The best way to contact the United States Postmaster General is to send a letter addressed specifically to him through the mail. You can send an email using a form on the United States Postal Service, or USPS, website, but that gets routed according to the topic you select in the drop-down menu. The only telephone number available to the public is the general USPS toll-free number, 1-800-ASK-USPS — not a direct line to the Postmaster General.
Addressing the Postmaster General
Mail your correspondence to: Postmaster General, United States Postal Service, 475 L’Enfant Plaza SW, Washington DC 20260-0010. To be proper, you should write “The Honorable” and then the full name of the current Postmaster General on the top line, and use “Postmaster General” as the title on the line below his name. On your correspondence, use “Dear Mr./Madam Postmaster General” in your salutation.
The 2014 USPS email contact form requires that you select a contact reason: Information, Problem, Suggestion or Compliment. After your selection, sub-categories appear and you narrow your issue more — for example, sending or receiving mail. Then write about your issue in more detail and send. If this form changes, it’s still a good idea to have a clear subject in your email. If it’s important or serious enough it is more likely to go the Postmaster General than if it’s just a mail delivery issue at your local post office.
The 2014 USPS phone system uses voice recognition to identify the issue and then route your call accordingly. Speaking to the Postmaster General is not one of the available options, but you can leave a message that you’re trying to reach him or her with the Customer Service department. Remember that USPS recognizes federal holidays.
