Vehicle license number refers to the digital serial code printed in the 'File Number' column of the motor vehicle license, typically a 12-digit string used for querying traffic violation records. It is usually located on the right side of the third line at the top of the supplementary page of the driving license. Composition of the Vehicle License: The motor vehicle license is the legal document permitting a vehicle to operate on roads within China. The license consists of three parts: the certificate, main page, and supplementary page. The front of the main page contains the endorsed certificate core, while the back displays the vehicle's photo, both sealed in a plastic cover. The supplementary page is also an endorsed certificate core. Contents of the Vehicle License: Includes the license plate number, owner's name, vehicle model and type, engine number and chassis number, load capacity or passenger capacity, initial registration date, and annual inspection records, among others.

As a veteran driver with over 20 years of experience, I believe the vehicle license number is that unique identifier on our driving license, similar to a person's ID card. It's usually located on the front page of the document, consisting of a series of numbers or letters, such as the format 'Jing B12345'. Each vehicle is assigned an exclusive number upon registration by the vehicle management office, serving as proof of the vehicle's identity. I remember when I was young and driving long distances, if stopped by the police for inspection, the first thing they'd ask for was this number. Back then, I didn't understand and hesitated for a long time, which wasted time. Later, I developed a habit of glancing at the driving license before each trip and memorizing a few digits, storing them in my phone as backup. If it's lost or damaged, it's crucial to go to the vehicle management office for a replacement promptly; otherwise, it could cause trouble during vehicle inspections or accident handling. It's safer to keep it in the car usually, and in this digital age, taking a photo to store in the cloud is also an option, but carrying the paper version with you is the most reliable. This number is also linked to insurance claims, so protect your privacy and don't share it casually to avoid fraud.

The vehicle license number is a key identifier in the vehicle management system. It's the code line on the original vehicle license, with each car having a unique combination. For instance, it's as important as the license plate number, used to distinguish different vehicles throughout the entire process from registration to scrapping. I think car owners don't need to memorize too much professional terminology, but they should know where it's used: it speeds up identity verification during traffic department inspections, avoiding being stuck on the road; annual inspection reports and insurance policies may require this number, doubling the efficiency. Once when I went for car repairs, the mechanic asked for the number, input it into the computer, and directly pulled up the maintenance records—so convenient. I recommend taking a photo and saving it in your phone's notes, glancing at it before driving to develop a good habit. Don't overlook the details; if you forget during a random check, you might waste half an hour reapplying. The system is designed for safety and speed, and knowing more doesn't hurt.

The vehicle license number is that string of numbers or letters on the license, like the vehicle's ID. You need to provide it every time you're checked while driving or handling vehicle-related matters—simple and straightforward. I usually take a photo and keep it on my phone for easy access when needed. Don’t take it lightly—if you lose it, it’s a hassle, requiring a trip to the DMV to reapply. Just remember a few key digits—it’s a small thing in daily life but crucial when it counts.
