A World Manufacturer Identifier (WMI) is a unique code consisting of the first three characters in a Vehicle Identification Number (VIN), which identifies the vehicle’s manufacturer, as well as its country of origin and vehicle type. The WMI for a 2001 GMC Sierra, for example, can begin with “1GT” or “2GT”, signifying that it is a truck manufactured by General Motors LLC in Warren, Michigan, United States. The specific WMI not only distinguishes the vehicle as being made by General Motors but also indicates it’s a model produced for certain years, including 2001. This code is crucial for vehicle registration, identification, and recall purposes. The variation in the first digit reflects the geographical location of the manufacturer, with “1GT” identifying a vehicle made in the United States and “2GT” traditionally used for vehicles also manufactured by General Motors but possibly intended for different regions or having different specifications.
