World Manufacturer Identifiers (WMIs) are unique codes assigned to every vehicle manufacturer, pinpointing vital information about the vehicle, including its manufacturer, type, and origin.

These WMIs are critical for identifying the vehicle’s manufacturing location in Warren, Michigan, United States, and distinguishing the Suburban as a versatile MPV. Additionally, the 3GT WMI is designated for General Motors trucks produced in the same location, illustrating the diverse range of vehicles classified under General Motors’ WMIs. Understanding a vehicle’s WMI is essential for vehicle registration, identification, and tracking its manufacturing history.
