ZIP 78505 isn't a neighborhood or town. It's a dedicated PO Box facility in downtown McAllen, Texas. The post office sits on S 12th Street in the heart of Hidalgo County's largest city, surrounded by McAllen's Historic Business Redevelopment district. While McAllen proper has a population over 140,000, this ZIP has zero residents because it exists solely to provide postal services.
The facility maintains 495 PO Boxes serving 190 businesses and their 688 employees. That's roughly one box for every four workers in the immediate area. Downtown businesses, professionals, and organizations use these boxes for reliable, centralized mail access. The post office also accepts mail addressed to S 12th Street with unit numbers, a feature called PO Box Street Addressing that gives boxes a street-style address.
McAllen sits just seven miles from the Mexican border at Reynosa, Tamaulipas. The city serves as a major commercial gateway, and this downtown postal facility handles mail for cross-border businesses, legal offices, and trade-related enterprises. The 78505 ZIP is enclosed within the larger 78501 ZIP, which handles street delivery for the surrounding area.
Three historical aliases appear in postal records: McColl, Kane, and Bonner. These names aren't valid for mailing today, but they trace back to small communities that existed before McAllen absorbed them. The names survive as echoes of the Rio Grande Valley's development from scattered settlements into today's metro area of over 900,000 people.
The only street is S 12th Street, the post office's physical address used for PO Box Street Addressing.
ZIP Code 78505 supports both business and residential activity. According to the Business Census (2024), there are 25 business establishments, employing about 627 people with an annual payroll of $35,445,000.
