Following are the most recent revisions to the Domestic Mail Manual, organized by topic.

Characteristics and Content

C200.1.10 is revised to add a new option for the endorsement location on Periodicals mailpieces with Ride-Along attachments or enclosures. Mailers may now place the words “Ride-Along Enclosed” on the label carrier when including a Ride-Along piece in a Periodicals mailing. This option is added to be consistent with the standards for First-Class Mail and Standard Mail enclosures and attachments.

C850 is revised to clarify and correct various mailing standards for barcoding parcels. In addition, we added exhibits to better define this section and illustrate the barcode formats.

Eligibility

E260.1.4 also is revised to add a new option for the endorsement location on Periodicals mailpieces with Ride-Along attachments or enclosures. Mailers may now place the words “Ride-Along Enclosed” on the label carrier when including a Ride-Along piece in a Periodicals mailing. This option is added to be consistent with the standards for First-Class Mail and Standard Mail enclosures and attachments.

General Information

Revisions were made throughout the DMM to reflect that the three rates and classification service centers (RCSCs) and the Nonprofit Service Center (NSC) were consolidated into one unit, the Pricing and Classification Service Center (PCSC). The duties and areas covered by the New York RCSC, Chicago RCSC, San Francisco RCSC, and Memphis NSC will be served by the new PCSC. The new PCSC will ensure consistent application of USPS rates and mailing standards by providing one source for mail classification decisions, one staff, and a one-stop-shop for customers and field employees to consult on rate application and mail eligibility questions.

G995 is added to establish the rate, eligibility criteria, mailing standards, and classification information for the new Priority Mail flat-rate box experiment. The Postal Service is conducting this experiment to enhance customer convenience through the introduction of two flat-rate box options for Priority Mail. Much like the Priority Mail flat-rate envelope offered since 1991, the flat-rate box gives customers a single, predetermined rate, regardless of the actual weight or destination of the mailpiece. This experiment is expected to last for two years.

Labeling Lists

L001, L004, L007, L606, L801, and L802 are revised to reflect changes in mail processing operations.
