📖 About this office
The Arnold Post Office on Jeffco Boulevard is the primary federal mail facility serving Arnold and the surrounding Jefferson County communities. Situated along one of Arnold's main commercial corridors, this post office offers passport acceptance services by appointment for first-time applicants, children, and those replacing lost or stolen documents.
Residents of Arnold, Barnhart, and nearby Jefferson County zip codes rely on this location as their most accessible federal option for in-person passport processing. The acceptance agent reviews your DS-11 application, verifies identity documents, witnesses your signature, and forwards the package to the National Passport Processing Center.
Appointments are scheduled through the USPS online passport appointment system. Bring a completed (but unsigned) DS-11 form, proof of citizenship, a valid photo ID, a passport photo, and the applicable government fees. The office can accept payment for the acceptance fee; passport execution fees are paid separately to the U.S. Department of State.
