September DMM Update


Postal Explorer® ( is your source for up-to-date 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. Today we updated our mailing standards to capture the following changes:


Alternative Addressing Format Options
We revised
507.1.0 and 602.3.0 to permit the use of certificates of mailing, Confirm service, Delivery Confirmation, and special handling extra services when using an alternative address format.


Contents of Periodicals Mail
We revised
707.3.0 to incorporate "content" changes to the standards governing pages, supplements, products and product samples, and mailpiece design.


New Endorsement for Returned Mailpieces
We revised
Exhibit 507.1.4.1 to add a new endorsement, "Returned to Sender, Item Contains Nonmailable Contents," for mailpieces that are returned due to contents that are nonmailable.


Commercial Flats Clarification
We revised
301.1.0 to update commercial flats text with minor editorial updates, and to rearrange the DMM reference text for better flow.


Clarification of Standards for Parcel Select
We revised
453.3.0 to remove standards for loyalty and growth rebates. We also revised 602.1.5.3 to note that all Parcel Select pieces must have a return address.


Delivery Address Visibility in Window Envelopes
We revised
202.2.1 and 302.2.1 to add a reference to current standards that require the delivery address to be completely visible within a window envelope, when used.


New Font Size Option for Optional Endorsement Lines
We revised
708.7.2 to provide a new font size option for mailers applying an optional endorsement line (OEL) to their mailpieces that do not bear a traditional Address Change Service (ACS) participant code.


Confirmation Services to the Northern Mariana Islands—ZIP Code 96952
We revised 503.9.2.4 and 503.10.2.3 to eliminate the Northern Mariana Islands (ZIP Code 96952) from the tables of ineligible ZIP Codes to receive Delivery Confirmation and Signature Confirmation services.


Our next scheduled DMM update is October 4.
