What is the purpose of the Vehicle Identification Number?

The uses of the Vehicle Identification Number are: 1. Identifying vehicle information, the Vehicle Identification Number is also known as the car's ID card; 2. Safety recalls and assisting law enforcement with vehicle identification; 3. Preventing car owners from being deceived. The Vehicle Identification Number consists of 17 characters and is also referred to as the 17-digit code or the car's ID card. The Vehicle Identification Number can be used to query the production country, manufacturing company, and manufacturer of the vehicle, as well as the vehicle type, brand name, model series, body style, engine model, vehicle model, safety protection device model, inspection digits, assembly plant name, and production sequence number, which are of significant importance.

The Vehicle Identification Number (VIN) is like a car's ID card, staying with it from purchase to scrapping. When I went to transfer ownership, it was used to check the vehicle records. The DMV verifies the engine number and chassis number entirely based on the VIN. During repairs, mechanics scan this code to find original part models—last time I replaced a sensor, it was this string of numbers that matched the correct part. When filing an insurance claim, the company also requires photos of the VIN; otherwise, it delays the damage assessment. Now, when buying a used car, checking the VIN is even more critical. If the code under the windshield appears scratched, it's likely a refurbished accident vehicle. Once, when my car was scratched in a parking lot, the traffic police used the other car's VIN to track down the owner's information.

Our auto repair shop deals with VINs every day. You can find this 17-digit code on the firewall nameplate when you open the hood. During maintenance, scanning the VIN with a diagnostic tool directly pulls up the service manual, automatically displaying details like the recommended oil volume for the model year. Last time we encountered a car with modified performance, we relied on the VIN to retrieve the original ECU program for reflashing. Nowadays, parts suppliers require the last six digits of the VIN for orders—otherwise, we might receive the wrong transmission filter and have to arrange returns. Once, when a customer broke down on the highway, I remotely identified a common fuel pump issue through the VIN before the tow truck arrived, allowing the repair shop to prepare the replacement part in advance.

When picking a used car, I scrutinized the VIN more carefully than the odometer. By entering the VIN on the traffic management bureau's website, you can check for flood damage records—that's how I avoided a flooded car I nearly bought last time. For imported cars, pay extra attention to the 10th digit of the VIN: 'L' indicates a 2020 model, while 'M' means 2021, helping you avoid dealers selling old stock as new. During ownership transfer, the DMV's VIN scanner works ten times faster than manual checks—last year, I helped a friend complete the car inspection in just three minutes. Nowadays, even rental companies require VIN photos at return to prevent disputes over swapped parts.
