What it is
USPS Form 1583 — the Application for Delivery of Mail Through Agent — authorizes a Commercial Mail Receiving Agency (CMRA) or virtual mailbox provider to receive mail on your behalf. The Postal Service requires the form to be notarized before the agent can accept your mail.
Who needs it
Remote workers and travelers using a virtual mailbox, small businesses setting up a professional street address, or anyone signing up with a mailbox or mail-forwarding service.
Why it needs a notary
USPS regulations require Form 1583 to be notarized so the mail agent can verify the identity of the person authorizing mail delivery. Without notarization, the CMRA cannot legally receive your mail.

Frequently asked questions
- Will my mailbox provider accept an online-notarized Form 1583?
- Yes. USPS explicitly permits Form 1583 to be notarized remotely, and virtual mailbox providers accept the electronically notarized PDF. You'll typically need to provide two forms of ID — our notary verifies both during the session.
- What two IDs does Form 1583 require?
- USPS requires one photo ID (like a driver's license or passport) and one address-verifying document (such as a vehicle registration, lease, or utility bill). Have both ready to show on camera.
- How fast can I get it done?
- Notaries are available 24/7 and most Form 1583 sessions finish in about 15 minutes, so you can usually activate your mailbox the same day.
