The US Postal Service has provided forms and instructions online designed to help mailers apply for their Mailer ID, a field within the Intelligent Mail barcode.
Mailers can apply for an ID at their Business Mail Entry Unit (BMEU) or through their local Mailpiece Design Analyst (MDA).
To find the nearest office, mailers can use a postal locator tool at pe.usps.com (click on “postal locator” in the left-hand navigation bar).
