What does a Silverado window sticker prove?
The Silverado is sold in more trims, cabs, beds and engines than almost any other truck. Two trucks with the same badge can differ by thousands of dollars in options. The original window sticker lists the trim, cab and bed, the engine and transmission, each package and option with its price, the destination charge and the total MSRP. It also shows EPA fuel economy for the 1500 and the plant that built it.
On a used truck, that answers what a buyer needs to know. Is it a real Trail Boss? Does it have the locking rear axle and the trailering package? Which V8 is under the hood?
How do I read Silverado trims and packages by generation?
T1 (2019 model year on). GM began mainline production of the 2019 Silverado at Fort Wayne, Indiana in 2018, and Silao, Mexico followed. The previous generation was built alongside it for a time, so a 2019 can be either truck.
Recent 1500 trims run WT, Custom, Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, High Country and ZR2. Engines have included the 2.7L turbo four, sold as TurboMax on later trucks, the 5.3L V8, the 6.2L V8 and the 3.0L Duramax diesel. The trim decides which engines you can get, so the sticker is the record for each truck.
GM builds every truck from three-character RPO codes. The sticker names options in words. Codes you’ll see on Silverado paperwork include:
| RPO code | What it is |
|---|---|
| Z71 | Off-road package |
| G80 | Automatic locking rear differential |
| NHT | Max Trailering Package |
| L87 | 6.2L V8 |
The 6.2L V8 and the Max Trailering Package add towing ability and value. The sticker shows both as priced lines, so you can confirm them before you pay for them.
How do I tell a Trail Boss from a Z71 on a used Silverado?
This is the most common mix-up on Silverado listings. Z71 is an off-road package offered on several trims. A Z71 badge alone doesn’t tell you the trim.
- LT Trail Boss and Custom Trail Boss are trims. They include the Z71 Off-Road Package and add a factory 2-inch suspension lift.
- LT with Z71 is an LT with the off-road package. It has no factory lift.
- RST is a street-styled trim, not a Trail Boss.
- ZR2 is the top off-road trim, a step above Trail Boss.
An LT with an aftermarket leveling kit and Trail Boss badges looks close to the real thing. The sticker’s trim line can’t be faked. Check the engine line too. Trail Boss trucks have been offered with more than one engine, and the bigger V8 cost more new.
Also check for G80 and the towing package. Many sellers say “max tow” when the truck only has the standard trailering package.
Where are the VIN and paint code on a Silverado?
The VIN is on the dash at the base of the windshield on the driver’s side. It is also on the certification label on the driver’s door pillar.
The paint code and the RPO list are on the Service Parts Identification label in the glove box on older trucks. From the 2018 model year, GM added a QR code to the driver’s-side certification label that carries the same data, with the paint code printed beside it. Our GM paint code page explains the WA and U prefixes.
How do I get a Silverado window sticker by VIN?
Enter the truck’s 17-character VIN. The NHTSA decode, the trim, the recall count for that model and year, and the check for an original sticker are all free. You see whether a sticker is on file before you pay. Open recalls on that VIN are listed at nhtsa.gov/recalls.
With a sticker on file, the $9.99 Full Report adds the sticker PDF, every option with its price, the paint code where it can be matched, and recall details. If no sticker is on file, we tell you first.
Without a sticker, read the RPO list from the SPID label or QR code, and compare it with the current lineup on chevrolet.com. The Chevy window sticker page covers the rest of the Chevrolet range. To see what the truck cost new, option by option, read original MSRP and options by VIN.
