📖 About this office
The Columbia Main Post Office sits at 1601 Assembly Street in the heart of downtown Columbia, a short walk from the State House and the University of South Carolina campus. As the flagship USPS branch for the capital, it processes a steady flow of passport applications for residents across Richland County and the surrounding Midlands.
Staff here accept and witness applications for first-time adult passports, passports for children, and any renewal that must be submitted in person (for example, a lost, damaged, or long-expired book). Because this is downtown Columbia's busiest window, appointment slots fill quickly around spring break and early summer, so booking ahead is worth the effort.
Passport photos are taken on site, so you can complete photo and application in a single visit. If this location is fully booked, other Columbia acceptance offices can often fit you in sooner.
💡 Good to know
Downtown parking is metered and can be tight during State House business hours, so leave a few extra minutes. Bring your completed DS-11, proof of citizenship, a photo ID plus a photocopy of it, and separate payments for the application and the acceptance fee.
