How to Distinguish Between National V and National VI Vehicles?

[OJulia]

National V and National VI standards are mainly reflected in the different limits for exhaust emissions. To distinguish whether a vehicle is National V or National VI, you can use the following methods: 1. Vehicle Certificate: The vehicle's certificate will clearly indicate which National standard the vehicle belongs to. 2. Vehicle Conformity Certificate: In the exhaust emissions section, there is a CCC certification standard, which is normally a string of numbers. The number after the decimal point represents the National standard to which the vehicle belongs. 3. New Vehicle Acceptance Form: When purchasing a new vehicle, you will receive an acceptance form that includes the model, color, emission standard, engine number, and chassis number. These are usually marked with Roman numerals, where National V is represented by V and National VI by VI.

To distinguish whether a car meets China 5 or China 6 emission standards, I rely on several practical tips after years of driving. First, check the vehicle's conformity certificate or environmental label, usually affixed near the hood or windshield, which clearly states China 5 or China 6. Second, look at the production date—cars made after 2019 in major cities generally meet China 6 standards, while China 5 was common in earlier years. The difference in production time reflects advancements in emission control technology, with China 6 vehicles producing cleaner exhaust and less air pollution. In my neighborhood, China 6 cars enjoy more freedom during traffic restrictions. Third, enter the VIN (Vehicle Identification Number) into the DMV website or app for a quick and free check—don’t just rely on verbal claims, especially during used car transactions. I also recommend asking the dealership for details before buying—China 6 cars are more eco-friendly but may have slightly higher maintenance costs, though it’s worth it for long-term environmental protection. In short, checking official documents is the most reliable way to avoid issues with registration and annual inspections.

I really care about air quality, so checking the emission standard is a must when buying a car. To distinguish between China 5 and China 6, I often use a mobile app to check the VIN. Just enter the chassis number, and the result pops up in minutes—super convenient. The environmental label on the car also states whether it’s China 5 or China 6, usually located on the windshield or door frame. Cars produced in 2019 or later are most likely China 6, while China 5 was the older standard before that. Don’t forget to check the registration column on the vehicle license—it clearly marks the emission level, so don’t skip this step. Under current traffic restrictions, China 6 cars face no limits, while China 5 vehicles are restricted, like being barred from core areas in cities like Beijing, Shanghai, and Guangzhou. I chose China 6 to do my small part for the environment—less tailpipe pollution helps improve urban air. Everyone should pay attention to this when buying a car—it saves money, hassle, and is greener.

Here are a few simple identification methods for regular car owners. Mainly check vehicle documents: The environmental compliance label attached to the car clearly states whether it's China 5 or China 6; Production dates after 2019 are mostly China 6; The VIN can be checked online for emission standards, which is free and quick. China 6 vehicles have newer emission systems with higher exhaust treatment efficiency, causing less health impact, giving you more peace of mind while driving.
