A Mailing Address for AI Agents
Agents can already spend money. Now they can receive mail.
An agent can incorporate a company, open accounts, and move money in seconds. Then the physical world catches up — and a lot of what a business actually runs on still arrives on paper.
The atoms-to-bits problem
Software agents live entirely in bits, but the systems they operate inside were built for people with mailboxes. Form an LLC and the state mails a stamped filing. A bank sends a debit card and a signature card. The Franchise Tax Board, the IRS, a landlord, a vendor — they send checks, notices, and legal documents to a street address, on a schedule no API controls. An agent that can do everything online still can't sign for a certified letter or deposit a paper check. That gap — atoms arriving where only bits can reach — is the last thing standing between an agent and running a real business end to end.
How it works at Postely
Postely gives the agent's principal a real, staffed street address in Santa Monica and turns everything that arrives there into structured data an agent can use.
- The account owner — a person or a business — verifies their identity and signs USPS Form 1583, the authorization that lets a CMRA (commercial mail receiving agency) accept mail on their behalf.
- The agent operates the mailbox under that authority, with access you scope to it — read-only, act-on-mail, or trigger forwards and deposits.
- Every envelope, letter, and document is scanned to structured data: sender, type, dates, and full contents an agent can parse and act on — pay it, file it, flag it, or forward it.
- Junk is filtered by rules you set, so an agent only sees mail that matters.
- Packages and certified mail are received in person at a staffed Santa Monica address — signed for, logged, and available to hold, forward, or deposit.
The result is a physical address for AI agents that behaves like the rest of their stack: programmable, filtered, and always on. The paper comes in; clean, structured data goes out. For the human or company behind the agent, it's a mailbox that finally speaks the agent's language — a mailbox for AI agents without giving up the legitimacy of a real CMRA on the public record.
Available now — and what's coming
Two plans are open today for the agent's principal: Postely Virtual at $25/mo for mail scanning and a real address, and Postely Business at $45/mo with a prestige business address, check deposit, and California registered agent included. Both give you the AI agent mailing address and the structured data feed today. Coming with launch: a direct mail API, so tools and assistants can receive mail and read structured data programmatically — no dashboard in the loop.

Common questions
Can an AI agent have a mailing address?
An agent can operate a mailing address, but the address is legally held by a person or business — the agent's principal. That owner verifies identity and signs USPS Form 1583 to authorize a CMRA to receive mail on their behalf. The agent then operates the box under that authority: reading scanned mail, acting on it, and triggering forwards or deposits within the access you scope to it.
Who signs Form 1583?
The account owner — the human or the business the agent works for. USPS Form 1583 requires a verified identity behind every commercial mail receiving agency box, so an autonomous agent can't sign it alone. Once the principal is verified and the form is on file, the agent operates the mailbox under that person's or company's authority.
Can my agent read and act on the mail?
Yes. Every envelope and document is scanned and delivered as structured data, so an agent can parse it, classify it, and act — pay an invoice, file a notice, flag a legal document, or forward a package. Junk is filtered by rules you set. Direct API access for tools and assistants ships with launch.
Do you integrate with agent-mail platforms?
Postely is designed to work alongside agent-mail and inbox platforms rather than replace them — a real physical address and CMRA behind the digital layer your agent already uses. Direct API access for your own tools and assistants ships with launch.
Why a Santa Monica address?
It's a real, staffed street address in a recognizable California city — not a PO box or a virtual token. That matters for LLC filings, bank accounts, and payment processors that reject mailbox-style addresses, and it gives an agent-run business a legitimate front door on the public record.
