How is the motor vehicle contact number invalid?

If the current mobile phone number is inconsistent with the registration in the traffic control department, it is recommended to change the registration information as soon as possible to ensure timely receipt of SMS violation tips.

According to article 17 of decree-law 17. 124 issued by the Ministry of Public Security and Article 20 (2) of the Work Specification for Motor Vehicle Driver's License issued by the Traffic Management Bureau of the Ministry of Public Security: If (stop number, change number) leads to inconsistency with the reserved number, I need to bring a valid ID card, driving license or driver's license to the local vehicle management office to change the mobile phone number left in the vehicle or driver's file.

Generally, you only need to fill in a change information form, and you will be notified by SMS after the vehicle management office has reviewed it (5 working days).
