USPS Form 1583: Getting a Virtual Mailbox Notarized

Every virtual mailbox or CMRA needs a completed PS Form 1583 on file — and notarization is the universally accepted way to verify identity. The two-ID rule, the 2023 form changes, and the ten-minute online process.

Why your mailbox is stuck on a form

Any commercial mail receiving agency (CMRA) — which includes every virtual mailbox service and most mailbox stores — must keep a completed PS Form 1583 on file before it can legally receive your mail. It's a USPS requirement (Domestic Mail Manual 508), and the form is your authorization for the CMRA to accept mail on your behalf.

Because the form delegates control of your mail, USPS requires your identity to be verified. That verification step is the reason your new virtual mailbox says "pending" — and it's usually a ten-minute fix.

The 2023 revision, and what it means for you

USPS overhauled its CMRA rules and the form itself in 2023. Under the current rules, identity can be verified either by the CMRA itself — in person or through an approved remote process — or by a notary. In practice, many virtual mailbox providers still route customers to the notarized path: it's the universally accepted option and the simplest for providers to keep on file.

Follow your provider's instructions. They'll usually pre-fill their own section of the form — the CMRA's name, address, and registration details — and tell you exactly which verification path they accept.

The two-ID rule

Form 1583 requires two forms of identification, and this is where most first attempts fail:

  1. One photo ID

    Driver's license, state ID card, passport, or similar government-issued photo identification.

  2. One address ID

    A document tying you to your home address: a lease or deed, voter or vehicle registration, or a current insurance policy. The acceptable list is printed on the form itself.

  3. Complete the form, but don't sign

    Your section filled in, the CMRA's section from your provider, and the signature saved for the camera — the notary must watch you sign.

The online session and the handoff

The session is quick even by online-notarization standards: identity verification, a short recorded video call with a commissioned notary, sign on camera, sealed PDF immediately. On our price list a PS Form 1583 is $39, itemized like everything else. Online notarization is available to signers in most states — check yours on the state availability grid.

Delivery is the easy part: virtually all mailbox providers accept the sealed PDF uploaded to their portal or sent by email — no printing, no shipping. If yours wants paper, we can print and mail it with tracking.

Opening the box for an LLC or a team? The form covers business applicants too — the business's information plus the people authorized to receive its mail. Your provider will tell you who needs to be listed, and each authorized recipient can verify and sign.

QUESTIONS

Asked before every order

Does USPS require notarization for Form 1583?

Notarization is one accepted verification path under the post-2023 rules; CMRAs can also verify identity themselves in person or through approved remote processes. Your mailbox provider decides which paths they support — many still require the notarized form, so follow their instructions.

What IDs do I need for Form 1583?

Two: a government-issued photo ID, plus a second document that verifies your home address — a lease, deed, voter registration, vehicle registration, or current insurance policy. The form lists the acceptable types; the same IDs are shown to the notary and recorded on the form.

Do I need to mail anything after the notarization?

Usually not. Providers overwhelmingly accept the electronically sealed PDF through their onboarding portal or by email. Print-and-mail with tracking is available if your provider is the exception.

Can I notarize 1583s for my whole team?

Yes — each person authorized to receive the business's mail verifies their identity and signs. Additional signers are $25 each in the same order, with every fee itemized before you pay.
