# Can I use a PO box for a registered agent? *Reviewed 2026-07-29* ## Short answer No, a P.O. box generally cannot be used as a registered agent address. States require a physical street address in the state where a person can accept legal documents in person during business hours. A P.O. box, a mailbox rental, or a virtual mailbox does not meet that standard because there is no one present to receive service of process. The address on file must be a real, staffed location. The purpose of the registered agent address is in-person delivery of legal notices, so states insist on a physical street address rather than a mailing address. A P.O. box or private mailbox forwards mail but has no one available to accept a process server handing over [Service of process](/glossary/service-of-process), which is why those addresses are rejected for this role. Some states will note the distinction explicitly on their forms. If you do not have a suitable street address in a state, or you do not want to publish your home or office address, a [Commercial registered agent](/glossary/commercial-registered-agent) provides a compliant in-state street address and staff to receive documents. That keeps your filing valid and your personal address off the public record. A P.O. box can still be used for general business mail, just not for the registered agent appointment. ## Related - [Registered agent services](/registered-agent-services) - [Can I be my own registered agent](/can-i-be-my-own-registered-agent) - [Who needs a registered agent](/who-needs-a-registered-agent) --- ## How to cite this page Cite as: "Can I use a PO box for a registered agent?."
