Characters 1-3 of a GMC VIN
World Manufacturer Identifiers (WMIs) are unique codes composed of three letters or numbers that identify the manufacturer of a vehicle. These codes can reveal several details about a vehicle, such as the manufacturing company, vehicle type, and even the geographical location of its manufacturing facility. For example, General Motors LLC utilizes numerous WMIs for its various vehicle types, including trucks and multipurpose passenger vehicles (MPVs), across a range of model years extending from 1981 to 2024. The WMIs beginning with 1G, 2G, 3G, and 2CT specifically designate vehicles made by General Motors in Warren, Michigan, United States, covering a variety of model years and vehicle types. This system of identification allows for easy recognition and classification of vehicles worldwide.
