Where else can I verify the 27H code?

What is a GM build sheet?

A build sheet is General Motors' own factory assembly record for a specific VIN. It lists the RPO (Regular Production Option) codes the vehicle was built with — every package, individual option, paint and trim selection, axle ratio, and equipment group — exactly as it left the plant.

Where a window sticker is written for the buyer with plain descriptions and pricing, the build sheet is the underlying code-level truth. It's the most reliable way to confirm how a used Chevrolet, Buick, Cadillac, or GMC was originally configured, long after the original paperwork is gone.

Window sticker vs. build sheet

Newer GM vehicles (roughly 2020 and later) usually have the original window sticker PDF on file — the Monroney label with standard and optional equipment, fuel economy, warranty, and the full MSRP breakdown.

When a window sticker isn't on file, this tool automatically falls back to the build sheet: the list of RPO codes with their descriptions. Either way you come away with the factory record of how the vehicle was equipped.

RPO codes explained

Every factory option on a GM vehicle has a three-character RPO code — for example a specific paint, a tow package, a sunroof, or an audio system. These codes are also printed on the label inside the glovebox or spare-tire well.

The build sheet pairs each code with a readable description, so you can translate a glovebox full of codes into the actual packages and features the vehicle carries. That makes it easy to verify a seller's claims or settle exactly which options are factory.

27H — Cloth interior trim: Light Cashmere/Ebony. This code identifies the factory upholstery material, color combination, or interior trim specification. Browse RPO codes →

I am trying to document the original configuration of a 2023 Chevrolet Colorado. Code 27H is shown as “Cloth interior trim: Light Cashmere/Ebony. This code identifies the factory upholstery material, color combination, or interior trim specification” Which source is usually most reliable when the build sheet, window sticker, and dealer printout do not use identical wording?

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Cloth interior trim: Light Cashmere/Ebony. This code identifies the factory upholstery material, color combination, or interior trim specification” is a reasonable plain-English reading, but the exact implementation should be verified for the 2023 model.
