Chevrolet Build Sheet by VIN: RPO Codes and Window Stickers
To pull a Chevrolet build sheet, enter the 17-character VIN in the VIN lookup. For a Chevy, the site first checks for the vehicle's original window sticker, a PDF that shows the factory equipment and the original MSRP. When no sticker is available, it shows the RPO build sheet instead: the three-character Regular Production Option codes recorded for that VIN, each with a short description. Newer Chevrolets are more likely to return a sticker and older ones an RPO list, but neither is promised for any particular vehicle, and some VINs return no record. Both documents describe how the vehicle was equipped when it was built, not how it looks or runs today.
What a Chevrolet RPO build sheet lists
GM tags factory equipment with three-character RPO codes. On the build sheet each code gets its own line next to its description, so a Silverado record might show the engine, transmission, axle ratio, paint color, seat trim and option packages as separate entries. It has no prices, and it often includes entries that never appear on a window sticker.
A typical Chevy RPO list mixes several kinds of entries:
- Powertrain: engine, transmission, rear axle ratio and differential type.
- Packages and trim: off-road, trailering, performance and appearance groups, plus the trim level.
- Color and interior: exterior paint, interior color and seat material.
- Emissions and market: lines tied to the emissions certification or the market the vehicle was built for.
- Production and chassis entries: plant, shipping and routing codes, and parts the factory selected automatically. The site's code navigator, for example, lists JKD as a "Computer-selected suspension component package."
That last group is normal and does not mean a buyer ordered something extra. When a line is unclear, look the code up in the RPO code navigator.
Many Chevrolets also carry a Service Parts Identification label, often in the glovebox, under the console lid or in the trunk, with the same kind of codes printed on it. Those labels fade, get torn out or sit in different places from model to model, which is where a VIN-based record helps.
Window sticker or RPO list: what you will see for a Chevy
Before either document loads, the page shows basic details decoded from the VIN: model year, make, model and, when the decode provides them, trim, body style and engine. A standard VIN decode identifies the manufacturer, model year, assembly plant and certain encoded attributes, such as the engine on many Chevrolets. It cannot tell you whether a Silverado has a locking differential, which axle ratio it uses or what color it was painted. That detail comes from VIN-specific factory records.
The lookup then shows the original window sticker when one is available for that VIN. Only the sticker carries MSRP and option prices, and it groups equipment the way a shopper would read it. When there is no sticker, the page moves on to the RPO build sheet if that record exists. Some VINs return neither; why a window sticker may not be available covers the usual reasons and what to try next.
Chevrolet RPO codes worth recognizing
These codes are widely documented on Chevrolet vehicles. Meanings can shift by model and year, so read the description printed on your own record rather than relying on the table alone.
| Code | Commonly means | Where it usually appears |
|---|---|---|
| Z71 | Off-road package | Silverado, Colorado, Tahoe, Suburban |
| G80 | Automatic locking rear differential | Trucks and SUVs |
| NHT | Max Trailering Package | Silverado |
| Z82 | Trailering package | Trucks and full-size SUVs |
| JL1 | Integrated trailer brake controller | Trucks and some SUVs |
| GU6 / GT4 / GT5 | 3.42 / 3.73 / 4.10 rear axle ratio | Many GM trucks |
| L83 | 5.3L V8 | Full-size trucks and SUVs of certain years |
| L86 | 6.2L V8 | Full-size trucks and SUVs of certain years |
| LS3 | 6.2L V8 | Some Corvette and Camaro SS models of certain years |
| Z51 | Performance package | Corvette |
| 1LE | Track package | Camaro |

What to check on popular Chevrolet models
Silverado, Tahoe and Suburban
Full-size trucks and SUVs are where a build sheet earns its keep. The VIN decode usually tells you the body and engine; the factory record is where you confirm the axle ratio, a G80 locking differential, trailering equipment such as Z82, JL1 or (on Silverado) NHT, and a Z71 off-road package. Two trucks wearing the same badges can be set up very differently. Engine codes for the same displacement changed between generations, so go by the code on your record rather than assuming any 5.3L is an L83.
Corvette and Camaro
On performance cars the package codes carry the weight: Z51 on a Corvette, 1LE on a Camaro. Badges, wheels and aero parts are easy to add after the sale, so a factory code is a much stronger sign of how the car left the plant. When a window sticker is available, it also names the package and shows its price.
Equinox, Traverse, Blazer, Trailblazer and Bolt
For crossovers and EVs the differences are usually trim level, front- or all-wheel drive on models that offer both, driver-assistance and convenience packages, wheels and paint. A window sticker is the easiest document to read here because it names packages in plain language. An RPO list carries the same kind of information as codes, so expect to look a few of them up.
What a Chevrolet build sheet cannot tell you
- Current condition. Mileage, accident history, title status and maintenance are outside the factory record.
- Changes after delivery. Lift kits, gear swaps, replacement wheels and removed equipment won't appear.
- Dealer accessories. Items a dealer installed may be missing from the record or listed differently from factory options.
- Uniform coverage. Records aren't on file for every Chevrolet, and which document you get depends on the individual VIN.
If you are shopping for a used Chevy and want to test a seller's listing against the record, checking options on a used GM vehicle walks through the comparison claim by claim.
