What exactly is the frame number?

Vehicle identification code, commonly known as frame number, is a set of character codes assigned by the manufacturer to a vehicle for identification purposes.

The identification code is composed of numbers and capital letters, including 10 digits from 0 to 9 and 23 letters excluding I, O, and Q, which can be easily confused with numbers. The first digit of the identification code represents the country of production; the second digit represents the manufacturer; and the third digit represents the type of vehicle, so combining these three digits can identify the vehicle. The fourth to eighth digits of the identification code represent the features of the vehicle; the ninth digit is the check digit; the tenth digit represents the year of production; the eleventh digit represents the assembly location, where 0 represents the original factory assembly; and the twelfth to seventeenth digits represent the production serial number.

Following ISO's requirements, the original identification code was gradually replaced by the standard Vehicle Identification Number (VIN) code. This code is still a unique identifier for the vehicle and corresponds to the internal system one-to-one. It will not have any impact on the use of the vehicle.
