ARMY - AR 25–51
Official Mail and Distribution Management
|Publication Date:||20 March 2020|
This regulation complies with Part 102-192, Title 41, Code of Federal Regulations (41 CFR 102-192) and establishes the policies 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 colocated with APOs, but in the interest of efficiencies, colocation is strongly encouraged.
