WMI/VIN Information

Since 1981, global automotive manufacturers have utilized a complex numbering system called a Vehicle Identification Number (VIN) that uniquely describes a vehicle. This number provides a coded description of the vehicle including: manufacturer, year of production, place of production and vehicle characteristics. Because of our unique position within the mobility industry, SAE International is contracted by the National Highway Traffic Safety Administration (NHTSA), to assign a selected portion of the VIN, specifically called the World Manufacturers Identifier (WMI).

If you produce complete, on-road vehicles in the United States, NHTSA regulations require you to place the complete VIN on your vehicles. To begin the process, please contact:

WMI Application

For Non-US Based Manufacturers:
Beginning January 1, 2012, SAE will begin charging a one-time only fee of $525 USD for companies needing a World Manufacturers Identifier (WMI) code from areas outside of the United States where there is no governing body established to assign a WMI Code.

The code provided will be for on-road vehicles only.

Non-US WMI Application

WMI Verification Letters
Beginning in November 2009, SAE instituted a $50 fee for all verification letters requested. These letters are used to verify a company's WMI code as well as their manufacturer's information. To request a verification letter, please contact Kris Siddall at
