Passport offices in Diamond Bar, CA

Every listing above is an official passport acceptance facility in Diamond Bar — post offices, clerks of court, public libraries, and other government offices authorized to review your documents, witness your signature, and seal your DS-11 application packet for the U.S. Department of State. First-time applicants, minors under 16, and anyone replacing a lost, stolen, or damaged passport must apply in person at one of these Diamond Bar locations; most adult renewals can skip the visit entirely and apply by mail.

None of the Diamond Bar listings currently publish on-site photo service, so plan to bring a compliant 2×2 inch passport photo — our free photo tool makes one from your phone in minutes. Appointments are required or strongly recommended at every listed location — book ahead before you go. Always bring proof of U.S. citizenship, a photo ID, and payment for both the State Department fee and the facility's $35 execution fee.

If you are traveling within 14 days (or 28 for a foreign visa), an acceptance facility is not enough — you will need an appointment at a regional passport agency. Our California page lists the nearest options, and each Diamond Bar listing links to directions, live hours, and the busiest and quietest times to visit.
