The license plate number of a used car cannot be transferred directly, but it can continue to be used under certain conditions.
According to the "Motor Vehicle Registration Regulations", when the ownership of a vehicle changes, the license plate number of the original owner can continue to be used by the new owner. Specifically, when the vehicle is transferred to someone else, the original owner can choose to retain the original license plate number, provided that the vehicle license plate needs to be used for more than one year and all violations of the original vehicle are dealt with. The new owner also has the right to apply for the use of the license plate, but needs to re-select the number and license it after completing the transfer of the used car.
In addition, if the original owner wants to keep the license plate number after the transfer, he must purchase a new car within six months and reuse the license plate number. When registering a newly purchased motor vehicle, the new owner can apply to the vehicle management office to use the original motor vehicle license plate number, but it needs to meet certain conditions, such as the original motor vehicle owner has owned the original motor vehicle and used the original license plate number for more than one year, and the road traffic safety violations and traffic accidents involving the original motor vehicle have been dealt with.
