Explanation of Regular Production Option (RPO) Codes

Typical RPO Label:

DESCRIPTION
The Regular Production Option (RPO) label is placed on the vehicle to aid service and parts personnel in identifying parts and options originally installed on the vehicle. A typical RPO label is shown in the accompanying image.

Knowledge of the RPO identification system can help identifying and ordering parts. Systems and assemblies may be uniquely identified by refering to the label.

GM assigns a three digit/letter code to parts, assemblies, and systems. These RPO codes designate "options" and are assigned by General Motors. Some system testing and part suppliers require RPO information to accurately match systems, parts and assemblies.
