If you're having trouble decoding vehicles in your inventory, consider this list of errors and challenges commonly faced when working with Vehicle Identification Numbers.
- Your VIN contains illegal characters. VINs can use any alphanumeric character, except for the letters I,O, and Q.
- Your VIN isn't 17 digits long. Starting with model year 1981, all VINs are required to be 17 digits long.
- Your VIN does not pass the VIN checksum test. See our article on VIN Validation for more information about the VIN checksum.
