What is USPS Form 1583 and Why Do You Need It For Your Virtual Mailbox?

November 9, 2022 | 5 min read
The USPS Form 1583 is a requirement to verify your virtual mailbox account. When you sign up for a virtual mailbox, you need to complete the USPS Form 1583, get it notarized, and submit it to the staff at your chosen mail center location. Here’s an in-depth guide to the form—from why you need it to how to fill it out and submit it.
What is USPS Form 1583?
The USPS Form 1583, or the Application for Delivery of Mail Through Agent, is a document that authorizes a Commercial Mail Receiving Agency (CMRA) to receive and handle postal mail on behalf of the customer.
Anytime Mailbox partners with mail business centers and coworking locations that are approved CMRAs. This ensures that your postal mail and packages are secure and handled by staff authorized by USPS.
Why You Need to Complete the USPS Form 1583
The USPS Form 1583 grants the CMRA of your choice permission to receive and handle postal mail for you. The USPS requires anyone who rents a P.O. Box, a mailing address, or a virtual mailbox from a third-party location to fill out and submit a notarized copy of the form.
When you sign up for an Anytime Mailbox virtual mailbox, the CMRA staff at your chosen location will handle your postal mail and packages. The USPS Form 1583 gives them authority to do so on your behalf.
The form also helps the operator at your selected location verify the identity of all their virtual mailbox renters. This ensures that only you access your postal mail and packages.
It’s important to note that without the completed USPS Form 1583 on file, the operator at your selected location cannot receive your postal mail or packages and will mark it “RTS” (Return To Sender), sending it back to the Post Office.

2. Notarize the Form
US Postmaster General regulations require the CMRA handling a mailbox renter’s mail to have a notarized USPS Form 1583 on file for each virtual mailbox renter. Getting the form notarized is non-negotiable and will be checked by the CMRA as they receive the form before your application is thoroughly verified and before the CMRA can receive mail on your behalf.
To notarize your USPS 1583 Form:
Prepare two valid IDs for the notarization process. Most people use a driver’s license and a recent utility bill. Here is a list of acceptable IDs:
  • Valid driver’s license or state non-driver’s identification card
  • A recent utility bill that matches the address on the valid driver’s license
  • Armed forces, government, university, or recognized corporate identification card
  • Passport
  • Alien registration card or certificate of naturalization
  • Current lease, mortgage, or Deed of Trust
  • Voter or vehicle registration card
  • Home or vehicle insurance policy
