May DMM Update


Postal Explorer® ( is your source for up-to-date mailing standards. The Domestic Mail Manual (DMM®) is fully searchable on Postal Explorer and features fly-out menus, cross-reference links, and an extensive subject index. Today we updated our mailing standards to include the following changes:

Qualified Business Reply Mail—Revised PS Form 6805

We revised 505.1.0 to expand the use of PS Form 6805, Qualified Business Reply Mail™ (QBRM) Application, to include Business Reply Mail® (BRM) ZIP+4® Code assignments and validations. We published this information in the April 3, 2014, Postal Bulletin.


Inclusion of “Diplomatic Post Office (DPO)” for Mail Balloting Materials

We revised 703.8.2.2 to clarify that eligible balloting materials may be mailed without prepayment of postage when deposited at a Diplomatic Post Office (DPO). We published this information in the April 17, 2014, Postal Bulletin.


Inclusion of “Diplomatic Post Office (DPO)” When Sending Hazardous, Restricted, or Perishable Materials

We revised 703.2.3.1 to clarify that hazardous, restricted, or perishable materials mailed to, from, and between Diplomatic Post Offices are subject to the conditions of International Mail Manual (IMM®) 130; the standards in DMM 601; Publication 52, Hazardous, Restricted, and Perishable Mail; and conditions prescribed by the Department of Defense (DOD), as listed in “Overseas Military/Diplomatic Mail” section of the Postal Bulletin. We published this information in the April 17, 2014, Postal Bulletin.


Our next scheduled DMM update is June 2, 2014.
