After successful number selection, the number plate number will be kept for 15 working days from the next day, during which it is not allowed to select the number again or modify the submitted information. After the transfer, you can bring your valid ID card to the vehicle management office window to cancel the transfer.
2. If you don't register after the deadline, you will automatically give up. After the owner chooses the license plate number successfully, the system will default to 15 working days, giving the owner the time to go through the registration formalities. During this period, the owner can't register, and the system will consider the owner to give up automatically after the expiration. Moreover, during this period, car owners are not allowed to participate in the new license plate shake number and modify the shake number registration information.
