How Can We Help?
The USPS Form 1583 is a required United States Postal Service document that authorizes a Commercial Mail Receiving Agency (like PhysicalAddress.com) to receive and handle your mail.
Without this completed form, we cannot scan, forward, or upload any mail to your account. Right after you sign up, we email you a pre-filled 1583 form and a link to our online notary, which supports international clients, to help you complete the process easily—even if you’re not in the U.S.
