The most reliable way to determine a car's model year is to check its Vehicle Identification Number (VIN). This 17-character code is the automotive world's fingerprint, and the 10th character almost always specifies the model year. For cars built after 1980, you can use a free online VIN decoder or check the driver's side dashboard or doorjamb sticker to find this information.
While the VIN is definitive, there are other clues. The model year is often listed on the vehicle title and registration documents. Physically, you can check the driver's side doorjamb sticker for the manufacturer's date, but note this is the production date, which may precede the model year. Sometimes, the model year is also embedded in the serial number on the engine block.
It's a common misconception that a car's model year corresponds to the calendar year it was sold. Manufacturers typically release new models in the second half of the previous year. For example, a 2025 model might go on sale as early as mid-2024. Relying solely on visual cues like headlight or taillight design can be misleading due to mid-cycle refreshes.
The table below shows how the 10th VIN character corresponds to the model year for a sample of years.
| VIN 10th Character | Model Year | VIN 10th Character | Model Year |
|---|---|---|---|
| G | 2016 | L | 2020 |
| H | 2017 | M | 2021 |
| J | 2018 | N | 2022 |
| K | 2019 | P | 2023 |
If the VIN is unavailable, your next best step is to contact a dealership's parts department with the license plate number; they can often pull the model year from their system.

















Pop the door open and look at the sticker on the frame. That's the first place I check. It'll have the month and year the car was made. Just remember, if it was built in, say, October 2023, it's probably a 2024 model. The surefire way is to grab the VIN from the bottom of the windshield and plug it into a free decoder online. It spits out the model year instantly.

As someone who's bought and sold a few cars, I always do a three-point check.

The single most important piece of information is the VIN. Everything else is just a clue. The 10th character is the key. For instance, a 'K' means 2019, an 'L' is 2020, and so on. I recommend using the NHTSA's official VIN decoder tool because it pulls directly from the manufacturer. It's free, authoritative, and gives you the definitive answer in seconds, along with other important specs like the plant where the car was assembled.

You really need to look at both the hard data and the car itself. Start with the VIN decoder online for the official model year. Then, look at the car's styling and features. If the VIN says it's a 2022, but it has the exact taillights from the 2021 model, that might indicate a late production date or a minor spec. This two-step process helps you understand the car's full history and confirms that all the information is consistent, which is crucial for valuing it correctly.
