Virtual Business Address for Your US LLC: USPS Form 1583 Explained

Mailbox and paperwork representing USPS Form 1583 notarization for a virtual business address

A real US business address — for opening a bank account, receiving vendor mail, or listing on your business profile — doesn't come free of paperwork. Any address you get through a Commercial Mail Receiving Agency (CMRA) requires a notarized USPS Form 1583 before your first piece of mail can arrive. This guide covers what the form actually authorizes, how non-resident founders get it notarized from outside the US, and why this virtual address is a completely different thing from your LLC's registered agent.

The most common mix-up: your virtual business address is not your LLC's registered agent address. They are two entirely separate services, and they commonly sit at two different addresses.

What USPS Form 1583 Actually Authorizes

USPS Form 1583 ("Application for Delivery of Mail Through Agent") is the authorization that lets a Commercial Mail Receiving Agency (CMRA) — a private company licensed by the US Postal Service — accept, open, scan, or forward mail addressed to you at its street address. USPS requires every CMRA to keep a notarized Form 1583 on file for each customer receiving mail there, and without one, the agency cannot legally open a single piece of your mail.

Pick a CMRA

Choose a commercial mail receiving agency in the state or city that fits your needs — this address does not have to match your LLC's registered agent state.

Complete Form 1583

Fill in your details and the entity's, then sign it in front of a commissioned notary — in person, at a US embassy/consulate, or via an accepted online notary session.

Submit ID + form to the provider

The CMRA keeps the notarized form and your two IDs on file. Once approved, mail addressed to that street address starts routing to your account.

What the Form Requires

The core requirements are the same no matter which mailbox provider you pick:

RequirementDetails
Notarized signatureForm 1583 must be signed in front of a commissioned notary — in person or, where the provider and state allow it, via an online notary session.
Two forms of IDAt least one must be a government-issued photo ID. A passport satisfies this for non-resident applicants.
Authorized representative (business)A business applicant lists an authorized officer or representative alongside the entity's details.
Filed with the CMRAThe completed, notarized form stays on file with the mail-receiving company — it is not submitted to a USPS post office directly.

Getting It Notarized From Outside the US

This is where most non-resident founders stall: Form 1583 has to be signed in front of a commissioned notary. The good news is that physical presence in the US is no longer mandatory in every case. Many CMRAs now accept a session with a commissioned online notary over a secure video call, and the process typically runs around 10 to 15 minutes. Other founders instead use a notary available at a US embassy or consulate in their home country.

But the fine print — whether a given provider accepts online notarization from a particular state, and whether a foreign notary with an apostille is enough versus requiring a US-commissioned notary — varies by provider and by state. The safest approach: confirm the exact process with your chosen mailbox provider before you start, rather than assuming any notary session will automatically be accepted.

Virtual Address vs. Registered Agent

A registered agent is a legal requirement: Wyoming and Delaware both require every LLC to continuously maintain an agent at a physical address inside the formation state, to receive lawsuits and official state mail. A virtual business address obtained through Form 1583, on the other hand, is a purely practical choice — for day-to-day mail, banking correspondence, and a professional address on your site or business profile — and it is not a substitute for that legal requirement.

In practice, you generally can't use the same virtual address as your registered agent address. Most states require the agent to be available at the listed address during standard business hours to accept service of process in person, an arrangement a mail-scanning CMRA typically isn't set up for. Most founders keep the two separate: a registered agent in the formation state, and a virtual business address in whatever city fits their brand.

FAQ

What exactly does USPS Form 1583 authorize?

Form 1583, "Application for Delivery of Mail Through Agent," authorizes a Commercial Mail Receiving Agency (CMRA) — a private company licensed by USPS — to accept, open, scan, or forward mail addressed to you at that street address. Without a completed and notarized Form 1583 on file, a CMRA cannot legally receive mail on your behalf.

Can a non-resident complete Form 1583 without being in the US?

Yes. The form still requires a notarized signature, but the notary does not have to be physically in the same room in every case — many CMRAs now accept a session with a commissioned online notary, and some non-residents instead use a notary available at a US embassy or consulate. Requirements vary by provider and by the notary's home state, so confirm the exact process with your chosen mailbox provider before you start.

Do I need two forms of ID for Form 1583?

Yes. USPS requires two forms of identification, and at least one must be a government-issued photo ID (a passport works for non-residents). A business applicant also lists an authorized officer or representative on the form.

Is a virtual business address the same as a registered agent?

No — they solve different problems. A registered agent is a legal requirement: every US LLC must continuously maintain one at a physical address in its formation state, to receive lawsuits and official state mail. A virtual business address through a CMRA is a practical choice for handling day-to-day business mail, banking correspondence, and a professional mailing address — it isn't a substitute for the registered agent requirement, and the two commonly sit at two different addresses.

Can I use a virtual business address as my LLC's registered agent address?

Generally no. Most states require the registered agent to be available at the listed address during standard business hours to accept service of process in person, which a mail-scanning CMRA typically isn't set up to do. Treat the registered agent and the virtual mailbox as two separate, complementary services.
