Effective November 3, 2025, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), in various sections, to clarify Postal Service standards for overseas military and diplomatic Post Office® mail.
The Postal Service is reorganizing the text of DMM section 703.2.0, “Overseas Military and Diplomatic Post Office Mail,” for consistency within the DMM. For clarity and consistency, the Postal Service is also revising the text of reorganized DMM section 703.2.0 to include the Army Post Office (APO), Fleet Post Office (FPO), and Diplomatic Post Office (DPO) acronyms consistently throughout the section.
Additionally, the DMM is being revised to reflect that the Postal Service is discontinuing the Space Available Mail (SAM) and Military Ordinary Mail (MOM) services. This decision was made in consultation with the U.S. Department of Defense (DOD) and the U.S. Department of State.
Except for the discontinued SAM and MOM services; the relocation of section 703.2.3.2, related to firearms (which will be placed in Publication 52, Hazardous, Restricted, and Perishable Mail), and a few minor revisions, the current text of 703.2.0 will otherwise remain intact.
Other revisions include updating section references in the DMM index based on the reorganization of DMM section 703.2.0, and removing references to SAM and MOM services.
The Postal Service will revise the Quick Service Guide (QSG) 800, “Glossary of Postal Terms and Abbreviations in the DMM,” to reflect these changes.
Although these revisions will not be published in the DMM until November 3, 2025, they are effective immediately after being published in Postal Explorer®.
The Postal Service will incorporate these revisions into the November 3, 2025, edition of the online DMM, which is available via Postal Explorer at pe.usps.com.
