June 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 June 4, 2014, we introduced a streamlined version of the DMM. This is the first step in an initiative to reduce the size of the DMM without changes to content to make it quicker, easier, and more convenient to use.

Chapters 200, 300, and 400 have been consolidated to create a revised Chapter 200, “Commercial Letters, Flats, and Parcels.” We have eliminated redundant language and reorganized the remaining language for consistency and to improve flow and ease of use. Chapter 100, “Retail Letters, Flats, and Parcels,” has also been streamlined.

Additionally, the applicable Quick Service Guides (QSGs) have been renumbered to align with new Chapter 200 and updated with new DMM reference information. Applicable Customer Support Rulings have also been updated with new DMM reference information.

Our next scheduled DMM update is July 7, 2014.
