📖 About this office
The Buffalo Post Office Main Office Window at 1200 William Street is the central USPS processing facility for Erie County, situated on the east side of downtown Buffalo between the Fruit Belt and Broadway-Fillmore neighborhoods. As the main hub of Buffalo's postal network, this location maintains a passport acceptance window where applicants can submit new passport applications by appointment.
The William Street facility is a practical choice for applicants on Buffalo's east side or those who find downtown parking challenging. Because it serves as the main post office for the 14240 ZIP code and surrounding areas, it typically has broader appointment availability than smaller branch locations. Residents applying here for the first time should review the Buffalo city passport guide to compare this option with the Erie County Clerk location downtown, which may suit families with children better.
For travelers with genuine travel emergencies—departure within 14 days—the Buffalo Passport Agency at 111 Genesee Street, about 1.5 miles west, is the appropriate resource rather than an acceptance office. The New York State passport offices overview explains the distinction between acceptance facilities and federal agencies.
💡 Good to know
As the main USPS hub for Buffalo, this location often has more appointment slots available than smaller neighborhood branches, especially outside peak travel season. Bring your completed DS-11 application, proof of U.S. citizenship, a valid government-issued photo ID, and a separate check or money order made payable to the U.S. Department of State. Credit and debit cards are not accepted by the State Department for passport fees, though USPS will accept a card for the separate acceptance fee portion.
