October DMM Update

Postal Explorer^® (pe.usps.com) is your source for up-to-date mailing standards. The Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM^®) is fully searchable on Postal Explorer and features fly-out menus (menus that when moused over drop down to the side displaying subsections of the DMM), cross-reference links, and an extensive subject index.

Effective October 6, 2014, we continued our initiative to reduce the size of the DMM without changes to content to make it quicker, easier, and more convenient to use.

Section 604, Postage Payment Methods, was renamed Postage Payment Methods and Refunds; Sections 705.20.0, Postage Due Weight Averaging Program and 705.24.0, Scan Based Payment were relocated to Section 604 as Sections 604.11.0 and 604.12.0, respectively. Also, Section 705.25, Alaska Bypass Service, was relocated under Section 608.2.0, Domestic Mail, as sub-section 608.2.6.

Our next scheduled DMM update is December 8, 2014.
