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. Monday, July 10, 2017, we updated our mailing standards to include the following changes:

Parcel Select Lightweight® Dimensional Criteria

We revised 201.7.6 and to clarify the dimensional criteria of Parcel Select Lightweight® (PSLW) parcels. We published this information in the June 22, 2017, Postal Bulletin.

Preparing Pallets

We revised 705.8.0 to clarify the maximum number of pallets that may be stacked, and the securing method for trays prepared on a pallet. We published this information in the June 8, 2017, Postal Bulletin.

Domestic Mail Manual Simplification

We revised DMM in various chapters as we continue our simplification initiative without changes to standards to make it quicker, easier, and more convenient. To assist in this transition the Postal Service will post a crosswalk for each section of the DMM. We published this information in the June 8, 2017, Postal Bulletin.

Address Information System Services

We revised 509.1.0 to clarify the processes for obtaining delivery statistics and update the required method to receive product updates from the Postal Service. Additionally, various DMM subsections will also have minor revisions related to the aforementioned clarification and update. We published this information in the May 25, 2017, Postal Bulletin.

Our next scheduled DMM update is August 7, 2017.
