Fullerton, CA

ZIP code 92834 is a PO Box-only postal code serving Fullerton, California, rather than a geographically defined district. As a result, no major physical landmark can be reliably identified as being within the ZIP itself. Fullerton landmarks such as Fullerton College, the Muckenthaler Cultural Center, and the Fullerton Arboretum are elsewhere in the city and use different street-address ZIP codes.
