Orange County: Apply for Post Office Box Service Today

Orange County residents can apply for Post Office Box™ service from the United States Postal Service (USPS) for secure and convenient mail reception. The USPS offers various box sizes to accommodate different mail volumes for residents throughout the county.

To apply, individuals must present two forms of valid identification. One ID must include a photograph, and the other must prove a physical address. Both documents must be current at the time of application.

Acceptable photo identification includes a valid driver’s license or state non-driver’s identification card, armed forces, government, university, or recognized corporate identification card, passport, passport card, alien registration card, or certificate of naturalization. A second, non-photo ID is required to establish proof of address.

Applicants must list all adults who will receive mail at the PO Box. For personal use, each listed adult must present two forms of valid identification. For business or organizational use, each person listed must present two forms of valid identification upon request. Parents or guardians can receive mail for minors by listing their names; minors do not need to provide identification.

The USPS considers anyone with a key or combination to a PO Box authorized to collect mail. Residents can choose from five box sizes, though availability varies by Post Office location. The smallest box (Size 1) holds 10–15 letter-sized envelopes or up to two rolled magazines. A Size 2 box is recommended for more than 15 mailpieces weekly. Sizes 3, 4, or 5 accommodate larger volumes, including magazines and catalogs.
