ZIP code 32203 isn't a neighborhood. It's Jacksonville's main mail processing hub, the General Mail Facility on Kings Road. This massive USPS complex handles sorting and distribution for the greater Jacksonville metro area. Only 4 people actually live within its boundaries.
The facility maintains 770 PO Boxes despite having just 1 occupied housing unit. That 770-to-1 ratio tells the story: these boxes serve downtown Jacksonville businesses, government offices, and organizations that want a central mailing address. With 449 business delivery points and 293 employees working at 26 establishments on site, this ZIP functions as a commercial mail hub rather than a residential area.
Building names in the ZIP+4 database read like a USPS organizational chart. You'll find the Plant Manager, Maintenance Engineering, Claims and Inquiry, Stamp Distribution Office, and dozens of other operational units. The Business Mail Entry Unit (BMEU) processes bulk mailings. The Vehicle Maintenance Facility (VMF) keeps delivery trucks running. Express Mail, Registry, and Customer Service operations all have dedicated addresses.
Kings Road is the only street in this ZIP, hosting all 273 street-type delivery records. Secondary units include RM (room) and UNIT designators, pointing to different departments within the complex. The surrounding neighborhoods include New Town, LaVilla, and the Urban Core, all part of Jacksonville's west side.
For anyone sending mail to a 32203 PO Box, you're reaching a business or organization using this facility's centralized box service. Street delivery here goes to USPS operations, not homes.
