June DMM Update

Postal Explorer ( is your source for the latest mailing standards. The Domestic Mail Manual is fully searchable on Postal Explorer and features fly-out menus, cross-reference links, and an extensive subject index. We updated our standards with the following changes:

Postage Refund Appeals

We revised 604.9.2.8 to update the contact information for appealing denied refunds of unused meter postage.

Cigarette Lighters

We revised 601.10.13.4 to limit cigarette lighters in the mail to those approved for shipping by an authorized DOT lighter certification agency.

Labeling Lists

We revised the labeling lists to reflect changes in mail processing operations.

Our next scheduled DMM update is July 1.

Letter-Size Booklets and Folded Self-Mailers – Reminder

All letter-size booklets and folded self-mailers mailed as presorted machinable letters must meet the same physical standards required for automation letters. On September 8, we are changing the construction and sealing standards for letter-size booklets. We encourage mailers to review the April 11 Federal Register notice, β€œNew Standards for Letter-Size Booklets,” on Postal Explorer at (click Federal Register notices) to prepare for the change.
