**SUPPLEMENTARY INFORMATION:**
The *International Mail Manual* (IMM) provides our standards for all international mailing services and references for the applicable prices. It was issued on January 21, 2024, and was updated with *Postal Bulletin* revisions through December 28, 2023. It replaces all previous editions.
The IMM continues to enable the Postal Service to fulfill its long-standing mission of providing affordable, universal mail service. It continues to: (1) increase the user's ability to find information; (2) increase the user's confidence that he or she has found the information they need; and (3) reduce the need to consult multiple sources to locate necessary information. The provisions throughout this issue support the standards and mail preparation changes implemented since the version of July 10, 2022. The *International Mail Manual* is available to the public on the Postal Explorer® internet site at *https://pe.usps.com.*
