Delphi West, the former General Motors parts manufacturing complex in Genesee County, Michigan, operates under dedicated ZIP code 48555. The ZIP+4 records identify AC Rochester West and Fisher Guide CPC facilities on Chevrolet Avenue.

The company went through the longest corporate bankruptcy in American history before being restructured. Core assets were eventually sold to form what is now Aptiv. The designation was added to postal records in October 2008. Flint is the valid mailing city for this designation.
