Downtown Texarkana Post Office

The Downtown Texarkana Post Office occupies a historically significant building on North State Line Avenue — the avenue that literally forms the boundary between Texas and Arkansas. This unique geography means the facility straddles two states, and it functions as a passport acceptance site for residents from both sides of the metropolitan area. Located at 500 North State Line Avenue, Suite 101, the office is steps from Texarkana city center and within walking distance of several local landmarks and government offices.

As a USPS passport acceptance facility, the Downtown location processes new passport applications for adults and minors, accepts requests for passport cards, and can refer applicants seeking renewal-by-mail guidance. The central downtown location makes it a practical choice for Texarkana residents who work or conduct business near the State Line corridor, offering easy access without driving to the Main Post Office on the city's northern edge. Parking is available along adjacent streets and in nearby municipal lots.

Appointments are required and should be scheduled through the USPS online reservation system at tools.usps.com/rcas/. The local phone number for the office is (903) 792-3794 if you need to confirm availability or ask questions before booking.

The Downtown Texarkana Post Office sits at one of the most distinctive postal addresses in the United States — State Line Avenue, where the Texas–Arkansas border runs down the middle of the road. Applicants visiting this office should bring completed DS-11 paperwork, original citizenship evidence, a government-issued photo ID, and a check or money order for the State Department fee.
