Domestic Mail Manual; Incorporation by Reference

AGENCY: Postal Service.

ACTION: Final rule.

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

SUMMARY: The Postal Service announces the issuance of the Mailing 
Standards of the United States Postal Service, Domestic Mail Manual 
(DMM[supreg]), updated November 2, 2026, and its incorporation by 
reference in the Code of Federal Regulations.

DATES: This rule is effective November 4, 2026. The incorporation by 
reference of certain material listed in this rule is approved by the 
Director of the Federal Register as of November 4, 2026.

FOR FURTHER INFORMATION CONTACT: Alison Fassett at (202) 268-8045.

SUPPLEMENTARY INFORMATION: The DMM provides the United States Postal 
Service's official prices and standards for all domestic mailing 
services. The most recent issue of the DMM was updated on November 2, 
2026.
    This issue of the DMM contains all Postal Service domestic mailing 
standards and continues to: (1) increase the user's ability to find 
information; (2) increase confidence that users have found all the 
information they need; and (3) reduce the need to consult multiple 
chapters of the DMM to locate necessary information. The issue updated 
on November 2, 2026, sets forth specific changes, including new 
standards throughout the DMM to support the standards and mail 
preparation changes implemented since the version updated on April 7, 
2025.
    The online version of the DMM is available via the Postal 
Explorer[supreg] website at: <a href="https://pe.usps.com">https://pe.usps.com</a>. Changes to mailing 
standards will continue to be published through Federal Register 
documents and the Postal Bulletin and will appear in the next online 
version of the DMM.
