When renting a PO Box, the customer is typically assigned two keys. This is a standard practice established by the USPS to ensure that customers have adequate access to their box while also providing a level of security. The two keys allow for one to be a primary key for the renter, and the second can serve as a backup or be given to someone the customer trusts, facilitating easy access without compromising security.

Having two keys not only helps in case one key is lost but also provides flexibility for customers who may wish to share access to their mail. It reflects the USPS's commitment to customer convenience and security in their postal services.
