Digits 4 to 9 are the VDS. Although each manufacturer has their own way of encoding information in the VDS, some things remain the same. Firstly, this part of the VIN always gives you the vehicle specifications. Secondly, the 8th digit is usually reserved for the engine type. By interpreting the 6 digits of the VDS, you can learn about the automobile platform, model, body type, and more. Digits 10 to 17 are the VIS. The manufacturer uses this part of the VIN to uniquely identify the vehicle. Although the VIS may contain information about the car (such as the transmission choice), it is usually a simple number.
