Motor vehicle QR codes are located on the lower left side of the front windshield or in the vehicle's manual. Below is relevant information about motor vehicle QR codes: Functions of the vehicle QR code: It can convert and store vehicle-related information in the QR code; The QR code automatically records the vehicle's annual inspection documents; Traffic police can use QR code scanning technology to record vehicle violation penalty information; Check vehicle inspection marks via the vehicle QR code; Use the vehicle QR code to establish a vehicle monitoring network to ensure effective, real-time, and automated vehicle management. Introduction to motor vehicle QR codes: Motor vehicle QR codes contain license identification information such as the issuing authority, unique serial number, and license plate number. They also include the vehicle's technical parameters and owner information. Only traffic police internal devices can scan these QR codes—ordinary mobile phones cannot recognize them, so there is no need to worry about personal information leakage or other issues.
I've been driving for many years, and the most common location for QR codes is the lower right or left corner of the front windshield, usually firmly affixed in the corner on the driver's side. This thing is actually part of the environmental label or insurance sticker, which gets scanned by inspectors during annual vehicle inspections to check emission data. If the QR code is worn or smudged, the inspection can easily run into issues, so I always avoid that area when washing my car. Some newer cars also have a QR code on a metal plate in the engine compartment, linked to the Vehicle Identification Number (VIN), making it easier for repair shops to quickly look up parts. Overall, as someone who frequently handles the steering wheel, keeping the QR code clear saves a lot of hassle—otherwise, you might have to make an extra trip to the DMV to get it reissued. It's a good habit to glance at it before driving to ensure it's clean and intact.
From the perspective of automotive digitization, QR codes are now ubiquitous, primarily located in designated areas on the inner side of the windshield, such as near the environmental compliance sticker. Scanning them instantly retrieves vehicle inspection records and insurance information, and can even be done via WeChat. Some premium vehicles feature QR codes on door frames or engine covers for service appointments or battery status checks. Through experimentation, I found that blurry QR codes can cause scanning failures, affecting online annual inspection applications. The trend is moving toward electric vehicle QR codes being linked to battery safety certifications, potentially relocating near the center console. Remember to regularly check and avoid damaging these labels, as small details in the digital era bring significant convenience.
