What is a VIN?

VIN stands for “vehicle identification number,” and it is the unique code assigned by manufacturers for a specific motor vehicle. Also known as a serial number, a VIN is the automotive equivalent of a social security number; no two vehicles in operation have the same VIN.

Decoding the Characters of a VIN:

Since 1981, the National Highway Traffic Safety Administration (NHTSA) standardized how VINs in the United States were assigned. Under the NHTSA standard, a VIN is composed of 17 characters (consisting of numbers and letters) with each set of numbers having a specific meaning. A VIN will never include the letters I, O, and Q to avoid being mistaken for 1 and 0.

Where Can I Locate a Car’s VIN?

The VIN is most commonly located on the dashboard on the driver's side of the vehicle. It can be viewed by standing outside the car and looking on the corner of the dashboard where it meets the windshield. If the VIN cannot be found there, it can be found by opening the driver's side door and looking on the door jamb. Here is an example VIN from a 2015 Toyota Highlander SUV: 


Why is it Important to Look Up VIN Numbers?

If you’re considering buying a used car, it’s important to check the vehicle’s VIN to determine if a used car is suspect or not.
