What Every Digit and Character in Your GM VIN Can Reveal

The Vehicle Identification Number (VIN) of your GM holds a wealth of information about your vehicle’s identity, specifications, manufacturing details, and history. Each digit and character in the VIN has a specific meaning, offering valuable insights into your GM’s story. Let’s take a closer look at what each character in your GM’s VIN reveals:

World Manufacturer Identifier (WMI)

The first three characters of the VIN unlock the identity of your vehicle’s origins. The first character reveals the country where it was made, the second pinpoints the manufacturer, and the third provides additional details about the vehicle’s design and features. For GM, the WMI typically starts with “WAU,” signifying the powerhouse behind it—GM AG.

Countries/Regions

Manufacturer/Vehicle Type

Vehicle Descriptor Section (VDS)

Characters four through eight in your GM’s VIN reveal specific details about your vehicle’s identity—covering the model, engine type, series, and other features. These characters are customized to reflect the model and year of your GM vehicle. They often include codes for model line (such as CK for trucks, or CT for SUVs), engine specifications, body style (like sedan, SUV, or coupe), and sometimes special designations or trim features. This section provides a detailed glimpse into the vehicle’s unique configuration.

Check Digit: Still part of VDS, the ninth character is more than just a placeholder—it’s a calculated check digit that ensures the VIN is error-free. Using a unique formula based on the other VIN characters, it acts as a safeguard to detect any mistakes and confirm the VIN’s authenticity.

Vehicle Identifier Section (VIS)

The tenth to seventeenth characters form the Vehicle Identifier Section (VIS), which gives your vehicle its unique identity. It includes codes for the assembly plant, production year, and a specific serial number. The VIS ensures the vehicle can be traced for purposes like recalls, registration, and history reports, making it an important part of its identity.

Model Year: The tenth character represents the model year of your GM. It’s a letter or number that’s more than a random symbol—each one ties your vehicle to a specific year. For example, “J” might point to a 2018 model, while “L” could mean it’s a 2020.

Assembly Plant: The eleventh character is a coded signal of where your GM rolled off the assembly line. This letter or number corresponds to a specific manufacturing plant, giving you a clue about where your vehicle took shape.

Production Sequence Number: The final six digits are the DNA of your vehicle, a unique production sequence number that tracks your GM’s place in the line-up. It sets your ride apart from all others produced at the same plant in the same model year.
