Chevy QR Code RPO Decoder: What a Label Scan Tells You
Beginning around the 2018 model year, GM moved Chevrolet factory option codes from the printed glove box label to a QR code on the certification label on the driver-side door pillar. Scanning it with a phone saves you from copying a block of codes by hand, but the result is raw data rather than an explanation: typically the VIN, build details such as the model year and build month, a run of three-character RPO codes, and the paint code, with no descriptions attached. The label covers most factory options but not necessarily every one. To decode the result, look up each code with the vehicle's model and year in mind, or run the 17-character VIN through a lookup that returns the window sticker or the RPO build sheet with descriptions, when those records are available.
Which Chevrolets have a scannable option label
The QR code appears on Chevrolet models from around the 2018 model year, so treat that as an approximate starting point for any one model rather than a hard cutoff. On most models the label is on the driver-side door pillar, and on the Corvette it is on the driver's door. Earlier Chevrolets list their codes in print on the Service Parts Identification label, usually in the glove box. Even on newer vehicles, a scuffed or sun-faded code can fail to scan.
Make sure you're scanning the right code. Dealer stock stickers, auction tags, and windshield decals may carry QR codes too, but those point to listings or inventory systems, not to the factory equipment list. If your Chevrolet has the older printed label instead, our SPID label decoder walks through its layout.
Reading a scan step by step
- Scan with an app that shows the raw text. Many phone cameras try to open whatever they read. A scanner that displays the text first lets you see what the label contains before anything opens.
- Save the result. Copy it into a note or take a screenshot so you can compare it with other records later.
- Find the VIN. Compare the 17-character VIN in the scan character by character with the VIN at the base of the windshield and on the title or registration.
- Pick out the codes. The run of three-character codes is the vehicle's recorded option list. The paint code is listed separately, often as a WA number.
- Translate the codes. Look up individual codes in the RPO code navigator, or run the VIN through the VIN lookup to see the vehicle's factory equipment with descriptions when the record is available.
Why raw codes still need context
A scan gives you codes, and codes only make sense against the right model and year. GU6, for example, indicates a 3.42 rear axle ratio on many GM trucks, and G80 an automatic locking rear differential. But GM has introduced, retired, and reused codes over the decades, so a meaning that holds on one vehicle line may not hold on another.
Not every code describes equipment you can see or use. Option lists also include codes for labels, documentation, market and emissions settings, and sales programs. The navigator lists 4OC, for instance, as "Vehicle Label, Notice to Buyer." Those lines are normal, and they are one reason a raw option list runs longer than the equipment a buyer would recognize. For how these codes map to a specific vehicle's equipment, see Chevrolet RPO Codes by VIN.
Scan, printed label, and VIN record compared
| Source | What you get | Limits |
|---|---|---|
| Label scan | A machine-readable copy of label data that is easy to save, paste, and search | Raw codes without descriptions; may not include every option; a damaged code may not scan |
| Printed SPID label (earlier models) | The option codes in print, plus the paint block at the bottom | No descriptions; can fade, peel, or belong to a replacement glove box door |
| VIN lookup | The original window sticker PDF when available, otherwise the RPO build sheet with code descriptions when that record exists | Some VINs return neither; only the window sticker shows MSRP and option prices |
The option label lists no prices, printed or scanned. Original MSRP and option pricing come from the window sticker, and only when a sticker is available for that VIN.
Using a scan when you inspect a used Chevy
A scan takes seconds during a test drive and gives you something concrete to check afterward. Two comparisons matter most. First, the VIN in the scan against the VIN at the base of the windshield and on the paperwork. On most models the label sits on the door pillar rather than on a removable glove box door, so a mismatch needs an explanation before you go further. Second, the codes against the hardware. If the list includes Z71 or Z82, look for the off-road or trailering equipment that package should bring on that model, and ask about anything missing. A code list describes how the vehicle left the factory, not what has been added, removed, or replaced since.
