ARMY - DA PAM 25–53
Official Mail and Distribution Procedures
|Publication Date:||7 April 2020|
This pamphlet complies with Part 102-192, Title 41, Code of Federal Regulations (41 CFR 102-192), and establishes the procedures for all elements of the Department of the Army (DA) to administer the Official Mail and Distribution Management Program (OMDMP). The OMDMP should not be confused with Army Post Office (APO) functions. Both the Official Mail and Distribution Center (OMDC) and APO functions are separate programs. Installation OMDCs are not required to be co-located with Army Post Offices, but in the interest of efficiency, co-location is strongly encouraged.
