MDA Customer Service Help Desk
A new, nationwide MDA Customer Service Help Desk is now available!

The United States Postal Service® is excited to announce the launch of the MDA Customer Service Help Desk, a new service that connects customers directly with a Mailpiece Design Analyst who will provide timely assistance and evaluations of mailpiece design, including Reply Mail. Customers may contact the MDA Customer

Service Help Desk Monday through Friday between 7:00AM and 5:00PM CT by dialing 855-593-6093, or by sending a request via email to mda@usps.gov.

Escalation Process for Mailers
For questions concerning business mail preparation or acceptance, mailers should consult with the local Post Office® or Business Mail Entry Unit where they hold their permits and deposit their mail.

A BME Supervisor or Postmaster can be a good resource for information and assistance. If you have questions regarding mailpiece design, contact your local Mailpiece Design Analyst. You can search by using the Mailpiece Design Analyst Lookup.

The first step in escalating an issue or concern is to contact your District Business Mail Entry Manager. You can search by using the District Business Mail Entry Locator.

If you are unable to resolve your issues, you can escalate to the local District Marketing Manager. Click here for a list of Marketing Managers.

Mailers with Detached Mail Units (DMUs) and/or Special Postage Payment Systems may contact their District Business Mail Entry Manager. If unresolved they should contact their Business Mailer Support (BMS) Analyst. Click here for a list of BMS Analysts.

The next step in the escalation process is the Area Marketing Manager. Click here for a list of Area Marketing Managers.

If you feel that your concerns have not been addressed and you want to escalate it further, prepare an email with the following information:

  • Description of the issue/concern
  • People you have already contacted
  • Results of that contact at each stage of the process

Send the email to MailerSOXConcerns@usps.gov to have your issue addressed at the Headquarters level.
