US mailing address for LLC non resident owners and Form 1583

Every private mailbox in the United States rests on a two-page USPS form, and a virtual mailbox that scans letters into an app is no exception under the Postal Service’s own rulebook.

For a US mailing address for LLC non resident owners, that form is where the paperwork starts. Its name is PS Form 1583, Application for Delivery of Mail Through Agent.

I read the form, the Domestic Mail Manual sections behind it, the 2023 revision notice and the USPS help page this month, and I compared what each one says about signatures and identity documents. The rules turn out to be wider than a notary stamp.

The signature can be witnessed by the mailbox company itself, in person or over live video, or acknowledged before a notary commissioned in the United States. A notary at home does not appear on that list.

That detail matters to an owner in Lisbon or Medellín. The rest of the file comes down to matching names and addresses, and if the form and the IDs disagree, the mailbox company has to refuse the application under the manual’s own words.

What counts as a US mailing address for LLC non resident owners?

Three different addresses get mixed up here: the registered agent’s address the state requires, the mailing address the company uses for post, and the home address of the owner abroad.

The registered agent is a legal post, not a mailbox. Delaware’s Division of Corporations says an agent must “maintain a street address and office located in Delaware and be open during normal business hours for the purpose of accepting service of process”.

Its published list of agents carries a pair of warnings. The state says it does not regulate the agents on the list, and it says the chosen agent must consent to the appointment before the filing goes in.

The mailing address is the one the IRS, banks and clients write to. The IRS page on its change form says: “Use Form 8822-B to notify the Internal Revenue Service if you changed” the business mailing address, the business location or the responsible party.

Federal forms ask for it in other places too. FinCEN’s FBAR instructions tell an entity to enter its United States mailing address, and a foreign mailing address only when the entity has no US one.

A private mailbox is one way to have that address. The Postal Service calls the business behind it a Commercial Mail Receiving Agency, or CMRA, and regulates it through section 508 of the Domestic Mail Manual.

Is a virtual mailbox for LLC owners a CMRA?

A virtual mailbox for LLC owners counts as a CMRA when it receives mail for customers and forwards or scans it, and the manual’s definitions make that plain.

The manual defines a CMRA as a business that, in whole or in part, accepts the delivery of US mail “on behalf of another person or entity as a business service”.

Office business centres and reshipping services fall under the same rules.

The revision notice the Postal Bulletin published in 2023 spelled out the digital case, in a list of businesses that must register as CMRAs and follow the same rules. It covers a service that “accepts delivery of mail on behalf of another for the purpose of reshipping or redelivering that mail physically or electronically”.

Scanning has its own line in the paperwork. The customer gives a remail address on the form, or an email address if correspondence is scanned for digital delivery, and the CMRA enters that address in the USPS database.

Each CMRA registers with the Post Office as well. Its owner files PS Form 1583-A with the postmaster, shows two current IDs, and signs for a copy of the manual’s CMRA rules.

The basic service is simple in the manual’s words: “The CMRA accepts delivery of the mail and holds it for pickup or remails it to the addressee, prepaid with new postage”.

A CMRA also carries reporting duties of its own. It uploads each customer’s form and ID copies to the USPS CMRA Customer Registration Database and certifies every quarter that the forms are current and that no ID has expired.

Lawful use is a condition of the box itself. The manual says: “A Private Mail Box (PMB) must not be used for, or in connection with, a scheme or enterprise that violates any federal, state, or local law”.

What does USPS Form 1583 ask for?

USPS Form 1583 asks for the mailbox details, the applicant’s identity and home address, the business behind the box and two identity documents.

An LLC ticks business or organization use. That choice brings in a separate block for the company, with its name, its type of business, its street address, a phone number and its place of registration.

Registration has a precise meaning on the form. The footnote defines the place of registration as the county and state for a domestic registration, or the country for a foreign one, so a Wyoming LLC gives a Wyoming county.

The applicant’s own home address sits in another block, with a country field. A home in Portugal or Brazil fits the form as printed.

An authorized individual can be added to collect mail. That person needs the same two kinds of ID, and for business use every member named to receive mail must show two forms of valid ID to the Postal Service on request.

A separate block on the form covers forwarding. It is filled in when mail addressed to the box is to be transferred, mailed, shipped or emailed to another address, and it asks for that address with its country.

An officer signs for a business and adds a title. The certification under that signature warns that false or misleading answers can bring criminal and civil penalties, including fines and imprisonment.

Verification by the Postal Service can follow the signature. The form says the application may be checked to confirm that the applicant lives or does business at the address given and that the IDs are valid.

Which IDs work for an owner living abroad?

A foreign passport works as the photo ID, because the manual lists it among the acceptable primary forms of identification. Its text reads: “This includes a U.S. passport, U.S. passport card, or foreign passport”.

The USPS help page sums up the count: “Two forms of ID (one with a photo) are required when applying for a Private Mail Box”.

The second document has to prove the home address on the form. The manual accepts another primary ID for that, or a current lease, mortgage or deed of trust, a voter or vehicle registration card, a home or vehicle insurance policy, or Form I-94.

Several familiar papers are refused outright by the manual. It says “the Postal Service does not accept Social Security cards, birth certificates, credit cards, and other similar items as primary or secondary forms of identification”.

A driver’s licence can serve as only one of the two IDs. The form’s footnote allows it as the photo ID or the address ID, not both.

Every document must be current, and names and addresses must line up. The manual is direct about a mismatch: “If information on the application does not match the identification, the CMRA must deny the application”.

Clear copies matter as much as valid ones. The manual treats any expired, illegible or unclear document in the database as out of compliance, and a CMRA told that an image is unclear has to collect a replacement.

My reading is that a lease from Lisbon in the owner’s name can serve as the address proof, since the manual names a lease without limiting it to US property.

Does the form need a notary?

No, a notary is only one way to complete the signature, and the manual sets out both options in the same sentence.

The applicant can sign or confirm the signature in front of the CMRA owner, the manager or an authorized employee, physically or over real-time audio and video.

The other route runs through a notary public. The manual limits it to “a notary public commissioned in a United States state, territory, possession, or the District of Columbia”.

Live video works on the notary route too. The manual allows the acknowledgement in the virtual presence of that notary, in real-time audio and video, so the applicant does not have to travel for it.

Read literally, a notary commissioned in Italy or Mexico is not on that list.

The form’s second page carries a notary box for the state, the county and the date. After signing, the agent uploads the signed form to the USPS database and keeps a copy at its business location, open to examination by the Postal Service and its inspectors.

The witness rule changed over time. The 2023 revision notice spoke only of a CMRA witness or a notary, and the current manual adds the live video option. The form on the USPS site carries a June 2024 date.

How must the mailbox address be written?

Any US mailing address for LLC non resident owners at a CMRA needs PMB or the pound sign before the box number, because the manual requires a CMRA to mark the private mailbox in every delivery address.

The preferred format in the manual has four lines. They hold the name, the box number, the street address, then the city, state and ZIP Code, and a three-line version puts the box number on the street line instead.

Combining a suite number with the box number is not allowed. When the CMRA’s own address already has a suite, the customer has to use PMB in the three-line format.

Mail without the box marker can be returned to its sender.

I would keep one written form of that address. The same spelling then goes on the IRS file, the bank profile and every other filing that asks for a mailing address, so that no office sees two versions of one box.

What happens when details change or the mailbox closes?

A change in any detail means a new form, and the manual says: “When any information required on PS Form 1583 changes, the addressee must complete a new application with the CMRA”.

Closing a mailbox has its own set of rules. Neither the customer nor the CMRA may file a change-of-address order with the Post Office when the relationship ends, and the CMRA keeps the endorsed forms for at least six months afterwards.

The Postal Service’s help page adds a limit on forwarding: “Mail can be forwarded to a CMRA, but not from a CMRA”.

Forwarding after closure becomes the CMRA’s job for a while. The page says “The CMRA is responsible for forwarding their customers’ mail for 6 months following PMB termination”.

Registered Mail is the exception on that page. The customer must go to the local Post Office to accept it, and a CMRA may accept other accountable mail.

That rule matters for an owner an ocean away.

A CMRA’s own compliance also affects its customers. The manual lets the Postal Service suspend a CMRA that breaks the rules, gives it thirty days to comply, and returns mail to senders marked as suspended if it fails.

The Chief Postal Inspector can also order mail withheld from a single box suspected of use in crimes under Title 18 or Title 39 of the US Code. The CMRA then hands that mail back to the Post Office the next business day.

The agreement on the form’s second page splits other duties. Customer and agent are jointly responsible for transferring mail to another address, every piece put back into the mail needs new postage, and the agent reports every transfer address to the Postal Service.

Some services refuse a mailbox address for certain fields. Wise, for one, says a business trading address cannot be a PO box, a mail forwarding service or a virtual office. A mailbox carries mail; it is not a place of business.

What do the USPS pages leave open?

Leases are named as address proof in the manual, without a word on whether a foreign lease in another language qualifies, and I cannot tell how each CMRA treats one.

Prices are another blank in the official pages. The help page says customers pay the CMRA’s own charges, and the official pages I read publish no price for a box.

I have not found a USPS rule on how fast a CMRA must scan or forward mail.

Privacy has only a partial answer in the form. Its privacy statement allows disclosure that an address belongs to an agent, but it says this use does not authorize disclosing who receives mail there.

Before signing up, an owner can ask the mailbox company which witness route it offers, and check with the state office or a US lawyer which address belongs on each filing.

My view is that a US mailing address for LLC non resident owners works well through a CMRA, as long as the owner treats Form 1583 as an identity filing rather than a sign-up form. The next filing that touches this address is the IRS change form, needed whenever the mailing address moves.
