You can determine a car's model year primarily by decoding its VIN (Vehicle Identification Number), specifically the 10th character. The model year is not always the same as the manufacturing year, as automakers typically release next-year models in the late summer or fall of the preceding year.
The most reliable method is to check the VIN. This 17-character code is unique to each vehicle. The 10th character represents the model year. For example, a car with a 'K' in the 10th position is a 2019 model, 'L' is 2020, 'M' is 2021, and so on. You can use a free online VIN decoder or check the manufacturer's website for a precise breakdown.
Another quick way is to look at the driver's side door jamb sticker. This sticker, which also contains tire pressure information, almost always lists the vehicle's manufacture date. While this is the actual build date, it will tell you the model year; a car built in October 2022 is almost certainly a 2023 model.
The year is also printed on the vehicle's certification label, often found on the door jamb or in the glove compartment. Additionally, you can check the vehicle title and registration documents, which legally state the model year. For older cars, the VIN system was standardized in 1981, so pre-1981 vehicles require different guides.
Here is a quick reference for recent VIN year codes:
| VIN 10th Character | Model Year | VIN 10th Character | Model Year |
|---|---|---|---|
| K | 2019 | R | 2024 |
| L | 2020 | S | 2025 |
| M | 2021 | T | 2026 |
| N | 2022 | V | 2027 |
| P | 2023 | W | 2028 |
If these methods conflict, the documents (title and registration) take precedence. Always cross-reference for accuracy, especially when buying a used car.

Check the VIN—the car's fingerprint. The 10th character is the key. Look it up on a free decoder site. It's the most accurate way. Also, peek at the sticker inside the driver's door; the manufacture date is right there. The paperwork like the title is the final word, but the VIN is your best bet for a quick check before you even go see the car.

I learned this the hard way when I almost bought a car that was a year older than the seller claimed. My go-to move now is to snap a picture of the VIN through the windshield. Then, while I'm still looking at the car, I use my to run a quick decoder search. It takes 30 seconds. I also physically check the door jamb sticker to make sure the dates line up. It saves you from a lot of hassle later.

Start with the physical evidence on the vehicle itself before relying on documents. Locate the VIN on the dashboard. Decode the 10th character. Then, open the driver's door and find the manufacturer's sticker to confirm the production date. These two sources are harder to falsify than a piece of paper. If they match the title and registration, you can be confident you have the correct model year. This systematic approach removes doubt.

As a buyer, you need to verify the year independently. Sellers can make mistakes, intentional or not. The VIN is your most powerful tool. It's standardized and can reveal a lot more than just the year, like the plant where it was built. The door jamb sticker is another great source of truth. If the seller hesitates when you want to check these things, consider it a red flag. Always trust the vehicle's own identifiers over verbal assurances. It’s about protecting your investment.
