Fullerton Main Post Office

The Fullerton Main Post Office on East Chapman Avenue has served as the city's primary federal mail facility for decades, and its passport acceptance counter is one of the busiest in northern Orange County. Situated just west of the 57 Freeway, it draws applicants from Fullerton's university neighborhoods, downtown workers, and families across the eastern zip codes.

First-time adult applicants and parents applying for minor passports can schedule appointments here through the USPS online tool. The office witnesses and seals your completed DS-11 form, verifies your identity documents, and forwards the sealed packet directly to a State Department processing center — a clean chain of custody with no intermediate stops.

If you need to escalate to an urgent appointment at the Los Angeles Passport Agency, this office's sealed application gives you the required documentation. Explore all acceptance options in Orange County on our Fullerton passport guide.

The Chapman Avenue address sits in the 92834 postal zone, but the office serves applicants from across Fullerton's zip codes. Bring two forms of ID, your certified birth certificate (original, not a copy), and a completed DS-11 form — but do not sign it until you are in front of the acceptance agent. Payment for State Department fees is separate from any USPS service fees. For context on statewide processing options, our California passport guide covers agency locations, expedited timelines, and what to expect.
