Actually, I usually look at used vans more often. Here are a few simple tips. The most direct way is to find the Vehicle Identification Number (VIN) at the bottom left of the windshield. The 10th digit of that 17-digit code indicates the year, for example, 9 stands for 2009, and M represents 2021. You can also check the sticker inside the driver's door or the nameplate, which shows the manufacturing date. However, the biggest concern when a used car is encountering one with a rolled-back odometer. In this case, you should cross-verify with the vehicle registration certificate and compulsory insurance records—the first registration date on the documents can't be faked. If there's an original owner's maintenance manual, even better, as it usually records the initial registration date. It's recommended to cross-check these details, which is much more reliable than relying solely on the nameplate.

Last week, I helped my best friend inspect a car and saw this. The easiest way is to open the passenger door—there’s a yellow and black nameplate on the door frame, clearly stating the assembly month like "2020/06". The registration date on the duplicate of the vehicle license is also reliable, but if you’re a used car, this date might be a month or so later than the actual production date. If you can’t find the nameplate, check the duplicate of the compulsory traffic insurance policy—the vehicle registration date recorded by the insurance company is usually accurate. By the way, some domestic cars even stamp the production year on the engine block, though the location is so tricky you might need a flashlight to find it.

If you want to modify a car, you need to verify its actual age. Simply jot down the VIN, search for a VIN decoding website on your , and enter it—the vehicle's birthdate will pop up on the third screen. Some apps can scan the QR code on the vehicle registration certificate to pull up records, clearly displaying the registration date and the date filed with the DMV. For early imported cars, checking the date on the environmental sticker under the windshield can also work. Remember the VIN's 10th digit pattern: 2001-2009 corresponds to 1-9, 2010-2030 cycles from A onward, and for 2025, it's P.

Anyone in the auto trading business knows that checking a car's age requires a three-pronged approach. First, look at the VIN sticker in the lower left corner of the windshield—snap a photo and compare it with the initial registration date shown on the DMV website. If the discrepancy exceeds three months, be cautious. Next, pop the hood and remove the panel beneath the passenger-side wiper to find the assembly nameplate embedded there. The most reliable method is checking records—but watch out for cars with multiple ownership transfers, as new policy dates may be inaccurate. Nowadays, some brand dealership systems can even trace the factory pre-production schedule via the VIN, though this requires connections to pull off.

For your own car, there's really no need to check. Just open the first page of the motor vehicle registration certificate, and the string of numbers under "Registration Date" is the legally recognized birthday. But what if you're someone else's car and don't have this certificate? Here's a trick: check the production batch number on the seatbelt label—the last four digits usually represent the year and week number. The tire date code can also work, but it might not be accurate if the tires have been replaced. Honestly, the easiest way is to go to the local vehicle management office and apply for a vehicle file inquiry. For twenty yuan, you can print a vehicle information sheet with all the key dates stamped in red.
