It is the reservation sequence number, and the number will keep increasing. Relevant information about the driver's license is as follows: 1. Introduction 1: The full name of the driver's license is the motor vehicle driver's license, also known as the "driver's license". According to the law, it is the certificate required for motor vehicle drivers to apply for. Driving a motor vehicle requires certain driving skills.
