ISO 3780:2009 standardizes the WMI, helping to ensure that every motor vehicle has a unique and identifiable marker associated with its manufacturer, which facilitates tracking, registration, and regulatory compliance across global markets.

ISO 3780:2009 is an international standard that defines the World Manufacturer Identifier (WMI) used in the Vehicle Identification Number (VIN). Specifically, this standard establishes the rules and guidelines for the assignment of WMI codes to manufacturers of motor vehicles. The WMI is part of the VIN and helps identify the vehicle's manufacturer or its location of production.
