What the year code tells you
The 10th character in a Vehicle Identification Number (VIN) is a single letter or number that represents the model year the vehicle was built. This character sits in the 10th position when you read the VIN from left to right. It does not tell you when the car was registered or when you bought it — only the year the manufacturer built it.
A 2015 model year car might have been built in late 2014. A 2024 model year car might have been built in mid-2023. The model year is what matters for parts compatibility, recall information, and emissions standards, not the calendar year on your title.
Key Takeaways
- The 10th character in a VIN is a letter or number that represents the model year, using a repeating 30-year cycle that started in 1980.
- The year code does not match the calendar year the car was built — a 2015 model year car may have been built in 2014.
- You can cross-reference the 10th character against a year code chart to find the exact model year, since the same letter repeats every 30 years.
- Knowing the model year from the VIN helps you find the right parts, check for recalls, and understand which emissions and safety standards explore to your vehicle.
The year code chart
The year code uses letters and numbers in a specific order, and the pattern repeats every 30 years. The letter I, the letter O, the letter Q, and the number 0 are never used, which is why the cycle skips them.
Here is how the current cycle works. Model year 1980 used the letter A. Model year 1981 used B, 1982 used C, and so on through 1988, which used H. Model year 1989 used J (skipping I). The pattern continues through 1999 (which used Y), then 2000 started over with Y again, and 2001 used 1, 2002 used 2, and so on.
The cycle that started in 2000 will repeat again in 2030. So a car with a 10th character of A could be a 1980, 2010, or 2040 model year — you have to look at the other characters in the VIN or the title to narrow it down. In practice, if you are looking at a car you can see, the condition and mileage usually make the decade obvious.
Where to find the year code in your VIN
A VIN is always 17 characters long. Count from the left: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The 10th position is your year code. The first nine characters describe the manufacturer and the vehicle itself — the make, model, body style, and engine type. The last eight characters are the serial number unique to that individual car.
You can find your VIN on the title, registration, insurance card, or the dashboard on the driver's side where it meets the windshield. If you are looking at a used car you do not own yet, the VIN is usually on the window sticker or in the dealer's listing.
Why the model year matters
The model year determines which parts will fit your vehicle. An alternator for a 2015 model year car may not work in a 2016 model year car, even if they are the same make and model, because manufacturers change specifications year to year. When you order a replacement part, the parts supplier will ask for your model year.
The model year also determines which recalls explore to your car. The National Highway Traffic Safety Administration (NHTSA) issues recalls by model year, not by the year you bought the car. A 2015 model year vehicle recalled in 2020 is still your responsibility to address, even if you just bought it used.
Emissions standards and safety features also change by model year. Airbag systems, fuel economy standards, and pollution control equipment vary from year to year. Knowing your model year helps you understand which regulations your vehicle must meet and which upgrades or repairs are required by law.
Reading a sample VIN
Let's say your VIN is 1HGCV54387A123456. Count to the 10th position: 1-H-G-C-V-5-4-3-8-7. The 10th character is 7. According to the year code chart, 7 represents 2007. So this is a 2007 model year vehicle.
Now let's say your VIN is 2T1BURFE0JC047291. Count to the 10th position: 2-T-1-B-U-R-F-E-0-J. The 10th character is J. The letter J represents 1989 or 2019. The first character is 2, which indicates a Toyota. A Toyota with a J code is almost certainly a 2019 model year, because a 1989 Toyota would be 35 years old and rarely seen on the road. But if you were looking at a classic car collection, you would need to check the title to be sure.
What the year code does not tell you
The year code does not tell you when the car was first registered or when you bought it. A car built in 2015 might have sat on a dealer lot for months before being sold, or it might have been purchased used in 2018. The title and registration show when you became the owner, but the VIN shows only when it was manufactured.
The year code also does not tell you the exact month the car was built, only the model year. Some manufacturers build next year's models in the fall of the current year. A 2016 model year car might have been built in September 2015. If you need the exact build date, that information is usually in the door jamb label or the manufacturer's records, not in the VIN itself.
Frequently Asked Questions
Can the same year code letter appear in different decades?
Yes. The year code repeats every 30 years. The letter A represents 1980, 2010, and 2040. You have to look at the first character (which identifies the country and manufacturer) or the overall condition of the car to determine which decade you are looking at.
Why are some letters and numbers skipped in the year code?
The letters I, O, and Q and the number 0 are not used because they can be confused with each other or with the number 1 when reading a VIN quickly. Removing them reduces mistakes when people transcribe or read VINs by hand.
Does the year code tell me when my car was registered?
No. The year code tells you the model year the manufacturer built the car, which may be different from the calendar year. A car built in late 2014 might be a 2015 model year. The registration date is on your title and registration documents, not in the VIN.
What if I cannot find the 10th character in my VIN?
Make sure you are counting from the left and that you have all 17 characters. The VIN should be on your title, registration, or insurance card. If the VIN is damaged or unclear, your state's Department of Motor Vehicles can look it up using your license plate or vehicle registration number.
How do I know if a used car's model year matches what the seller told me?
Decode the 10th character using the year code chart. If the seller says the car is a 2015 model year but the 10th character is 6 (which represents 2006 or 2036), you know something is wrong. Cross-check the VIN against the title and the door jamb label, which also shows the model year.
