RPO Code Navigator
Browse 4,139 GM RPO codes from the site's reference list by first character. It is a reference selection, not every code GM has used. To see the codes recorded for one vehicle, look up its VIN: Chevrolet, Buick, Cadillac and GMC vehicles without an original window sticker on file may return an RPO build sheet, when that record is available.
A code's meaning can differ by model, year and GM division. Chrysler, Jeep, Dodge, Ram, Fiat and Alfa Romeo vehicles use factory sales codes, which are not listed here; for those brands the lookup returns the factory build sheet, when available.
