the changes maintain the existing service standard day ranges 
for First-Class Mail, meaning no such mail will have a standard of more 
than 5 days, and service within these ranges will be more predictable 
and reliable. The changes also include a 2-3-day local turnaround 
service within a region and within certain local areas. Due to the 
financial and efficiency gains from the operational and service 
standard changes, and in recognition of specific concerns raised by 
stakeholders that value local turnaround service, the Postal Service 
initially identified 16 LPCs that would maintain some originating 
processing operations and is announcing additional LPCs that would 
likewise maintain some originating processing, including local 
cancellation, to facilitate more local turnaround mail. The Postal 
Service has recently announced additional LPCs that will include these 
originating operations and intends to identify additional qualifying 
LPCs as appropriate based on an assessment of operational 
considerations. This means that more ZIP Codes will fall within the 
service areas for 2-3-day local turnaround. For example, while Vermont, 
South Dakota, and Wyoming may not have an RPDC located in the state, 
they will now each have at least one LPC with 2-3-day local turnaround 
service for Single Piece First-Class Mail originating and destinating 
in the local area, and Single Piece First-Class Mail that originates in 
Vermont, South Dakota or Wyoming and destinates within the same RPDC 
service area will have a 3-day standard. Furthermore, significant 
percentages of Presort First-Class Mail (including critical mail like 
bills and government communications), First-Class Mail overall, and 
other market-dominant products will be upgraded for both rural and 
urban ZIP Codes once the final rule is fully effective. Neither access 
to, nor the list of services provided at, Post Office locations is 
changing.

[[Page 10863]]

    With respect to individuals who expressed concerns that facility 
closures and consolidations would result in local mail being processed 
in another state, the reality is that a majority of the mail collected 
locally does and will travel across the Postal Service's wider 
transportation and processing network over significant distances to 
reach their final destinations. A very high percentage of mail (often 
80 to 90 percent) that originates in a specific city or county is 
destined for other parts of the state, country, or world. In other 
words, almost all mail that is sent in any local area across the 
country is bound for another local area, and almost all mail being 
delivered in any local area did not originate in that local area. Mail 
and packages destined for outside the local area will receive better 
service and be more cost effectively distributed, by aggregating them 
with mail and packages from other areas going to the same places that 
will likewise utilize the wider postal network and be transported 
significant distances from where the mail originated. So, making its 
first processing stop further away serves to hasten its travel, not 
slow it. While this might seem counterintuitive, it is very consistent 
with logistics and mail processing reality and practice. One must only 
look at analogous express package carriers who operate out of a single 
or a handful of U.S. hubs to find evidence of this common practice for 
speed and efficiency.
    The Postal Service's legacy network consists of hundreds of 
facilities that were established without any overarching design or 
rationale--they were deployed ad hoc, as needed, and they do not 
reflect any systematic placement of where certain functions should take 
place for the greatest network efficiency. Right now, the geographic 
location of any given processing or sortation operation is not 
necessarily the best place for it. This has led to excess truck trips, 
half-empty trucks, redundant functionality and equipment, and a large 
amount of deferred maintenance, among a host of other illogical and 
unsustainable inefficiencies. The Postal Service's DFA Plan involves 
determining the most logical, cost-efficient location for a given 
operation and implementing infrastructure changes and facility 
investments accordingly, all while leveraging a vast embedded 
infrastructure to the greatest extent possible. These changes will 
position the affected facilities for the most efficient flow of mail 
and packages and thus for success and relevance in the current and 
future marketplace. The facilities are not being ``downgraded,'' 
because there is no inherent value in how many different operations a 
facility performs. A facility's value comes from its utility to the 
overall system, and the changes and investments under the DFA Plan 
actually ensure that these facilities have value by adjusting their 
roles toward what is needed as part of a more optimal and financially 
sustainable network.
    As the Proposed Rule carefully balances the need to increase 
operational efficiencies and reduce costs, while also continuing to 
provide timely and reliable postal services to all communities, and 
also includes measures designed to mitigate the effect on impacted 
communities, the Postal Service has determined that changes are not 
needed to address comments regarding the impact on rural communities or 
facility closures/consolidations prior to implementing the final rule. 
Though, while it does not necessitate a change to the rule, the Postal 
Service does note that more LPCs will provide local turnaround service 
than originally planned, as described in more detail above. As 
described above, this means that more ZIP Codes will fall within the 
service areas for 2-3-day local turnaround.

C. Financial Considerations

    A few of the commenters raised cost-related concerns, including a 
concern that costs are not a legitimate consideration when setting 
service standards. For example, one commenter claimed that prioritizing 
financial self-sufficiency over delivery speed is inconsistent with the 
statutory framework Congress created. Others questioned whether the 
Postal Service's projected efficiencies and cost-savings are reliable 
and/or whether they outweigh potential harms. A few commenters 
suggested that the Postal Service should, in lieu of the changes, 
pursue other business ventures, such as offering banking services or 
further incentivizing Presort and Destination Entry volume, as a means 
to reduce costs and increase revenues.
    As noted in the Postal Service's Reply Brief, financial 
sustainability is a legal requirement and a practical necessity. A 
central purpose of postal policy since the creation of the Postal 
Service in 1970 is the provision of universal services in a financially 
self-sufficient manner. The pre-1971 Post Office Department was 
dependent on Congressional appropriations to cover its operating 
deficits; by contrast, Congress sought in the Postal Reorganization Act 
to free the Postal Service from political interference, enable the 
achievement of its universal service mission in a more business-like 
manner, and eventually to become self-sufficient. Neither in the Postal 
Accountability and Enhancement Act nor, subsequently, in the Postal 
Service Reform Act did Congress waver in its commitment to this 
fundamental policy. A few commenters appeared to be confused about the 
Postal Service's status and objected to the proposed changes on the 
mistaken understanding that the Postal Service is taxpayer funded. 
Other commenters simply ignored this fundamental aspect of the 
statutory scheme. For example, one commenter claimed that, because 
Title 39 ``does not direct the Commission to consider the Postal 
Service's ability to achieve financial self-sufficiency when evaluating 
a change to service standards,'' the Commission ``should not defer to 
the Postal Service's claimed discretion to balance the directives of 
the statute against its perceived financial needs.'' This claim is 
clearly inconsistent with the statutory scheme, whose plain text 
directs the Postal Service to establish an effective and economical 
postal system whose costs are covered through postage rates and fees, 
not annual appropriations. 39 U.S.C. 101, 403, 404 (b), 3622(b)(5), 
3661(a), 3691. Service standards are important drivers of the structure 
of the Postal Service network and hence the costs that the Postal 
Service incurs, and it would be impossible to achieve these statutory 
obligations if the Postal Service set service standards without regard 
for costs, particularly in an environment of yearly sustained losses 
and steadily dwindling cash. In fact, the statute explicitly directs 
the Postal Service to do so in section 3691(b)(1)(C), which recognizes 
the need to balance service considerations against ``reasonable rates 
and best business practices,'' a balancing that necessarily requires 
effective cost management and adaptations of the postal network to 
changing market dynamics. See also 39 U.S.C. 3691(c)(4) and (6)-(8). 
This language recognizes that the Postal Service has three choices 
under the statute to cover its costs as circumstances change: raise 
revenue, cut costs (through improved efficiency or reduced cost of 
performance), or both. If the Postal Service does not ensure that 
service standards align with an efficient network, its only alternative 
under the statutory scheme would be to cover those excess costs through 
higher rates, but market-dominant products are statutorily limited by a 
price cap.
    For as long as the Postal Service is required by law to self-fund, 
it is

[[Page 10864]]

incumbent that the Postal Service consider costs while designing 
service standards, formulating operational strategies, and identifying 
opportunities for improved efficiency. This is not to say that the 
Postal Service considered cost alone in structuring the service 
standard changes: rather the proposed changes are designed to balance 
the multiple competing objectives enshrined in Title 39, including the 
need to provide regular and effective levels of service.
    While some comments question the reliability of the Postal 
Service's projected efficiencies and cost-savings, the Postal Service's 
models and decision-making processes are robust. The strategies being 
employed are not revolutionary, but instead simply involve the 
deployment of modern approaches that any commercial logistics provider 
should use. The Postal Service's operational planning and 
implementation processes to execute on those strategies are thorough 
and systematic, and enable the Postal Service to appropriately design 
and execute on meaningful change in the real world of postal 
operations. During the advisory opinion proceeding, hundreds of pages 
of testimony and evidence were entered into the record and these 
materials support that projected annual cost savings under the Postal 
Service's proposal is approximately $3.6 to $3.7 billion. Further, in 
light of the magnitude of the Postal Service's financial problems, the 
projected cost savings outweigh the costs associated with a modest 
increase in service standards for a minority of volume, and 
appropriately balance statutory policies that require the Postal 
Service to achieve financial sustainability, create an integrated 
network, and foster reliability in its service. If the Postal Service 
is to sustain itself and continue to meet the American public's 
delivery needs, transportation must be more efficiently and effectively 
routed, and costs must be more efficiently and effectively managed than 
they are today.
    While certain commenters proposed ways to increase revenue or 
reduce costs in lieu of the proposed changes, such as by offering 
banking services or incentivizing ``drop entry and workshare 
activity,'' these proposals largely dismiss the problems the DFA Plan 
is designed to address, offer in its place no clear operational or 
financial benefits, and in some cases seem designed to serve the 
special interests of the commenter. These suggestions implicate pricing 
and product issues that lie outside of the scope of this proceeding, 
and in any event provide no reason why the Postal Service should not 
pursue a plan to eliminate billions of dollars of costs while improving 
efficiency and reliability throughout all stages of its network and 
operations.
    For the reasons stated above, the Postal Service does not believe 
any edits must be made to the Proposed Rule to address the 
abovementioned cost-related concerns.

D. Election Mail

    A few commenters expressed concerns about the impact that the 
service standard changes and network consolidations would have on 
election mail, specifically ballots. These commenters expressed 
concerns that ballots sent through the mail would no longer be 
delivered on time, resulting in the disenfranchisement of voters. Two 
of these same commenters also expressed concerns about ballots moving 
between states during mail processing, with one commenter arguing that 
ballots ``should never leave the state for any reason'' and another 
offering an example of voters in southern Utah whose ballots were sent 
to Nevada for processing and postmarking, which were postmarked after 
the state's deadline and were not counted.
    The Postal Service remains committed to the expeditious processing 
and delivery of the nation's election mail, particularly ballots. The 
Postal Service has a proven track record of timely delivering the 
nation's election mail. For example, during the 2024 general election, 
it took on average one day for the Postal Service to deliver ballots 
from voters to election officials.\1\ The Postal Service provides a 
secure, efficient and effective way for citizens to participate when 
policymakers decide to use mail as part of their elections and it will 
continue to do so following the service standard and operational 
changes.

---------------------------------------------------------------------------

    However, it is important to remember that voters are responsible 
for understanding their local jurisdiction's rules and requirements. If 
they are eligible to vote by mail and choose to do so, they should plan 
ahead to give themselves enough time to receive and then complete and 
return their ballot by their state's deadlines.
    Moreover, ballots routinely leave state boundaries. Election 
officials send ballots via mail to voters living out of state so they 
can vote absentee, including to military personnel and citizens living 
abroad. Many election jurisdictions also rely on mail service providers 
in different states to prepare and mail ballots. Restricting mail 
processing for ballots within state limits would effectively eliminate 
these longstanding practices and would lead to absurd results.
    In the case of voters in southern Utah raised by one commenter, 
certain ballots were not counted because they had a postmark date after 
the state's deadline. As the article cited within the comments 
explains, a number of those ballots were put into collection boxes too 
late to make the postmark deadline. In other words, this was not the 
result of postal operations. The voters did not mail their ballots in a 
timely fashion to satisfy their state's requirements.
    For those reasons, the Postal Service does not believe that the 
comments warrant any changes to the final rule.

IV. Explanation of Final Rule

A. Service Standards Generally

    Before describing how the service standards are revised, it is 
important to understand how service standards are structured in Postal 
Service regulations. Service standards contain two components: (1) a 
delivery day range within which mail in a given product is expected to 
be delivered; and (2) business rules that determine, within a product's 
applicable day range, the specific number of delivery days after 
acceptance of a mail piece by which a customer can expect that piece to 
be delivered, based on the ZIP Code prefixes associated with the 
piece's point of entry into the mail stream and its delivery address. 
As noted above, effective July 1, 2025, the Postal Service is 
restructuring the service standards for domestic First-Class Mail, with 
certain exceptions, as the sum of delivery days accruing across three 
successive operational legs reflecting end-to-end service from an 
originating 5-digit ZIP Code to a destinating 5-digit ZIP Code. Leg 1 
begins with collection and ends with acceptance at the applicable 
originating processing facility. Leg 2 begins with acceptance at the 
originating processing facility and ends with acceptance at the 
applicable destinating processing facility. Leg 3 begins with 
acceptance at the destinating processing facility and ends with 
delivery.
    With respect to Leg 1, the Postal Service intends to redesign 
regional transportation (routes between processing facilities, Post 
Offices, and delivery units) through the RTO initiative to address the 
significant inefficiencies that exist in local and regional 
transportation networks and to ensure service reliability and cost

[[Page 10865]]

efficiency. With respect to Leg 2, the Postal Service intends to 
systematically redesign and invest in its outmoded processing 
facilities to create a network of RPDCs and LPCs, which deploy 
standardized and logically sequenced operating plans and schedules for 
the movement of mail and packages, more sortation equipment, optimized 
transportation routes, and improved operating tactics to increase 
throughput, gain productivity, and increase asset utilization across 
the country.
    The Postal Service is revising service standards for end-to-end 
market-dominant products to align with these operational initiatives; 
these standards will be more operationally precise and specific for 
customers, enable the Postal Service to maintain or upgrade service 
standards for a majority of volume, and enhance the ability to reliably 
achieve standards. In particular, the Postal Service plans to reimagine 
how service standards are established by breaking that service into 
segments so that customers have clear, understandable, and logical 
information about the service provided to them from a 5-digit to 5-
digit ZIP Code perspective.
    For First-Class Mail, the existing day ranges will be preserved, 
meaning all mail will continue to be delivered within the existing day 
range of 1-5 days (as well as the current range of 0-1 days for USPS 
Connect[supreg] Local). For some end-to-end products within the 
contiguous 48 states (Periodicals, USPS Marketing Mail, and Package 
Services), the maximums for those day ranges will be shortened. (Unless 
specified otherwise, references in this document to the ``contiguous 
states'' or the ``contiguous 48 states'' include the District of 
Columbia.) No destination entry product standards will be changed, 
except to reflect the new RPDC/LPC network. Overall, most mail and 
packages in the contiguous 48 states will either receive the same 
service standard or an accelerated standard so that they are delivered 
faster than today, while some mail and packages under the new standards 
will have a service expectation that is longer than the current 
expectation but still within the current day-ranges.
    Specifically, current First-Class Mail standards are predicated 
solely on plant-to-plant (3-digit ZIP Code to 3-digit ZIP Code) driving 
distances. The rule will transition to 5-digit to 5-digit ZIP Code 
service standards that maintain the existing delivery day ranges while, 
for inter-RPDC volume, accurately and logically reflecting the three 
operational legs applicable to the movement of mail and packages: 
collection to origin processing facility (Leg 1), origin processing 
facility to destination processing facility (Leg 2), and destination 
processing facility to delivery (Leg 3). Distinct rules will apply to 
intra-RPDC volume (that is, First-Class Mail volume that originates and 
destinates in the same RDPC region), as well as certain intra-LPC 
volume.
    Because the current standards are predicated on plant-to-plant 
driving distances, they do not consider the regional and local 
transportation operations necessary to transport mail and packages from 
where they are collected to the processing network: that is, within a 
particular 3-digit ZIP Code, a mailpiece that originates at a Post 
Office that is 300 miles from the processing facility in which the 
mailpiece is dispatched to the network has the same standard as a 
mailpiece that originates 20 miles from that processing facility (if 
they are going to the same destination 3-digit ZIP Code). To meet the 
constraints imposed by this current approach to service standards, the 
Postal Service must structure its transportation network to ensure that 
all originating mail gets to the processing network on the day it is 
collected from customers, no matter how far away from the processing 
network it is entered. This leads to significant inefficiencies in 
regional transportation practices, because the Postal Service must 
conduct separate trips to drop-off destinating volume from the 
processing network to collection/delivery facilities in the morning (AM 
drop-off) and pick-up originating volume from the collection/delivery 
facilities to the processing network in the afternoon (PM collections), 
or alternatively pay Highway Contract Route (HCR) contractors to 
layover for multiple hours between the AM and PM legs of their routes.
    While this practice of separating drop-off and pick-up activities 
may have made sense in a different era where the volume of Single Piece 
First-Class Mail was much greater, it engenders costs and 
inefficiencies impossible to justify in today's environment. Overall, 
the current practice results in inefficient transportation--
characterized by excessive trips, poor utilization of truck capacity, 
and excess carbon emissions. In addition, the current practice reduces 
the efficiency and reliability of Leg 2 operations (processing and 
network transportation), because the need to wait for the volume from 
outlying collection/delivery facilities to arrive at the processing 
plant on the PM transportation creates a volume arrival profile which 
reduces efficiencies, requires the scheduled dispatch to the network to 
be later, and increases the likelihood either for the scheduled 
dispatch to leave late in order to wait for all of the mail and 
packages to arrive at the plant and be processed, or for mail and 
packages to not make the scheduled dispatch at all because it does not 
make it to the plant on time to be processed on that day given the 
compressed processing window. This impacts not only the efficiency and 
velocity of originating operations but can also have substantial 
negative downstream effects that reduce service performance for all 
volume.
    With respect to Leg 1, the Postal Service is implementing RTO, for 
mail originating in the contiguous states, to correct for these 
inefficiencies. Pursuant to RTO, the Postal Service will have the 
ability to structure transportation routes that go to facilities that 
are farther from the processing network so that trucks would pick up 
originating volume on the same routes that are also used to drop off 
destinating volume. The RTO initiative rationalizes the regional 
transportation network by eliminating routes and increasing truck 
utilization and thereby reduces transportation costs and the amount of 
carbon emissions. It also improves the efficiency and velocity of the 
processing network by producing volume arrival profiles that are spread 
more evenly throughout the day, enabling a more effective use of 
network resources and allowing the Postal Service to dispatch volume 
that is entered closer to processing plants (which is a majority of 
volume) earlier than is the case today. The Postal Service will 
designate 5-digit ZIP Codes for RTO when a retail/collection facility 
servicing that 5-digit ZIP Code is more than 50 miles from the RPDC 
campus. Exceptions to this 50-mile rule may be implemented under 
certain circumstances based on operational or business considerations.
    The standards will more logically and accurately reflect operations 
within Leg 1 and enable the implementation of the RTO initiative, 
thereby giving the Postal Service the ability to optimize its regional 
and local transportation. Specifically, and as part of the shift from 
the 3-digit to 3-digit ZIP Code standards to a more refined service 
calculation based on 5-digit ZIP Codes, the service standards will 
explicitly accommodate the fact that mail and packages entered the 
prior day will under RTO be picked up on the next day's transportation 
route for certain ZIP Codes. Effective April 1, 2025, certain 
mailpieces entered in ZIP Codes subject to RTO will therefore have one 
day assigned for Leg 1 in the service standards; zero days will apply 
in Leg

[[Page 10866]]

1 to pieces originating in other 5-digit ZIP Codes not subject to RTO. 
Implementing this change is the only way to correct for the significant 
deficiencies of the current network, while also ensuring that the 
standards set forth achievable, reliable, and understandable service 
expectations for customers.
    With respect to Leg 2, the standards being implemented as part of 
phase 2 reflect the increased efficiency, velocity, and reach of the 
processing and network transportation due to the operational benefits 
of the RPDC/LPC redesign and RTO. As noted above, the network of RPDCs 
and LPCs will deploy standardized and logically sequenced operating 
plans and schedules, more sortation equipment, optimized transportation 
routes, and improved operating tactics to increase throughput, gain 
productivity, and increase asset utilization across the country. In 
addition, RTO enables more efficient and accelerated originating 
processing operations, therefore allowing volumes to enter the network 
earlier. As a result of these benefits, the Postal Service will expand 
by four hours each of the existing service standard bands within Leg 2 
for First-Class Mail so that such mail can travel farther to plants 
that are a greater distance from the originating plant within the Leg 2 
bands.
    Finally, while the Postal Service is recognizing Leg 3 in the 
First-Class Mail standards, no additional days are being added for this 
leg, which is the same as the current standards.
    These adjustments to the service standards once fully implemented 
will lead to a net positive impact for First-Class Mail from a service 
standard perspective, and generally faster service for end-to-end USPS 
Marketing Mail, Periodicals, and Package Services. The service 
standards reflect the fact that the operational changes will enable 
volume to be accelerated through Leg 2, due to the benefits of the new 
network design and RTO; as a result, the Leg 2 bands for First-Class 
Mail will be expanded by four hours compared to the current standards. 
All volume will benefit from greater service reliability. Some mail 
(constituting a minority of volume) destined to the contiguous states 
will experience a service standard that is longer than the current 
service standard (although within the current day ranges), primarily 
because the Postal Service will assign one day within Leg 1 for all 
volume originating in a 5-digit ZIP Code that is subject to the RTO, as 
described below. In addition, as a result of the overall changes, a 
small volume of mail to and/or from locations outside the contiguous 
states will experience a service standard that is longer than the 
current service standards, while other volume outside the contiguous 
states will experience a service standard that is shorter than the 
current service standards. The relative upgrades and downgrades 
demonstrate the Postal Service's efforts to maintain high quality 
service and mitigate any customer impacts to the extent possible, while 
also implementing operational changes necessary to achieve the 
critical--and significant--cost savings that are necessary for 
financial sustainability.
    The service standards are a critical aspect of the DFA Plan's 
overall goals to create a financially sustainable and reliable Postal 
Service capable of achieving the universal service mission for all 
customers for years to come. In this regard, and considering the Postal 
Service's statutory obligations, the changes will enable the Postal 
Service to achieve a better balance of cost-effectiveness and 
reliability, by enabling the Postal Service to undertake critically 
necessary operational initiatives and more realistically aligning the 
service standards with operational capabilities. The final rule will 
result in much more precise and efficient network operations that 
better match current and projected mail mix and volumes, and the Postal 
Service anticipates that the changes will result in significant cost 
savings, in addition to enhancing service reliability and 
predictability. This keeps costs at reasonable levels and helps to 
ensure affordable rates. Overall, the operational changes and 
associated service standards will revitalize and rationalize the postal 
network in a way that enables the Postal Service to be a modern and 
high-performing organization.
    Pursuant to 39 U.S.C. 3661(b), on October 4, 2024, the Postal 
Service requested an advisory opinion from the Postal Regulatory 
Commission relating to these revisions to 39 CFR part 121; the 
Commission considered the request in Docket No. N2024-1. Further 
explanation and justification of the operational initiatives and the 
service standards, and how they are consistent with 39 U.S.C. 3691 and 
other provisions of law, can be found in the materials that the Postal 
Service has filed in that docket.
    The Postal Service's market-dominant service standards are 
contained in 39 CFR part 121. The specific revisions to 39 CFR part 121 
appear at the end of this document. The following is a summary of the 
revisions.

B. First-Class Mail

    Under the rule, the process for collections will not change, nor 
will access to Postal Service retail services. Instead, RTO will 
eliminate the interdependency between the time mail is collected from 
customers and network transportation schedules and plant processing 
schedules; eliminating this interdependency between local retail and 
collection operations, and network logistics and processing operations, 
is critically important to enabling the Postal Service to create a 
precise, efficient, and cost-effective network, as discussed in more 
detail above. ZIP Codes will be designated for RTO when a retail/
collection facility servicing that 5-digit ZIP Code is more than 50 
miles from the RPDC (though exceptions may apply). In situations where 
the RPDC is a campus, the 50-mile rule will be based on the location of 
the specific facility that performs cancellation operations. The rule 
generally will add no day for Leg 1 for ZIP Codes within 50 miles from 
the RPDC campus and will add one day to the service standard for ZIP 
Codes that are more than 50 miles from the originating RPDC. This will 
allow for more efficient and flexible transportation schedules and 
improve the arrival profile for mail processing operations, enabling 
the Postal Service to more timely dispatch the volume that is collected 
closer to the RPDC to the Leg 2 transportation network.
    This logic will generally apply to all end-to-end volume across 
market-dominant products. Because Leg 1 is the portion of operations 
from collection to the originating plant, this rule will not apply to 
any products entered at an RPDC, Presort First-Class Mail, or any 
destination-entered volume. For operational efficiency, the Postal 
Service is considering how to adjust when and where Presort First-Class 
Mail volume may be entered to ensure that it is not subject to RTO. 
This may result in specification of locations where Presort First-Class 
Mail can be entered, or changing the critical entry time (CET) for 
Presort First-Class Mail to ensure there is sufficient time for volume 
to enter the network. The CET is the latest time on a particular day 
that a mail piece can be entered into the postal network and still have 
its service standard calculated based on that day (this day is termed 
``day-zero''); all of the service standards are contingent upon proper 
acceptance before the applicable CET.
    RTO will provide flexibility in regional transportation scheduling, 
as the standards will accommodate the fact that mail and packages could 
under RTO be picked up the next day from the Post Office on the same 
trip that also dropped off mail at that Post Office for delivery that 
day. Explicitly accounting for this operational practice in the

[[Page 10867]]

service standards enables the Postal Service to achieve the benefits of 
RTO, while also providing customers with more precise and reliable 
service expectations. Additionally, by no longer requiring all mail to 
wait for the volumes collected from the furthest away Post Offices, the 
Postal Service will be able to accelerate the mail that is within the 
50-mile radius of an RPDC through mail processing, allowing for it to 
be dispatched to the network earlier, thus enabling the expansion of 
the Leg 2 service standard bands. As such, the addition of a day for 
Leg 1 will not necessarily equate to the addition of a day for the 
service standard overall for a given mailpiece. Rather, the service 
standard for a particular mailpiece will depend on the specific origin 
and destination and the cumulative number of days that are applicable 
across the operational segments (with no First-Class Mail having a 
service standard that exceeds five days).
    Under the rule for First-Class Mail, there are several fundamental 
changes to the calculation of service standards at Leg 2 to align with 
the end-state RPDC network. First, the measured transit path will be 
updated. The current network path used for measurement is Origin 
Processing and Distribution Center or Facility (OPDC/F) to Area 
Distribution Center (ADC) to Sectional Center Facility (SCF). The rule 
will instead measure the distance between the Originating RPDC and the 
Destination RPDC and then the distance between the Destination RPDC to 
the Destination LPC.
    Second, because of the improved arrival profiles facilitated by RTO 
and the improved efficiencies in the RPDC network, under the rule, each 
of the existing service standard bands will expand by four hours for 
First-Class Mail effective as of July 1, 2025. For example, under the 
current standards, First-Class Mail traveling three hours or less 
receives a 2-day standard. Under the changes, First-Class Mail 
traveling up to seven hours (i.e., the current three hours, plus four 
more hours) will receive a 2-day standard. The bands applicable to the 
assignment of 3-day and 4-day standards within Leg 2 will also expand 
by four hours each.
    Finally, even for pairs of originating and destinating 5-digit ZIP 
Codes where the application of the Leg 1 and Leg 2 rules noted above 
would otherwise result in a 6-day standard, the standard will 
nonetheless be capped at five days for such pairs.
    This segment-by-segment approach applies to inter-RDPC volume 
(i.e., volume that is moving across the network). Specific rules will 
apply to mail and packages originating and destinating within the same 
RPDC region (intra-RDPC volume). Specifically, the service standards 
will expand the geographic scope of such ``turnaround'' volume, which 
is volume originating and destinating within a facility's service area. 
Currently, certain intra-SCF volume receives a 2-day standard. Under 
the rule, certain intra-LPC and all intra-RPDC First-Class Mail volume 
will be subject to a new turnaround rule, which will provide for a 2- 
or 3-day standard, depending on the location of the originating mail 
volume. Specifically, processing facilities that cancel Single-Piece 
First-Class Mail on automated equipment will have a 2-day standard for 
turnaround Single-Piece First-Class Mail originating from 5-digit ZIP 
Codes within 50 miles of the cancellation location. By contrast, if 
certain originating volume is from a 5-digit ZIP Code beyond 50 miles 
of the cancellation location, the turnaround standard for Single-Piece 
First-Class Mail will be three days. The decision on which LPCs will 
maintain cancellation operations for Single-Piece First-Class Mail, and 
thus process local turnaround mail without transporting it to an RPDC, 
will be based on operational factors, such as distance from the RPDC to 
the LPC, and the volume of turnaround mail processed at the LPC. In 
situations in which the LPC retains cancellation operations, the 50-
mile rule noted above will be based on the distance from the LPC. In 
other situations, the RPDC will have cancellation operations, meaning 
the 50-mile rule will be based on the distance from the RPDC.
    Currently, a 1-day service standard is applied to intra-SCF 
domestic Presort First-Class Mail pieces properly accepted at the SCF 
before the day-zero CET. To account for the redesigned network, a 1-day 
service standard will instead apply to eligible intra-LPC Presort 
First-Class Mail pieces properly accepted at the LPC before the day-
zero CET. On the other hand, for eligible Presort First-Class Mail 
within the contiguous 48 states that is not eligible for the intra-LPC 
1-day standard, but that nevertheless originates and destinates within 
the same RPDC, a 2-day service standard will apply.
    RTO will not apply to originating locations outside of the 
contiguous 48 states; also, the service standards for domestic First-
Class Mail originating and/or destinating in such locations will not 
necessarily depend on the segment-by-segment network path. As a result, 
service standards for domestic First-Class Mail originating and/or 
destinating in such locations will generally not change; an exception, 
for example, will be application of RTO to domestic Single-Piece First-
Class Mail that (1) originates in the contiguous 48 states, (2) is 
collected in and dispatched from a 5-digit ZIP Code that is over 50 
miles in driving distance from the originating RPDC, and (3) destinates 
in the city of Anchorage, Alaska (5-digit ZIP Codes 99501 through 
99539), the 968 3-digit ZIP Code area in Hawaii, or the 006, 007, or 
009 3-digit ZIP Code areas in Puerto Rico. Nevertheless, 
notwithstanding application of RTO generally for domestic First-Class 
Mail that meets these conditions, a maximum 5-day service standard will 
be applied.
    A same-day service standard will continue to apply to USPS 
Connect[supreg] Local Mail pieces accepted at participating Destination 
Delivery Units (DDUs) before the applicable day-zero CET; for USPS 
Connect[supreg] Local Mail, Sorting & Delivery Centers are also 
considered DDUs. A 1-day service standard will continue to apply to all 
other pieces accepted as USPS Connect[supreg] Local Mail, including 
pieces accepted via carrier pick-up.
    The rule will also have certain effects on standards for 
international mail. As a result of the application of 5-digit to 5-
digit ZIP Code pairs, the service standard for outbound Single-Piece 
First-Class Mail International pieces properly accepted before the day-
zero CET will be equivalent to the service standard for domestic First-
Class Mail pieces originating from the same 5-digit ZIP Code area and 
destined to the 5-digit ZIP Code area in which the designated 
International Service Center is located. Similarly, the service 
standard for Inbound Letter Post pieces properly accepted before the 
day-zero CET will be equivalent to the service standard for domestic 
First-Class Mail pieces destined to the same 5-digit ZIP Code area and 
originating from the 5-digit ZIP Code area in which the applicable 
International Service Center is located. Because Inbound Parcel Post 
(at Universal Postal Union (UPU) rates) includes Inbound Surface Parcel 
Post (at UPU rates), and because that product is now competitively 
classified, the rule will remove it from these market-dominant service 
standards.

C. Periodicals, USPS Marketing Mail, and Package Services

    Service standards for end-to-end Periodicals and USPS Marketing 
Mail originating and destinating in the contiguous 48 states will 
generally flow from the Single-Piece First-Class Mail standards using 
the same measured travel path (disregarding standards for USPS 
Connect[supreg] Local Mail and for intra-LPC ``turnaround'' service). 
For

[[Page 10868]]

Periodicals, the general rule in relation to First-Class Mail will 
remain the same--i.e., a 3-6-day range will be applied to Periodicals, 
with the standard generally equaling the sum of the applicable First-
Class Mail service standard (disregarding standards for USPS 
Connect[supreg] Local Mail and for intra-LPC ``turnaround'' service) 
plus one day. For USPS Marketing Mail, the rule will add two days to 
the applicable First-Class Mail service standard (disregarding 
standards for USPS Connect[supreg] Local Mail and for intra-LPC 
``turnaround'' service). This means that the outer-bound for USPS 
Marketing Mail in the contiguous states will be seven days, rather than 
ten days under the current standards. For end-to-end Package Services 
within the contiguous 48 states, the rule will add two days to the 
First-Class Mail standards, after 5-9 hours of Leg 2 driving time is 
added to the applicable First-Class Mail service band; overall, this 
will reduce the outer-bound of the service standards for Package 
Services in the contiguous states to seven days, rather than the 
current eight days.
    With respect to Destination Entry Periodicals, Destination Entry 
USPS Marketing Mail, and Destination Entry Package Services, the 
service standards generally will not change, except to reflect the new 
network. That is, to correspond with the operational network and 
infrastructure changes that the Postal Service is implementing, the 
LPCs will replace the ADCs and the SCFs in the service standards. 
Likewise, the RPDCs will replace the Network Distribution Centers 
(NDCs) in the service standards. These changes will allow some 
Destination Entry Periodicals to receive an accelerated service 
standard, in part because it will no longer matter in this respect 
whether Destination ADCs (DADCs) and Destination SCFs (DSCFs) are co-
located, given that they are both being replaced by Destination LPCs 
(DLPCs).
    Under the rule, for Destination Entry Periodicals originating and/
or destinating in locations outside of the contiguous 48 states, 
service standards will largely remain unchanged, aside from facility 
nomenclature updates reflecting the network redesign, with certain 
exceptions. A small volume of mail to and/or from locations outside the 
contiguous states will experience a service standard that is longer 
than the current service standards, while some other volume outside the 
contiguous states will experience a service standard that is shorter 
than the current service standards. Currently, for example, a 3-day 
service standard is applied to Periodicals pieces that qualify for a 
DSCF rate and are properly accepted before the day-zero CET at the 
designated DSCF, if they are entered at the DSCF in Puerto Rico and 
destined to the U.S. Virgin Islands, or destined to the following 3-
digit ZIP Code areas in Alaska (or designated portions thereof): 995 
(5-digit ZIP Codes 99540 through 99599), 996, 997, 998, and 999; on the 
other hand, currently a 4-day service standard is applied to 
Periodicals pieces that qualify for a DADC rate and are properly 
accepted before the day-zero CET at the designated DADC, if they are 
entered at the DADC in Puerto Rico and destined to the U.S. Virgin 
Islands, or if they are destined to the following 3-digit ZIP Code 
areas in Alaska (or designated portions thereof): 995 (5- ZIP Codes 
99540 through 99599), 996, 997, 998, and 999. Since LPCs will replace 
ADCs, and since DLPC service standards will largely track those 
currently applied to DSCF volume, for such mail, the shorter of the two 
service standards (i.e., 3-day) will apply to Periodicals pieces that 
qualify for a DLPC rate and are properly accepted before the day-zero 
CET at the designated DLPC, if they are entered at the DLPC in Puerto 
Rico and destined to the U.S. Virgin Islands, or destined to the 
following 3-digit ZIP Code areas in Alaska (or designated portions 
thereof): 995 (5-digit ZIP Codes 99540 through 99599), 996, 997, 998, 
and 999.
    Furthermore, a 3-day service standard is currently applied to 
Periodicals pieces that qualify for a DSCF rate and are properly 
accepted before the day-zero CET at the designated DSCF, if they are 
entered at the DSCF in Hawaii and are destined to American Samoa; on 
the other hand, currently a 4-day standard applies to Periodicals 
pieces that qualify for a DADC rate, are properly accepted before the 
day-zero CET at the designated DADC, and are destined to American 
Samoa. For reasons of operational feasibility, under the rule, a 4-day 
service standard will be applied to Periodicals pieces that qualify for 
a DLPC rate and are properly accepted before the day-zero CET at the 
designated DLPC, if they are destined to American Samoa.
    Finally, as the service standards themselves have been simplified, 
the tables depicting day-ranges for non-contiguous states and 
territories at the end of Part 121 (Tables 2 and 4) likewise have been 
streamlined. Table 2 reflects the general standards for end-to-end day-
ranges for the non-contiguous states and territories, including 
exceptions for some intermodal transportation. Table 4 reflects the 
general standards for destination entry day-ranges for the non-
contiguous states and territories, including consolidated day-ranges 
resulting from LPCs and RPDCs superseding SCFs, ADCs, and NDCs.

Sec.  121.0  Market-Dominant Product Service Standards.

    Service standards in this part are contingent upon proper 
acceptance before the applicable day-zero Critical Entry Time (CET). 
Applying the service standards appearing in this part, effective 
service standards for combinations of 5-digit originating ZIP Codes and 
5-digit destinating ZIP Codes can be found in a lookup table at 
www.usps.com.


Sec.  121.1  First-Class Mail.

    (a) Service Standards Based on Delivery Legs Within the Contiguous 
48 States. Except as specified in paragraph (b) of this section, 
service standards for domestic First-Class Mail, whose origin and 
destination are within the contiguous 48 states, are calculated as the 
sum of service expectation days between 5-digit ZIP Code pairs, 
accruing across three successive legs as follows:
    (1) Leg 1. Unless an exception applies due to operational or 
business considerations, for this leg:
    (i) One service expectation day is added to First-Class Mail 
(excluding eligible Presort First-Class Mail) originating in a 5-digit 
ZIP Code when a facility from which mail is dispatched for the 
originating 5-digit ZIP Code is over 50 miles in driving distance from 
the originating Regional Processing and Distribution Center or Campus 
(RPDC); and
    (ii) Zero service expectation days are added for all other First-
Class Mail, including Single-Piece First-Class Mail when no facility 
from which mail is dispatched for the originating 5-digit ZIP Code is 
over 50 miles in driving distance from the originating RPDC, and 
including eligible Presort First-Class Mail.
    (2) Leg 2. (i) Two service expectation days are added to First-
Class Mail if the combined drive time between the originating RPDC, the 
destinating RPDC, and the destinating Local Processing Center (LPC) is 
7 hours or less;
    (ii) Three service expectation days are added to First-Class Mail 
if the combined drive time between the originating RPDC, the 
destinating RPDC, and the destinating LPC is more than 7 hours and not 
more than 24 hours;
    (iii) Four service expectation days are added to First-Class Mail 
pieces if the combined drive time between the originating RPDC, the 
destinating RPDC, and the destinating LPC is more than 24 hours and not 
more than 45 hours; and
    (iv) Five service expectation days are added to all remaining 
First-Class Mail pieces, except that four days are added to any such 
First-Class Mail for which a day is added under Leg 1.
    (3) Leg 3. No service expectation days are added in Leg 3.
    (b) Exceptions to Service Standards Based on Delivery Legs Within 
the Contiguous 48 States. (1) A same-day service standard applies to 
USPS Connect[supreg] Local Mail pieces accepted at participating 
Destination Delivery Units, and a one-day service standard applies to 
all other pieces accepted as USPS Connect[supreg] Local Mail.
    (2) A one-day service standard applies to eligible intra-LPC 
Presort First-Class Mail pieces accepted at the LPC.
    (3) For First-Class Mail that is not USPS Connect[supreg] Local 
Mail, with respect to ``turnaround'' service for pieces originating and 
destinating within the same RPDC service area or within the same LPC 
service area for certain qualifying LPCs (designated by the Postal 
Service based on operational considerations such as an LPC's distance 
from its servicing RPDC and volume processed at the LPC):
    (i) A two-day service standard applies to:
    (A) Eligible Presort First-Class Mail that is not eligible for a 
one-day service standard under paragraph (b)(2) of this section and 
that originates and destinates in the same RPDC service area; and
    (B) Single-Piece First-Class Mail originating in a 5-digit ZIP Code 
when no facility from which mail is dispatched for the originating 5-
digit ZIP Code is over 50 miles in driving distance of the originating 
RPDC or qualifying LPC and destinates within the same RPDC's or 
qualifying LPC's service area.
    (ii) A three-day service standard applies to Single-Piece First-
Class Mail originating in a 5-digit ZIP Code when a facility from which 
mail is dispatched for the originating 5-digit ZIP Code is over 50 
miles in driving distance of the originating RPDC or qualifying LPC and 
destinates within the same RPDC's or qualifying LPC's service area.
    (c) Service Standards for Domestic First-Class Mail Originating 
and/or Destinating in Locations Outside of the Contiguous 48 States. 
(1) A same-day service standard applies to USPS Connect[supreg] Local 
Mail pieces accepted at participating Destination Delivery Units.
    (2) Except as provided in paragraph (c)(3) of this section, a one-
day service standard applies to:
    (i) Eligible intra-LPC Presort First-Class Mail pieces accepted at 
the LPC, whose origin and destination are outside the contiguous 48 
states; and
    (ii) All other pieces accepted as USPS Connect[supreg] Local Mail.
    (3) A two-day service standard applies to:
    (i) Eligible Presort First-Class Mail that originates in Puerto 
Rico and destinates in the U.S. Virgin Islands, or vice versa;
    (ii) Eligible intra-LPC Presort First-Class Mail with an origin or 
destination that is in American Samoa or one of the following 3-digit 
ZIP Code areas in Alaska (or designated portions thereof): 995 (5-digit 
ZIP Codes 99540 through 99599), 996, 997, 998, and 999; and
    (iii) Other intra-LPC First-Class Mail pieces whose origin and 
destination are outside the contiguous 48 states, including any other 
intra-LPC Presort pieces that are not eligible for a one-day service 
standard.
    (4) A four-day service standard applies to First-Class Mail pieces 
if the same-day, one-day, or two-day service standards do not apply 
and:
    (i) The origin is in the 006, 007, or 009 3-digit ZIP Code areas in 
Puerto Rico, and the destination is in the contiguous 48 states;
    (ii) The origin is in Hawai[revaps]i, and the destination is in 
Guam, or vice versa;
    (iii) The origin is in Hawai[revaps]i, and the destination is in 
American Samoa, or vice versa;
    (iv) Both the origin and destination are within Alaska; or
    (v) Such mail originates in a 5-digit ZIP Code where no facility 
from which mail is dispatched for that 5-digit ZIP Code is over 50 
miles of driving distance from its originating RPDC, and the origin is 
in the contiguous 48 states and the destination is in the city of 
Anchorage, Alaska (5-digit ZIP Codes 99501 through 99539), the 968 3-
digit ZIP Code area in Hawai[revaps]i, or the 006,

[[Page 10870]]

007, or 009 3-digit ZIP Code areas in Puerto Rico.
    (5) A five-day service standard applies to all remaining domestic 
First-Class Mail pieces originating and/or destinating outside the 
contiguous 48 states.
    (d) Service Standards for International First-Class Mail. (1) The 
service standard for Outbound Single-Piece First-Class Mail 
International[supreg] pieces is equivalent to the service standard for 
domestic Single-Piece First-Class Mail pieces originating from the same 
5-digit ZIP Code area and destined to the 5-digit ZIP Code area in 
which the designated International Service Center, or its functional 
equivalent, is located.
    (2) The service standard for Inbound Letter Post pieces from the 
first USPS scan is equivalent to the service standard for domestic 
Single-Piece First-Class Mail pieces destined to the same 5-digit ZIP 
Code area and originating from the 5-digit ZIP Code area in which the 
applicable International Service Center, or its functional equivalent, 
is located.


Sec.  121.2  Periodicals.

    (a) End-to-End. (1) Except as provided in paragraph (a)(2) of this 
section, a 3- to 6-day service standard applies to end-to-end 
Periodicals pieces, with the standard generally equaling the sum of one 
day plus the applicable Single-Piece First-Class Mail (FCM) service 
standard (disregarding standards for USPS Connect[supreg] Local FCM and 
for intra-Local Processing Center ``turnaround'' service).
    (2) For certain end-to-end Periodicals pieces originating and/or
