📖 About this office
The Biloxi Main Post Office sits at the heart of downtown Biloxi's Old Town district, steps from the Back Bay waterfront. As a designated USPS passport acceptance facility, it processes DS-11 first-time applications and lost/stolen passport replacements for residents throughout the Mississippi Gulf Coast. The building serves both retail postal customers and applicants who arrive by appointment to submit their passport paperwork to a trained acceptance agent.
Applicants traveling from areas like D'Iberville, Ocean Springs, or Long Beach will find this centrally located office convenient, sitting within a short drive of US-90. Passport photos are available on-site, sparing applicants a separate errand before their appointment. The office accepts payment by check or money order for the government fee portion; the acceptance fee is paid separately.
Because USPS acceptance is strictly by appointment, residents should schedule online at tools.usps.com well in advance — slots fill quickly in the spring and summer travel season. Completed applications are forwarded to a regional processing facility, with routine service taking 6–8 weeks and expedited service available for an additional fee.
