How to Read a GM Window Sticker

A GM window sticker follows a consistent layout across Chevrolet, GMC, Cadillac, and Buick. Once you know what each section means, you can quickly find the information you're looking for — whether that's the original price, the exact option packages, or the fuel economy rating.

Vehicle and VIN header

The top of the sticker identifies the vehicle: make, model, trim level, exterior color, interior color, and the 17-character VIN. The VIN is the unique identifier that ties the sticker to one specific vehicle off the assembly line. Everything else on the sticker describes exactly how that VIN was built.

Standard equipment

This section lists everything that comes on the vehicle as part of its base configuration for that trim level. These items have no individual price listed because they're included in the base MSRP. Typical entries include engine, transmission, wheel size, standard safety systems (like automatic emergency braking or lane-keep assist), infotainment screen size, and interior material.

Optional equipment and RPO codes

This is the most detail-rich section. Each line shows:

• An RPO code — a three-character alphanumeric code like Z71, NHT, or C7E — that corresponds to a specific option or package.
• The plain-language description of that option.
• The individual MSRP price for that option or package.

RPO codes are GM's internal shorthand for every configuration choice. The Z71 Off-Road Package on a Silverado or Colorado, for example, is a single RPO code that bundles suspension components, skid plates, and all-terrain tires. Packages like these can affect resale value significantly, so knowing whether they're factory-installed (vs. dealer-added or aftermarket) matters.

For a deeper look at how RPO codes compare to what you see on the window sticker, see Window Sticker vs. Build Sheet.

Pricing breakdown

The price section is structured as a running total:

• Base MSRP: The starting price for the vehicle at its trim level before any options.
• Options: Each optional item listed individually with its price.
• Destination and delivery charge: A fixed freight charge from the assembly plant to the dealer. This is a standard line item on all new GM vehicles.
• Total MSRP: The sum of base price, options, and destination charge.

These figures represent the manufacturer's suggested price — actual transaction prices vary based on dealer negotiation, incentives, and market conditions.

EPA fuel economy

Near the bottom of the sticker you'll find the EPA-rated fuel economy: city, highway, and combined figures. For hybrid and electric vehicles, the figures are in MPGe (miles per gallon equivalent) or miles of range. The sticker also includes an EPA-estimated annual fuel cost based on standard assumptions about fuel price and annual mileage.

Pull up your own sticker

The easiest way to see all of this for your specific vehicle is to look up your VIN. Enter the 17-character VIN and the tool returns the GM window sticker if it's on file. For older vehicles, it falls back to the build sheet showing all RPO codes directly.
