The legal requirements, in order
Two separate systems govern this, and conflating them is the single most common mistake.
1. USPS Form 1583 — the federal gate every provider goes through
No US company can legally hand you mail addressed to someone else's commercial address without this form on file. It's not optional, and it's not specific to any one provider — it's a federal requirement tied to the provider's status as a Commercial Mail Receiving Agency (CMRA).
What it actually involves:
- Two forms of ID — one government-issued photo ID, plus a second document confirming your home address
- Notarization — you sign in front of a notary, who verifies your identity and witnesses the signature; some providers now offer remote online notarization instead of an in-person visit
- It authorizes the provider to receive and handle your mail — it does not itself forward or reroute anything; that's a separate instruction you give the provider afterward
- Since a 2023 USPS update, spouses each need their own separate Form 1583 — one form can no longer cover both
2. Registered agent — a completely different legal role
This is the part that catches non-resident founders off guard: your virtual mailing address and your registered agent address are not allowed to be the same kind of thing, even though both are "an address for the business."
| Registered agent | Virtual / commercial address |
|---|
| Legally required for every LLC and corporation |
Optional — a business choice, not a filing requirement |
| Must be a physical street address in the state of formation, staffed during business hours |
Can be anywhere, staffed by a mail-handling provider rather than a person waiting for service of process |
| Receives lawsuits and official state notices |
Receives everyday mail — invoices, bank correspondence, general business post |
| Not meant to be your public-facing business address |
The address you'd put on your website, invoices, and marketing |
Most states — Wyoming and Delaware explicitly among them — spell out that a P.O. box or virtual mailbox cannot serve as the registered office. Some providers bundle a compliant registered-agent service alongside a mail plan; others sell mail-only plans that don't cover this requirement at all. Confirm which one you're buying before you rely on it.
