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


Reply Rides Free Incentive Program—Weight Increase

We revised 233.7.0 to allow First-Class Mail letters weighing over 1 ounce but no more than 2 ounces to be eligible for the Reply Rides Free incentive program.


Automated Postal Center (APC) Insurance Indemnity Increase

We revised 503.4.0 to increase the insurance indemnity available at an Automated Postal Center (APC) from $500 to $5,000.


Booklets—Tabs, Tape and Glue

We revised 201.3.11 to permit the use of additional types of glue to seal booklet-type mailpieces and folded self mailers, and to clarify the sealing method for die cut flaps.


Group E Post Office Box Service

We revised 508.4.6 to clarify eligibility, simplify the standards, and facilitate uniform administration for Group E (free) Post Office (PO) box service.


Shortpaid and Unpaid Information-Based Indicia (IBI) Postage and Shortpaid Express Mail Postage

We revised 604.4.0, 604.8.0, and 604.10.0, to implement revenue protection procedures for mailpieces entered with shortpaid and unpaid Information Based Indicia (IBI) postage payment generated by Click-N-Ship, IBI postage meters, and PC Postage products, and also to implement revenue protection procedures for shortpaid Express Mail postage.


Standard Mail Nonmachinable Letter Preparation

We revised 243.5.5 and 245.5.4 to provide a new option for sortation of nonmachinable letters.


Reassignment of ZIP Codes between Memphis NDC and Dallas NDC

We revised 246.3.0, 346.3.0, 366.4.0, 446.3.0, 453.3.0, and 466.4.0 to incorporate the following mail processing changes: Mailers preparing destination network distribution center (DNDC) mailings must change their mail preparation for mail addressed to 3-digit ZIP Code 706 destinations by labeling those containers to Memphis NDC, and enter that mail at the Memphis NDC facility rather than at the Dallas NDC facility. Mailers with DNDC mailings must also change their preparation for mail for 3-digit ZIP Codes 713 and 714 by labeling those containers to the Dallas NDC rather than the Memphis NDC.


Our next scheduled DMM update is October 3.
