June DMM Update

Postal Explorer^® (pe.usps.com) 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. Yesterday, we updated our mailing standards to include the following changes:

Full-Service Automation Option

We revised 705.23.0 to add a new sub-section on the Mail Anywhere program. We published this information in the May 26, 2016, Postal Bulletin.

Extra Service Refunds

We revised 604.9.2.4g. to clarify that extra service fees will not be refunded for undeliverable Certified Mail^®, Return Receipt for Merchandise (RRM), and Signature Confirmation™ mailpieces when they have received the proper event scan (e.g., UAA, Refused, etc.). We published this information in the May 26, 2016, Postal Bulletin.

Optional Combined Parcel Mailings

We revised 705.21.1.1 to clarify that the minimum volume requirement for Parcel Select Lightweight^® parcels in a combined parcel mailing under 705.21.0, is 200 pieces or 50 pounds. We published this information in the May 26, 2016, Postal Bulletin.

Missing Mail
