How to check the violation by SMS, and what code to send? I am a mobile phone user in Lanzhou, Gansu.

The easiest way to find out whether there are illegal deductions and fines for vehicles is to go online to the online business hall of the vehicle management office in the city where you are looking for household registration, and enter the car number, vehicle model and the last six digits of the vehicle identification code or frame number (some inquiry systems can find out only by entering the last four digits of the identification code). The vehicle identification number and frame number are on the vehicle driving license. I hope it helps you. I wish you happiness! Drive safely! Please adopt!
