ZIP code 98490 serves a commercial facility on S 56th Street in South Tacoma, Washington. This ZIP was introduced in October 2006 to handle mail for a single building or business complex. It doesn't serve a residential community or traditional neighborhood.
The post office maintains 96 PO Boxes and provides direct delivery to 45 business locations, all within a single multi-tenant building on S 56th Street. With 71 ZIP+4 records showing UNIT designators, this is a Large Volume Receiver classification. The building houses multiple businesses that share a common address but receive mail through individual unit numbers.
Despite its PO Box classification in the postal database, 98490 actually has city carrier delivery service. The classification is a technical designation from when the ZIP was created. It's located within the boundaries of standard ZIP code 98409, which serves the surrounding South Tacoma area. Residents and businesses nearby receive their mail through neighboring standard ZIPs, not through 98490.
This type of facility-specific ZIP is unusual for a PO Box classification. Most PO Box ZIPs serve entire communities or regions, but 98490 exists solely to streamline mail sorting for a single high-volume commercial location. The presence of both PO Boxes and unit-based delivery reflects the building's need to handle large volumes of business mail efficiently.
