📖 About this office
The Columbia Main Post Office anchors the east edge of downtown at 511 E Walnut Street, a short walk from the courthouse square and the University of Missouri campus. It is a U.S. Department of State passport acceptance facility, meaning an authorized clerk verifies your identity, witnesses your signature, and forwards your application for processing. It handles first-time adult passports, applications for children, and replacements for lost or damaged books.
Passport service here is handled during posted windows, and scheduling ahead through the USPS system is the smoothest route, especially in the spring and summer rush. It does not take photos on premises, so if you need one, the nearby MU International Center offers that in a single visit. Before arriving, run through what to bring and the fees on the Missouri passport guide.
💡 Good to know
Street parking downtown is metered, with city garages a block or two away. Photos are not offered here, so bring a compliant 2x2 photo, or use the campus acceptance office that provides them. The current fee schedule is posted on the state page.
