Postal PO Box
Company Overview
A USPS PO Box is a low-cost, secure mailbox located at a U.S. Post Office. Some locations offer a 'Street Addressing' option that provides a real street address rather than a PO Box number. It is best for people who can collect mail in person.

Mailing Address vs. Legal Domicile
A PO Box is not a residential address and does not establish legal domicile or state residency.
Mailing addresses, virtual mailboxes, and commercial mailbox addresses do not automatically establish legal domicile or state residency. Users should verify requirements with the appropriate state agencies, tax professionals, financial institutions, and legal advisers.
Before changing your legal domicile, driver's license, voter registration, tax residency, insurance, banking address, or vehicle registration, verify the requirements directly with the relevant government agencies and qualified professionals.
