📖 About this office
The Bay St. Louis Main Post Office anchors the retail postal counter on Highway 90 and doubles as the city's most convenient passport acceptance point. Applications for new adult and child passports are handled by appointment, and the branch takes the required 2x2 photo in-house, so a first-timer can arrive with paperwork and leave with the whole packet witnessed and sealed. It is the everyday choice for most residents applying alongside other Bay St. Louis errands.
As a USPS acceptance facility it verifies your identity, witnesses the DS-11 signature and mails the application to a federal center; it does not print the passport itself. Appointments are booked through the USPS scheduler rather than by walking in, and photo service is available on the same visit. Before you come in, look over the statewide fee and document details on the Mississippi passport guide.
💡 Good to know
Book the passport slot through the USPS online scheduler or by calling the branch first; walk-in passport service is not offered. Bring an unsigned DS-11, original citizenship proof and a photo ID with a copy. If your slot fills up, the Hancock County Chancery Clerk a few blocks away on Highway 90 is a quick alternative in Bay St. Louis.
