PS Form 1583 and notarization: what the rule actually says

Does Form 1583 need to be notarized?

No. USPS has never made notarization the only route for PS Form 1583. Under the current rule, in force since May 1, 2024, the applicant signs or confirms their signature in front of the mailbox operator's owner, manager or authorized employee, or acknowledges it before a notary commissioned in a US state, territory, possession or the District of Columbia. Either can happen in person or over real-time audio and video. The wording sits in the Domestic Mail Manual, section 508.1.8.3.

Some mailbox providers ask every new customer for a notarized form. That is the provider's own process choice. The USPS rule offers both routes, so a customer who was told "USPS requires a notary" was told something the rule does not say.

Two details trip people up. The staff route needs the operator's owner, manager or an authorized employee, so a friend or coworker watching you sign does not count. The notary route needs a notary with a US commission, so a notary commissioned only in another country does not fit it as written.

What is PS Form 1583, and what is a CMRA?

PS Form 1583 is the Application for Delivery of Mail Through Agent. It authorizes a commercial mail receiving agency (CMRA) to accept mail on someone else's behalf. USPS defines a CMRA as a business that, in whole or in part, accepts delivery of US Mail for another person or entity as a business service. Office business centers and reshipping services count as CMRAs, and a virtual mailbox service that receives mail for its customers as a business service fits the same definition.

The operator's owner or manager completes a Form 1583 about themselves. Beyond that, each addressee of a private mailbox for residential or personal use needs a separate form. Spouses who share a box each sign their own, and a parent or guardian can list minors on theirs. The applicant completes every entry and shows a primary and a secondary form of ID, both current.

The operator does the checking. It confirms the applicant lives or does business at the permanent address on the form, records both IDs on the form, denies the application when the form and the IDs do not match, and uploads a copy of each ID to USPS. It keeps at least a digital copy of every form on site for USPS representatives and inspectors. When a box closes, it writes the closing date on its copy and keeps that copy for at least six months. A new form is required whenever the information on it changes.

For scale, USPS's Inspector General reported over 1.6 million private mailbox customers, through nearly 12,000 CMRAs, as of February 2025. Those are mailbox figures. They say nothing about how many forms get notarized.

Staff witnessing came first: 1973, 1982 and the 2024 wording

The idea that Form 1583 used to need a notary has the history backwards. USPS required the mailbox operator to witness Form 1583 starting in 1973. It first allowed a notary to witness the form in 1982. Staff witnessing is the older route by nine years.

The rule USPS finalized in 2024 kept both routes and settled the wording. USPS had proposed letting applicants 'acknowledge' their signature before mailbox staff. A commenter warned that the word could be read as giving staff notarial authority, so USPS switched to 'confirm' for staff and kept 'acknowledge' for notaries. Its explanation: notaries in the United States are appointed by state governments, and USPS has no authority to confer notarial authority on anyone.

If you sell notarization, read that word choice closely. A staff confirmation is not a notarial act, and mailbox staff do not notarize Form 1583. The same rule also spelled out that the notary on the other route must hold a commission from a US state, territory, possession or the District of Columbia.

Form 1583 over video: what the rule allows and what it leaves out

Both routes can run over real-time audio and video. An operator's owner, manager or authorized employee can watch an applicant sign or confirm on a live call, and the rule lets the applicant acknowledge before a US-commissioned notary on a live call. That is as far as the rule goes.

It names no remote online notarization standard, platform or provider, and it endorses none. Whether a given notary may notarize over video is set by the law of the state that commissioned that notary, not by USPS. Federal e-signature law does not change that. When a law requires a signature or record relating to a transaction in or affecting interstate or foreign commerce to be notarized, the ESIGN Act lets the notary's electronic signature meet that requirement, with the information the law requires attached to or logically associated with it. It covers the electronic signature. It does not by itself let a notary act over video.

USPS has also said it has not prescribed the steps an operator must follow when witnessing Form 1583 in a video session, just as it has not prescribed steps for witnessing in person. So an operator's video process is its own design, and yours is set by your notaries' state law.

For a RON platform, that shapes the pitch. Never tell an operator that USPS approves your platform. What you can offer is a remote session with a commissioned notary, run under that notary's state law, with the identity checks and records that state requires. The guide to selling remote online notarization to businesses has more on pitching RON to business clients.

Quarterly certification and new forms: what they require

Operators certify their customer records with USPS every quarter, due January 15, April 15, July 15 and October 15. They certify that every Form 1583 they submitted is current, that all termination dates are updated and that no ID on file has expired. Nothing in the rule requires a new notarization each quarter.

So do not build a pitch around those dates. The certification is the operator attesting to its own records. The rule ties a new Form 1583 to changed information, not to the calendar, and a new form can go through either route, same as the first one.

Keep your claims narrow here too. A notarized Form 1583 does not satisfy the operator's own duties. Every duty in the rule stays with the operator whichever route the applicant used: checking the IDs and the address, recording them on the form, uploading the ID copies, keeping the forms and certifying each quarter. A pitch that promises compliance falls apart the first time the operator's team reads section 508.1.8.

What a mailbox operator actually buys from a notary business

USPS lets operators run Form 1583 with their own staff, so an outside notary has to earn a place in the signup flow. Operators that pay for notarization are buying some mix of four things. Find out which one matters to the operator in front of you before you quote a price.

• Identity checks by someone outside the operator. A commissioned notary checks ID under their own state's rules, which puts an independent check on who is opening a box.
• Remote convenience for customers abroad or across the country. Where the notary's state allows it, a remote session with a US-commissioned notary lets a customer finish the form without visiting a storefront or booking a call with the operator's staff.
• A record of the signing. Where the notary's state requires a journal entry or a session recording, that record exists alongside the operator's own copy of the form.
• Staff time. Every live confirmation an employee runs is time away from handling mail. Handing the signature step to a notary moves that part out of the building, though the operator still checks and records the IDs.

The first question to ask each mailbox operator

Before you pitch, find out how the operator handles Form 1583 today. Expect one of three answers: staff confirmation in person or by live video, a notary on staff, or a notarization partner built into signup. The answer tells you whether there is anything to sell and what to open with.

You can often see part of the answer before the first call. Walk through the operator's online signup as a customer would, up to the Form 1583 step, and note whether it offers a video call with staff, a notary session or both. Then ask plainly, and ask who owns the signup flow. At a small operator that is typically the owner. At a larger one it is typically an operations or product leader who runs customer onboarding.

Example (invented for illustration): a two-location operator with online signup confirms every form over live video with its own staff. Nothing is broken there. Open with staff time and with the customers who would rather see a notary, and take the no gracefully if their process works. Once you are in, the playbook for turning a first client into repeat notary business applies.

Finding mailbox operators worth a conversation

USPS will not give you a list of operators on request. Its rules bar it from releasing any mailing list or other list of names and addresses in response to a public request, and from disclosing to the public, from Form 1583, whose mail an operator receives. You build your own list.

Industry is a weak filter on its own. Two questions matter more: how many documents a business needs notarized, and whether the people signing them are remote. An operator that signs up customers online, including customers abroad, answers yes to the second question. One that sends every new customer to a notary already has notarization running at the pace it adds customers.
