April 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. Today we updated our mailing standards to include the following changes:

Elimination of Fees

We revised various sections of the DMM to clarify the standards for the applicability of certain fees. We published this information in the March 2, 2017, Postal Bulletin.

Additional Domestic Mailing Services Products Changes

We revised the DMM in various sections as a result of the increase in the letter-size mail weight limit to 3.5 ounces published in the Federal Register on December 21, 2016. These revisions include other related changes for clarification. We published this information in the March 16, 2017, Postal Bulletin.

USPS Marketing Mail Markings

We revised 202.3.5 and 604.5.3 in reference to provide some examples of the new markings and will add information on the pending implementation in each section. We published this information in the March 16, 2017, Postal Bulletin.

Electronic Induction (eInduction^®) Option

We revised 705.20.0, adding the Electronic Induction (eInduction^®) Option. We published this information in the March 16, 2017, Postal Bulletin.

Seamless Acceptance Program

We revised 705.22.0, adding the Seamless Acceptance Program. We published this information in the March 16, 2017, Postal Bulletin.

We published this information in the March 16, 2017, Postal Bulletin.

Customized MarketMail Prices

We revised 243.1.0 to add price information for Customized MarketMail^®. This revision is for clarity only, and does not affect the price paid. We published this information in the March 16, 2017, Postal Bulletin.
