What is the frame number?

Frame No.: Vehicle Identification Number, referred to as VIN, is a set of seventeen English numbers used in a unique set of numbers on a car to identify the manufacturer, engine, chassis serial number and other performance of the car. In order to avoid confusion with the 1,0, the English letters "I", "O", "Q" will not be used.

Common location of the frame number

In addition to the frame number, the frame number can be seen on the lower left side of the front windshield, on the engine, on the nameplate at the lower end of the B-pillar at the co-pilot opening, and on the chassis of the vehicle.

The purpose is to check the numbers, verify that the VIN is filled correctly, and prevent counterfeit products. It is the remainder of the other 16-bit word multiplied by the sum of its position weights divided by 11, when the remainder is 0-9, the remainder is the test number; when the remainder is 10, the letter "X" is used as Check the numbers.
