What Is a GMT800 RPO Sticker?

The RPO (Regular Production Option) sticker — also called the Service Parts Identification (SPID) label — is a white sticker found inside the glove box of every GMT800-platform truck and SUV. It lists every factory-installed option as a series of 3-character alphanumeric codes covering the engine, transmission, axle ratio, exterior paint, interior trim, option packages, and much more.

This decoder translates all of those codes instantly, organized by category, so you know exactly how your vehicle left the factory. Whether you're buying, selling, restoring, or just curious, decoding your RPO sticker gives you the definitive factory build sheet.
