ZIP Code 95799 in West Sacramento, California, is a specialized USPS internal ZIP assigned to the Sacramento Processing & Distribution Center on Industrial Boulevard. This isn't a residential delivery area. It's an administrative designation used exclusively for routing mail to departments and offices within the postal facility itself.
The ZIP+4 database contains 50 records, all at a single address. What appear as "buildings" are actually internal departments: District Manager, Headquarters Finance, Labor Relations, Consumer Affairs, and dozens of other administrative units. USPS uses department names and room numbers (like "RM 5000" and "DEPT" designators) to route internal mail within the facility.
There's no population, no PO Boxes, and no residential delivery within 95799. The facility itself sits within ZIP 95691, which handles actual mail delivery for this location. West Sacramento residents and businesses use standard ZIPs like 95691, 95605, or 95691 for their mail.
This classification as a PO Box ZIP ("P" classification) is a legacy database designation. It doesn't mean West Sacramento residents use PO Boxes. It means 95799 was set up as an internal routing code, not a public delivery ZIP. The city delivery indicator shows "Y" because West Sacramento has extensive street delivery through its standard ZIP codes.
