When you sign up for a virtual mailbox, rent a PO Box, or authorize someone else to receive your mail, the United States Postal Service (USPS) requires you to submit PS Form 1583. This form authorizes the receiving agency to handle your mail. However, to ensure the request is legitimate, USPS mandates that the form be notarized if you’re not submitting it in person.
Not sure how to notarize the USPS form? This guide walks you through the steps.
What Is USPS Form 1583?
USPS Form 1583 is an official document that gives permission to a third party, usually a Commercial Mail Receiving Agency (CMRA), to receive mail on your behalf. It’s a legal safeguard against mail fraud and unauthorized handling.
This form is typically required when you use:
A virtual mailbox service
A business mail forwarding service
A private mail center (e.g., UPS Store)
Why Notarization Is Required
When submitting PS Form 1583 remotely (not in person), USPS requires that your identity be verified by a notary. This prevents fraud and ensures that you are indeed authorizing the service to manage your mail.
Step-by-Step: How to Notarize USPS Form 1583
1. Fill Out the Form

Complete the form but do not sign it yet—you must sign it in front of a notary. Here’s what to fill in:
Your name and address
The address of the mail receiving agency (they usually provide this)
Two forms of acceptable ID (like a driver’s license and passport)
Business name (if applicable)
2. Gather Identification
USPS requires two forms of ID. Acceptable forms include:
Primary ID: Government-issued photo ID (driver’s license, passport, state ID)
Secondary ID: Utility bill, lease, vehicle registration, etc.
Make sure both IDs are current and valid.
3. Find a Notary
Options include:
Local Notary: Check banks, shipping centers (like UPS), or law offices.
Online Notary: Many virtual mailbox services accept online notarizations using services like Notarize.com or NotaryCam.
Online notarization is legal and accepted for PS Form 1583 in most states and by most CMRAs—always confirm with the mail service provider first.
4. Attend the Notary Session
Bring or upload:
Your completed PS Form 1583 (unsigned)
Your two forms of ID
Any additional documents your CMRA requires
Sign the form in front of the notary. The notary will:
Confirm your identity
Watch you sign
Stamp and seal the form
5. Submit the Notarized Form
Once notarized:
Scan or take a clear photo of the completed form
Send it to your CMRA or upload it through their platform
They’ll then submit it to USPS as required.
Tips & Reminders
Double-check the form for errors before notarizing.
The notary seal/stamp must be legible and include the commission number.
Some services include notarization in their setup process—ask first.
If you’re outside the U.S., many virtual notary services can still help you get it done remotely.
