What is the process of changing the phone number of the violation notice?

You can go to the vehicle management office or the traffic police brigade vehicle management office group with your driving license, or log in to the online vehicle management office and enter relevant vehicle information as required.

When registering a new car, you need to fill in the mobile phone number, which is opened by default and does not need to be handled separately. If the mobile phone number is changed, you can apply to the local vehicle management office for change. There is a "contact information change" when you log in to the "business application" in the "Vehicle Management Office of the Traffic Management Bureau of the Public Security Bureau" in each city. Fill in the license plate number, engine code, resident ID card, etc. You can go in, see the previous contact number and modify it.
