GMC Paint Codes

On Sierra trucks, the service parts identification sticker is usually inside the glove box. On the Yukon, Terrain, and Acadia, it's on the driver's door jamb. The sticker is packed with RPO codes. Look for the row labeled "U" to find your paint code.

If the sticker has been removed or is unreadable, any GMC dealer can pull the code from the RPO database using your VIN.

GMC is a General Motors brand, so it uses the same WA paint code system as Chevrolet, Cadillac, and Buick. On the service parts identification sticker you'll see a code next to "U" (upper body) and sometimes "L" (lower body for two-tone). Codes are 3 to 6 characters like GAN (Summit White), G1W (White Frost Tricoat), or GBA (Onyx Black).

The Sierra 1500 is the most common GMC model with two-tone paint. If your truck has a different color on the lower body or bumpers, you'll see both U and L codes on the sticker. Make sure you write down both.
