What is a Vehicle Identification Number (VIN)?

A Vehicle Identification Number (VIN), is a unique serial number used by the automotive industry to identify individual motor vehicles.

The VIN of your vehicle can be obtained from the registration, title, or actual vehicle. Generally, the VIN is 17 characters made up of numbers and letters. Be sure to use the VIN for the vehicle and not from the trailer.

In 1981, the National Highway Traffic Safety Administration of the United States standardized the format. It required all over-the-road-vehicles sold to contain a 17-character VIN, which does not include the letters I (i), O (o), or Q (q) (to avoid confusion with numerals 1 and 0).

If your VIN is older than 1981, it may have the I (i), O (o), or Q (q) letters and also it may be less than 17-characters. Please replace I (i), O (o), or Q (q) with X and add 'X's at the end of the VIN to make it 17-characters long. For example, if your VIN is A584BIP44E then enter your VIN as A584BXP44EXXXXXXX while e-filing your return.
