USPS Form 1583 Notarization: How to Get It Done Online
USPS Form 1583 notarization, in person or remotely, is one of three ways to verify the form; the other two are the physical presence of the CMRA agent and the agent's virtual presence over real-time video.
The only publicly priced online notary option found for this page is iPostal1's partner Proof, which charges a $25 notarization fee. Checked September 26, 2026

How online notarization works, step by step
- Pre-fill the form. Fill out the USPS Form 1583 PDF with the applicant's and any authorized individuals' details before starting the notary session.
- Gather two forms of ID. Have two acceptable forms of ID ready, one a government-issued photo ID, matching the name and address used on the form.
- Start the online notary session. Begin a session with the provider's online notary partner; iPostal1's partner Proof is available 24/7.
- Verify by live video with a notary. Confirm identity over real-time video with a commissioned notary, who acknowledges the signature remotely, consistent with Form 1583's rule allowing acknowledgment before a notary in the applicant's virtual presence.
- Receive the notarized PDF. Proof completes the session in minutes and returns the notarized document.
- Send the notarized form to the provider. Proof states that iPostal1 does not receive a copy of the finalized documents automatically, so the customer must send the notarized form and both IDs to the provider following its own instructions.
These steps assume the applicant has already read how to complete Form 1583 and has a filled-in copy ready; this page covers only the verification and notarization step.
Provider differences
iPostal1 routes online notarization through Proof for a published $25 fee. The customer pays by credit card, completes the session in minutes, and is then responsible for sending the finished, notarized form and IDs to iPostal1 itself, since Proof does not forward it automatically. Anyone weighing that provider can see what iPostal1 costs in practice beyond notarization. Anytime Mailbox advertises online notarization as available 24/7 "for a nominal fee," but does not publish a specific price on its Form 1583 page; it also offers in-person verification, arranged by contacting the specific mail center operator for an appointment rather than through a central booking system, and how Anytime Mailbox location pricing works covers that per-location model in more detail.
Common mistakes
- No Using an unacceptable ID. Anytime Mailbox specifically lists Social Security cards, birth certificates, credit cards, corporate identification cards and utility bills as not acceptable.
- No A name or address mismatch. The name and address on the ID and any secondary document need to match what is entered on Form 1583, or verification can be rejected.
- No Not sending the notarized copy to the provider. An online notary session finishes the notarization, but with iPostal1's Proof option the customer still has to send the notarized form and IDs to the provider afterward, or the mailbox account stays unauthorized.
What this means for choosing a provider
The verification step is the same three routes everywhere, but the notarization fee, availability and follow-up steps differ by provider. Anyone still deciding on a provider can compare virtual mailbox providers side by side, and anyone who already has a plan and just needs the address itself can read the Virtual Business Address guide.
FAQ
How much does it cost to get USPS Form 1583 notarized?
The USPS form itself carries no filing fee. The only published online notary price found for this page is iPostal1's partner Proof at $25. Anytime Mailbox describes its online option as "a nominal fee" without publishing a number, and in-person notary costs vary and are not published on a single page.
Does USPS Form 1583 have to be notarized?
No. Notarization is one of three accepted ways to verify the signature. The applicant can also confirm the signature in the physical presence of the CMRA agent, or in the agent's virtual presence over real-time video, without using a notary at all.
Can I complete USPS Form 1583 online?
The form itself can be filled out using the official fillable PDF, and the signature can be verified online too, either through live video with the CMRA agent or through an online notary, instead of an in-person visit.
How long does Form 1583 take to process?
A published processing time was not found for this page. Proof describes its own notarization session as completed in minutes, but that covers only the notarization step, not how long the provider itself takes to activate mail service afterward.
