If youโ€™re signing up for a virtual mailbox or mail forwarding service in the United States, youโ€™ve probably been asked to submit USPS Form 1583. But what exactly is this form, and why does it need to be notarized?

What is USPS Form 1583?

USPS Form 1583 is required by the United States Postal Service to authorize a third party (like a virtual mailbox provider) to receive your mail on your behalf. It protects against identity theft and ensures only authorized parties can manage your postal correspondence.

Why Does Form 1583 Require Notarization?

To verify your identity and authority, the USPS requires either:

  • A personal appearance at the virtual mailbox providerโ€™s office with two forms of ID, or
  • A notarized copy of the completed Form 1583.

This makes the form legally binding and acceptable by the USPS.

Step-by-Step: How to Notarize Form 1583

  1. Fill Out the Form Completely Include your name, business name (if applicable), address, and the address of the CMRA (Commercial Mail Receiving Agency).
  2. Choose Your IDs Youโ€™ll need two valid forms of ID. One must be a photo ID (like a passport or driverโ€™s license). Acceptable second forms include utility bills, lease agreements, or insurance cards.
  3. Do NOT Sign the Form Yet Wait to sign Form 1583 in front of a notary public.
  4. Connect with a Notary You can use an online notary (Remote Online Notarization, or RON) to get this done from anywhere โ€” even if youโ€™re overseas.
  5. Complete the Notarization The notary will verify your identity, watch you sign the form, and apply their stamp and signature.
  6. Submit to Your Mailbox Provider Send the notarized form and scanned copies of your two IDs to your provider. Youโ€™re good to go!

Can You Notarize Form 1583 Online?

Yes! Thanks to federal laws (like the ESIGN Act), many states now allow Remote Online Notarization (RON), which lets you notarize from your laptop or phone โ€” no matter where you are in the world.

Online notarization is especially helpful for:

  • Digital nomads
  • Non-U.S. residents
  • People too busy to visit a notary in person

Final Tips

  • Double-check the virtual mailbox providerโ€™s instructions โ€” some require specific formatting.
  • Make sure your IDs are not expired.
  • Use a reliable, USPS-compliant notary platform.
