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.
