Jonesboro, AR

ZIP code 72403 is a post-office-box ZIP for Jonesboro, Arkansas, so it does not define a residential neighborhood or a land area with landmarks strictly inside it. Prominent sites in the broader Jonesboro area include Arkansas State University, Centennial Bank Stadium, First National Bank Arena, Craighead Forest Park, and the downtown district. These landmarks serve the community rather than a distinct 72403 boundary.
