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 capture the following changes:


Bundle Preparation - Strapping Transparency

We revised 300, 400, 705 and 707 to provide standards for the transparency characteristic of clear strapping.


Clarification on Processing Refund Requests for Unused Meter Indicia

We revised 604.9.3 to clarify the standards that apply to the payment of approved refund requests for unused postage evidencing system indicia.


Forwarding and Return Service for Parcel Select Mailpieces

We revised 507.1.0 and 507.2.0 to discontinue the free local forwarding of Parcel Select mailpieces and to eliminate the option to request discontinuance of forwarding.


New Authorization Process for Mailers Using Special Postage Payment Systems

We revised 705 to reflect a new authorization process for mailers wishing to mail under a special postage payment system, and to remove reference to fixed 2-year authorization periods.


New Standards for Round-Trip Mailings of Optical Discs

We revised 100, 200, 300, and 500 to provide new standards for round-trip mailings with one standard optical disc no larger than 12 centimeters in diameter enclosed per mailpiece.


Adult Signature Service

We revised 503, 508.7.2, 601.11.6, and 703.3.2, to add a new extra service called Adult Signature.


Mobile Barcode Promotion

We revised 709.4.0 to add a temporary promotion for First-Class Mail cards, letters and flats, and Standard Mail letters and flats bearing two-dimensional mobile barcodes.


Our next scheduled DMM update is August 1.
