The post office handles mail for addresses on Congress Avenue and Guadalupe Street, two of Austin's main downtown corridors. With 212 businesses using this facility, it functions as a commercial mail hub. The setup is typical for major cities where a single post office building offers PO Box service alongside standard carrier delivery routes that cover the surrounding streets.
Just two streets define this facility's service area: Congress Avenue and Guadalupe Street. Both are major downtown Austin corridors lined with businesses, government offices, and mixed-use buildings. The street names don't reveal much about postal logistics since this isn't a traditional geographic ZIP but rather a PO Box designation nested within the urban core.
