You must have a valid Business Reply Mail permit before you can mail. You may apply for a permit at any time by filling out PS Form 3615, Mailing Permit Application and Customer Profile.
Note: PS Form 3615 is a simple form requiring you to know the company name, address where the mail will be returned, contact person, and telephone number. The forms are available at your local Post Office™, Mailing Requirements Office, or Business Mail Entry Unit (BMEU).
A Business Reply Mail permit number is issued at the Post Office where the PS Form 3615 is filed, generally where the mail is returned, and requires a fee. The fee is paid annually by cash, check or money order.
Note: Checks must be made out to the US Postal Service® or Postmaster.
