Your LLC is asked for an address by the state, the IRS, your bank, and every platform you sell on. They are not all asking for the same one. This page shows what each asks for, and gives your LLC a US street address with mail handling, from $16.58/mo billed yearly.
A form rarely asks for “your address.” It asks for a specific one, and the line for a street address often has different rules from the line for mail. These are the lines most LLC owners meet first. Every row links to the statute or the official form.
Filed once, when the business applies for an Employer Identification Number.

The Secretary of State's FAQ adds, in its own words: "Post office boxes, drop boxes, virtual addresses, mail forwarding locations, UPS or FedEx stores do not qualify as an acceptable registered office address." That sentence is agency guidance about the registered office. It is not in the statute.

New York, Texas, D.C., and corporation filings are on the full table: address fields on state business filings.
A numbered box at a Post Office. Mailing lines usually take it. Street-address lines usually do not.
A street address, so it fits street-address lines. On filings that are open to the public, it becomes part of the public record.
A street address at a commercial building where mail is received for your business. This is what save office provides.
USPS keeps its own record for every address: commercial or residential, and whether it is registered as a commercial mail receiving agency. You do not have to take a provider's word for how an address is classified, including ours.
The free checker shows the USPS record for any US address, including ours and the one you use today. Run it before you sign up for anything.
An LLC names a registered agent, and the agent has an address. That address exists for one job: receiving legal papers for the company. Many founders end up using it for the IRS, the bank, and invoices too, because it was the only US address on hand.
“A registered agent may not perform its duties or functions solely through the use of a virtual office, the retention by the agent of a mail forwarding service, or both.”
That is Delaware's rule for agents. It is about who can be an agent, and it is one reason the two roles stay separate. save office does not sell registered agent service. Your agent stays where it is, and the business gets its own address.

Comparing providers? How to choose a virtual business address for an LLC.
A government agency or bank may deny your registration or account because of the address or documents we provided. If that happens, email us the written denial letter within 30 days. We'll refund 100% of what you paid for that address.
Some lines on its paperwork do. California's Form LLC-12 says the principal office address "must be a physical address" and does not take a P.O. Box, while the mailing address line on the same form does. The IRS Form SS-4 street address line does not take a P.O. box either. The tables on this page show which line asks for which.
No. A P.O. Box is a numbered box at a Post Office. A virtual business address is a street address at a commercial building where mail is received for your business. Lines that say "no P.O. Box" are asking for a street address.
It is a real US commercial street address, not a PO box — and you can verify how USPS classifies any of our addresses with our free checker. Approval is always each provider's own decision, so no address service can honestly promise it. What we offer instead is a guarantee: if a bank or government agency denies you because of the address we provided, we refund 100% of what you paid for that address.
Yes. Moving to a new business address does not touch the LLC itself. You update the address with the IRS (Form 8822-B), your bank, and your state — paperwork, not a re-formation.
No. save office provides your business and mailing address. Your registered agent is a separate legal role, and it stays as-is — doing the one job it is actually built for.
