July 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:

Domestic Mail Manual Streamlining

We revised Sections 203, 207, 601, 608, 703, and 705, continuing our initiative to reduce the size of the DMM without changes to standards.


eDoc Volume Criteria for Single-Piece First-Class Mail

We revised DMM 604.5.1 to permit less than the current minimum volume for permit imprint mailings when mailers submit electronic postage statements and piece-level barcode information for single-piece First-Class Mail. We published this information in the June 12, 2014, Postal Bulletin.


Clarification-Centralized Account Processing System (CAPS)

We revised various sections of the DMM to correct references to Centralized Account Processing System (CAPS) inadvertently listed as Centralized Account Payment System. We published this information in the June 26, 2014, Postal Bulletin.


Clarification of Permit Fee Waiver in Participation Requirements for Full-Service Pieces

We revised DMM 705.23.3c. to clarify the permit fee waiver in participation requirements for Full-Service pieces. We published this information in the June 26, 2014, Postal Bulletin.


Deferral of Effective Date: Elimination of Business Reply Mail (BRM) Parcels

We revised DMM 505.1.4.1 to defer the effective date for eliminating mailers’ option to use Business Reply Mail (BRM) to pay postage for parcel-shaped items. We published this information in the June 26, 2014, Postal Bulletin.


Revised Postage and Fee Refund Criteria

We revised DMM 604.9.0 to update the hourly charges and related postage threshold used in assessing certain types of postage refunds and to provide the allowable time periods for requesting refunds for extra service fees. We published this information in the June 26, 2014, Postal Bulletin.


Our next scheduled DMM update is September 7, 2014.
