QR Code on Certification Label Offers More RPO Codes

Beginning with the 2018 model year, a QR code was added to the Certification label (Fig. 3) on all Buick, Cadillac, Chevrolet and GMC models. The new QR code includes the Vehicle Identification Number (VIN), RPO codes and other information that identify the content of the vehicle. In previous model years, the Service Parts Identification (SPID) label, often located in the trunk or glovebox of a vehicle, included this information.

The two-dimensional QR code is a simple barcode that offers the former SPID information in a digital format. The Certification label on all GM models is located on the driver-side B pillar, with the exception of the Corvette where it’s on the driver’s door.


QR Code Reader

Software to read the QR code is commonly available for any Android, iPhone or Windows smartphone. Many basic applications can be downloaded for free. Tested QR code readers that are easy to use include NeoReader by NM LLC, i-nigma by 3GVision, QR Scanner by Honestly App, QR Droid by DroidLa and Bar-Code by PW2. GM does not recommended any particular software.

TIP: If the vehicle information needs to be retained for service records or shared with others, most scanner software also has a feature to email the data.

For U.S. dealerships, an OPTICON Bluetooth Companion Scanner (2D Imager), tool number PX-20, is available from www.gmdesolutions.com. The scanner works with a USB cable or is connected via Bluetooth to a laptop.


More RPO Codes Added

Once the QR code is scanned, the vehicle information will appear in the following order: VIN, Model Year, Model, Build Month, Year, Engineering Book, Vehicle Order Number, 3 Digit RPO Codes sorted alphanumerically, and the Paint Code (the paint code also appears in the lower left of the QR code). (Fig. 4)

For example, here’s the information as shown from a scanned QR code:

The commas indicate separation of information; however, the RPOs do not have comma separation. Instead, the RPO codes are separated by a space. The RPO codes also are bolded in the example, but not in the actual information displayed from the QR code.

The commas after the paint code indicate the database of the paint code. There are four databases. The example shows the paint code was retrieved from the first database.

Up to 48 RPO codes may be displayed from the scanned QR code. It does not include all the RPO codes as displayed in the Investigate Vehicle History.

RPO descriptions can be found in the appropriate Service Information under General Information. The following table lists the RPO family descriptions that may be included on the vehicle.
