📖 About this office
The Riverside Main Post Office on Chicago Avenue is one of the busiest USPS facilities in the Inland Empire and serves as a primary passport acceptance location for residents across the eastern side of the city. Situated near the University of California, Riverside campus, this office draws applicants from student communities, faculty, and surrounding residential neighborhoods including Canyon Crest and Orangecrest.
This USPS location offers passport acceptance for new DS-11 applications for both adults and minors. Walk-in hours are available Monday through Friday from 10 a.m. to 3 p.m., while Saturday appointments (10 a.m. to 1 p.m.) must be pre-booked through the USPS scheduling system at tools.usps.com. Bringing complete documentation including proof of citizenship, a valid government-issued photo ID, a completed DS-11 form in black ink, and a passport photo is required at the time of acceptance.
Riverside is the county seat of Riverside County and the largest city in the Inland Empire, making this main post office a high-volume acceptance site. For time-sensitive travel needs, the Los Angeles Passport Agency at 11000 Wilshire Blvd in West LA is the nearest full passport agency, roughly 55 miles west via I-10 or CA-60.
