It is not a requirement that you live in the state where you rent a post office box. PO Box service is optional in most areas, which is why there is a fee to cover the cost of providing the service, as opposed to receiving free street delivery. I worked for several years at two post offices in resort cities. Many of our post office box customers live in other states and rent or own vacation properties in our area. While they are not in town, a temporary forwarding order closes the box for delivery and it is cancelled when they return.You may use an out of state ID to rent a PO Box if it is recognizable and valid. Actually, two forms of ID are required and one must have a photo. Acceptable forms of photo ID include: a current driver's license or state ID card, a military, government, university or recognized corporate ID, a passport, alien registration card or certificate of naturalization.You also need to prove your physical residence to rent a PO Box. That can be accomplished by providing a current lease, property mortgage or deed, utility bill, or a PO Box application which has been approved and postmarked by your home post office.
