Window Sticker vs. Build Sheet: What's the Difference?

Both a window sticker and a build sheet describe how a specific GM vehicle was assembled at the factory — but they serve different purposes, contain different information, and have different availability as vehicles age. Knowing which one you need (and when you can get it) saves time.

What is a window sticker?

The window sticker — also called the Monroney label — is the consumer-facing factory document required by federal law on every new vehicle sold in the U.S. It's written in plain English, includes pricing, fuel economy ratings, warranty terms, and a description of standard and optional equipment. It's designed to be read by a car buyer standing on a dealer lot. For a full breakdown of what it contains, see What Is a Window Sticker?

What is a build sheet?

A build sheet is the production record that travels with the vehicle through the assembly plant. For GM vehicles, the build sheet is essentially a list of RPO (Regular Production Option) codes — short alphanumeric codes like L87 or JL1 — that together describe every factory choice for that VIN: engine, transmission, color, packages, option upgrades, and more. It's not a consumer document; it's a manufacturing document. There's no pricing, no fuel economy, and no plain-language formatting — just codes and descriptions.

How they compare

• Audience: The window sticker is for buyers; the build sheet is for technicians, enthusiasts, and researchers who know how to read RPO codes.
• Pricing: The window sticker shows full MSRP and per-option prices. The build sheet has no pricing at all.
• Format: The window sticker is formatted like a retail document with labeled sections. The build sheet is a code list.
• Options detail: Both list factory options, but the build sheet is often more complete — it includes production codes that don't appear on the sticker.
• Availability by age: Window stickers are reliably available for GM vehicles from roughly 2020 and newer (most reliably 2022+). Build sheets, because they originate from older dealer service records, sometimes survive for older vehicles when the sticker does not.

Which does windowstickervin.com show?

This tool tries the window sticker first. If it's on file for your VIN, you get the full consumer-facing document — with pricing, equipment descriptions, and fuel economy. If no window sticker is available (common for pre-2020 vehicles), the tool automatically falls back to the build sheet — so you still get a complete list of factory RPO codes and their descriptions, even when the sticker itself is gone.

To see which is on file for your vehicle, look up your VIN. For more on when stickers go missing, see Why Is My Window Sticker Not Available?
