What does the electronic driver's license core number mean?

[DiEmily]

Electronic driver's license core number is the barcode on the driver's license, and each driver's license has a different core number. Its main purpose is to prevent the continued use of the original driver's license after reissuance. Introduction to driver's license core number: There is a 13-digit number on the back of the driver's license (original), which is the core number of the driver's license. The first 2 digits represent the province, the 3rd digit is the check digit, and the last 10 digits are the serial number. Each driver's license core number is unique. Driver's license precautions: If the driver's license is lost, you can obtain a new license by applying for a replacement at the vehicle management department. The core number on the old driver's license will be invalidated simultaneously, and the newly issued driver's license will have a new core number. If the police find a suspicious driver's license during management, they can also accurately determine whether the driver's license is valid by identifying the core number.
