GM RPO option codes

General Motors marks factory equipment with three-character RPO codes (Regular Production Option) for Buick, Cadillac, Chevrolet, GMC and Pontiac vehicles. Enter a code to see what it means.

Enter a code or a comma-separated list of codes, e.g. ZL9 or LF5,FE2,KF3.

Descriptions come from manufacturer data and are shown in their original language: mostly English, some in German.

Check the car behind the codes

Codes tell you how a car left the factory. The Automoli vehicle history report shows what happened to it next: mileage, damage and legal status.
