How to Check Which National Emission Standard Your Vehicle Meets
4 Answers
Methods and steps to check your vehicle's emission standard: 1. The simplest and most direct way is to look at the vehicle's environmental protection label, which has clear markings on the back. Just examine it carefully to find the information. 2. You can visit professional query websites for reliable results. 3. For new vehicles, you can check the vehicle's factory certificate, where the information can be found. However, the original certificate is usually kept at the vehicle management office, so it's recommended to make a copy when purchasing a new car for future reference. 4. You can also personally visit the environmental protection window at the vehicle management office with your vehicle's registration certificate, where the staff will assist you in checking the information.
I recently helped my neighbor look this up, and there are actually several ways to check the emission standard (China IV, V, etc.). The easiest is to check the environmental label on your car's windshield—that small sticker will have a prominent "China V" or "China VI" printed in the top-right corner. Alternatively, you can check the vehicle license. Flip to the third item on the auxiliary page under the 'Brand and Model' section. The alphanumeric code there will include a 'V' for China V or 'VI' for China VI. For example, my neighbor's car had 'SVW71811LM,' which indicates a China V vehicle. The most reliable method is to visit the official 'Motor Vehicle Environmental Protection' website, enter the VIN and engine number, and get instant results. This official system has clear records for vehicles dating back to 2008.
You youngsters can handle it right on your phones! Open Alipay and search for 'Vehicle Environmental Protection Inquiry', then enter the license plate number and the last six digits of the engine number – the results pop up in three seconds. My Changan CS75 showed 'China VI B' when I checked last year. But note that this query requires the phone number registered with the vehicle. If checking a company-owned car, you'll need to register it as a non-personal vehicle via the Traffic Management 12123 app first. Also, there's an 'Emission Standard' section directly labeled on the second page of the vehicle registration certificate. This green booklet usually gets buried after buying a car, so you'll need to dig it out.
An experienced mechanic shares a practical tip: First, check the back of the fuel tank cap! Many car models have a small label inside the fuel filler neck, indicating GB18352.5-2013 for China V or GB18352.6-2016 for China VI. Then, open the engine hood and look for the nameplate—the emission standard line, though small, is definitely there. For Volkswagen owners, you can also check the eighth digit from the end of the engine number: 'L' means China VI, and 'K' means China V. My old Jetta’s engine number starts with 'J,' corresponding to the China IV standard. If all else fails, drive to an inspection station—their equipment can connect to the OBD port and scan for immediate results.
