Everything you need to know about the GM VIN

What is a GM VIN?

The GM Vehicle Identification Number (VIN) is a 17-character code, unique to every GM car or motorcycle in the world. This sequence of letters and numbers contains information about the vehicle’s specifications, which is essential when you want to confirm the details in a used car ad. Additionally, it’s also great for learning about a vehicle’s history - government agencies use the GM VIN to log important data, which will help you avoid buying a stolen or damaged machine.


What does the GM VIN contain?

GM VIN’s consist of three distinct parts:

  • Digits 1-3 are the World Manufacturer Index (WMI). This tells you where a vehicle was made, who the manufacturer is, and what type of vehicle it is.
  • Digits 4-9 are the Vehicle Description Section (VDS). The meat of any GM VIN - this tells you the vehicle’s characteristics, such as the engine and transmission type.
  • Digits 10-17 are the Vehicle Identification Section (VIS). A unique serial number.

Where to find it?

There are several places, where you will typically find your GM VIN:

  • Search for a metal plate on the driver’s side of the dashboard (look from outside the vehicle)
  • Try the driver’s side door frame - usually around where the door latches to the car
  • Expensive car parts will sometimes carry the VIN (try the engine block)
  • Car documents, such as the car title or insurance certificate
