General Information on Postal Service
The Postal Service will issue a redesigned Domestic Mail Manual (DMM). The redesigned manual is renamed, Mailing Standards of the United States Postal Service, Domestic Mail Manual, and replaces the former Domestic Mail Manual, Issue 58. The redesigned manual is not intended to alter existing standards in DMM 58, and contains the mailing standards effective through January 6, 2005. The new manual presents USPS domestic mailing standards in a manner that increases usability and provides better access to USPS products and services.
