Where are RPO Codes Located?

Beginning with the 2018 model year, a QR code was added to the Certification label on all Buick, Cadillac, Chevrolet and GMC models. The new QR code includes the Vehicle Identification Number (VIN), RPO codes and other information that identify the content of the vehicle. In previous model years, the Service Parts Identification (SPID) label, often located in the trunk or glovebox of a vehicle, included this information. Example of RPO codes label
