Domestic Mail Manual; Incorporation by Reference

The Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM) provides the United States Postal Service's official prices and standards for all domestic mailing services. The most recent issue of the DMM is dated April 7, 2025.

The issue dated April 7, 2025, sets forth specific changes, including new standards throughout the DMM to support the standards and mail preparation changes implemented since the version issued on January 21, 2024.
