February DMM Update

We update the DMM on Postal Explorer (pe.usps.com) concurrent with the first Postal Bulletin of every month, so Postal Explorer is always your most up-to-date resource for mailing information. The February 2 update includes the following changes:

Return of Prescription Drugs

We revised 601.11.11 to allow the return of prescription drugs by mail when the return is initiated by a drug manufacturer or the manufacturer's registered agent.

Labeling Lists

We revised labeling lists L001, L007, and L606 to reflect changes in mail processing operations.

Check the Summary of Changes for a complete listing of updates. You will find revisions listed by effective date and also by chapter, with clickable links to revised sections. The DMM is updated with all of the new prices effective January 8.

Our next scheduled update is March 2.

A Calculated Success

Our online Rate Calculator helped add up a successful implementation of new prices. The calculator hosted 536,110 visitors on January 9 ― setting a record for the most visitors to the calculator during a single day. And, with over 8 million visitors during the month of December, it’s proving to be one of our most-used online tools. It can calculate retail, business, and international postage rates.
