Motor vehicle QR codes are located at the lower left corner of the front windshield or in the vehicle's instruction manual. The vehicle QR code contains license identification information such as the issuing authority, unique serial number, license plate number, as well as the vehicle's technical parameters and owner information. Only specialized systems used internally by traffic police can scan these QR codes. The functions of motor vehicle QR codes include: 1. Converting and storing vehicle-related information in the QR code; 2. Automatically recording the vehicle's annual inspection documents in the QR code; 3. Allowing traffic police to record vehicle violation and penalty information by scanning the QR code; 4. Enabling the query of vehicle inspection marks via the QR code; 5. Facilitating the establishment of a vehicle monitoring network to ensure effective, real-time, and automated vehicle management.

As a seasoned driver, I'm well aware of the location of the vehicle QR code—it typically refers to the identification QR code of the vehicle, serving as a simplified version of the VIN, conveniently placed on the lower left or right corner of the windshield for easy scanning, visible both from inside and outside the car. For instance, when I first bought my car, the dealer reminded me to check this sticker to ensure it wasn't obscured by rain or dust. Registration documents like the vehicle license or insurance card often come with a QR code, which can be scanned to quickly retrieve vehicle information for annual inspections or accident handling. If you can't find it, there might also be labels under the hood or on the door frame. Developing a habit of checking it regularly can save you trouble, as driving safety is paramount. If the sticker is damaged, it's advisable to visit the DMV or an authorized dealership for a replacement—efficient and hassle-free.

Having worked at a car dealership for years, I often see car owners puzzled about the QR code location: it's essentially a convenient version of the vehicle identification number, primarily affixed to the driver's side corner of the windshield—position varies by model, sometimes tilted toward the upper right. Registration books or insurance documents usually print it as backup. A quick phone scan during inspection reveals the vehicle's history—super handy. If weather causes smudging, wipe it promptly or request a replacement sticker; don't wait for trouble to act. Car maintenance tools often remind us to regularly verify such details—this habit has saved me plenty of roadside headaches.

I've been using cars for decades in my daily life. The vehicle QR code is actually affixed under the windshield, usually at the left corner. It's also printed on the registration certificate. If you can't find it, it's common for it to be wiped off during car washes or to become faded with age. Simply go to the vehicle management office to apply for a reprint. Scanning this code for quick vehicle information checks is extremely practical.
