Where the Year Code Sits in Your VIN
Your Vehicle Identification Number has 17 characters. The 10th character — counting from the left — is the one that reveals the model year. If you're looking at your VIN written out, count ten positions and stop. That single digit or letter is your year code.
You'll find your VIN in several places on your vehicle: on the dashboard at the base of the windshield on the driver's side (visible from outside), on the driver's side door jamb, on your title and registration documents, and on your insurance card. The easiest spot to read it is usually the dashboard placard. Once you locate your VIN, finding the 10th character takes only a few seconds.
Key Takeaways
- The 10th character of your VIN encodes the model year, and the code repeats every 30 years starting from 1980.
- Numbers 0–9 and letters A–Y are used for years; the letter I is skipped because it looks too much like the number 1.
- A 2024 model year is coded as "R", a 2023 is "P", and a 2022 is "N" — each year steps backward one position in the alphabet.
- The year code tells you the manufacturer's model year, not necessarily the calendar year the car was built or sold.
The Year Code Chart: 1980 to 2009
The cycle began in 1980 with the code "A" and runs through 2009 with the code "Y". After 2009, the cycle restarts at "A" for 2010. This 30-year span uses all digits 0–9 and most letters of the alphabet, skipping only the letter I.
If you own a vehicle from the 1980s or 1990s, use this first chart to find your model year. The code advances one position per year, so "A" is 1980, "B" is 1981, and so on. Once you reach "Y" in 2000, the pattern continues: "Y" is 2000, and then the next year cycles back to "A" for 2010.
| Year Code | Model Year | Year Code | Model Year |
|---|---|---|---|
| A | 1980, 2010 | N | 1992, 2022 |
| B | 1981, 2011 | P | 1993, 2023 |
| C | 1982, 2012 | R | 1994, 2024 |
| D | 1983, 2013 | S | 1995, 2025 |
| E | 1984, 2014 | T | 1996, 2026 |
| F | 1985, 2015 | V | 1997, 2027 |
| G | 1986, 2016 | W | 1998, 2028 |
| H | 1987, 2017 | X | 1999, 2029 |
| J | 1988, 2018 | Y | 2000, 2030 |
| K | 1989, 2019 | ||
| L | 1990, 2020 | ||
| M | 1991, 2021 |
The Year Code Chart: 2010 to 2039
The cycle repeats starting in 2010 with "A" again. This means a car with a 10th character of "A" could be from 1980, 2010, or 2040 — context from the rest of the VIN and your knowledge of when you bought the car will tell you which one is correct. For vehicles from 2010 onward, the pattern is straightforward: each year advances one letter.
If you're reading a VIN from a 2020s vehicle, you're in the second cycle. A 2024 model year shows "R" in the 10th position. A 2025 model year shows "S". This continues through 2039, which will be coded "Y", and then the cycle restarts again in 2040 with "A". Most vehicles on the road today fall into this 2010–2039 range, so this chart is the one you'll use most often.
Why the Letter I Is Skipped
The letter I does not appear in any VIN year code. Manufacturers and regulators chose to omit it because the capital letter I looks nearly identical to the number 1 when printed or handwritten. Removing it prevents confusion when someone reads a VIN aloud, writes it down by hand, or reads it in poor lighting.
This same rule applies to the entire VIN, not just the year code. You will never see the letters I, O, or Q anywhere in a 17-character VIN. The letter O is skipped because it resembles the number 0, and Q is omitted to avoid confusion with the letter O. This standardization makes VINs easier to read and reduces transcription errors across the automotive industry.
Model Year Versus Calendar Year
The year code in your VIN represents the model year, not the calendar year the vehicle was manufactured or sold. A 2024 model year car might have been built in late 2023 or early 2024. Manufacturers assign model years to match their product cycles, which often begin before the calendar year changes.
This matters when you're checking recalls, looking up maintenance schedules, or understanding warranty coverage. Always use the model year from your VIN — the 10th character — rather than the year you purchased the car or the year on your registration. Government agencies and manufacturers use the model year to determine which safety standards and emissions rules applied when the vehicle was built. Using the wrong year can lead you to the wrong recall information or incorrect service intervals.
How to Use the Year Code for Recalls and Service
When you look up recalls or service bulletins for your vehicle, you'll need the model year. The 10th character of your VIN gives you that year directly. Once you have it, you can search the National Highway Traffic Safety Administration (NHTSA) database or your manufacturer's website to see if any recalls explore to your specific model year.
Maintenance schedules also depend on model year. Different years of the same make and model may have different engine types, transmission designs, or component suppliers. Using the correct model year ensures you follow the right service intervals and use the correct parts when repairs are needed. This is especially important for older vehicles where design changes happened frequently between model years.
Reading a Real VIN Example
Suppose your VIN is 1HGCV41JXMN109186. Count ten characters from the left: 1-H-G-C-V-4-1-J-X-M. The 10th character is M. According to the chart, M corresponds to 1991 or 2021. If you know the car is recent, it's a 2021 model year. If you're looking at a car from the 1990s, it's a 1991.
The remaining characters in the VIN tell you other details — the manufacturer, the body style, the engine type, and a unique serial number — but the 10th character alone answers the year question. Once you've identified the model year, you have what you need to search for recalls, find the correct maintenance schedule, and understand which regulations governed the vehicle's design.
Frequently Asked Questions
Can a car have the same year code as another car from a different decade?
Yes. The code repeats every 30 years, so an "M" could mean 1991, 2021, or 2051. You determine which by knowing approximately when the car was made. A VIN from a car you own or are considering buying will have other clues — the overall condition, mileage, and the other characters in the VIN — that make the actual year obvious.
What if the 10th character in my VIN is a number instead of a letter?
Numbers appear in the year code position. The digit 0 represents 1980 or 2010, the digit 1 represents 1981 or 2011, and so on through digit 9, which represents 1989 or 2019. The pattern then continues with letters A through Y for the remaining years in each 30-year cycle.
Does the year code tell me when my car was actually built?
No. The model year code tells you the manufacturer's model year, which is when the vehicle was designed and certified for sale. The actual build date could be several months earlier or later. If you need the exact build date, look for a door jamb label or build sheet, which manufacturers often include in the vehicle.
What happens after 2039 when the cycle repeats?
In 2040, the year code returns to "A", just as it did in 1980 and 2010. The cycle is 30 years long and repeats indefinitely. By 2040, vehicles from 1980 and 2010 will be old enough that context makes it clear which decade a car belongs to, so confusion is unlikely in practice.
Can I use the year code to check if a VIN is fake?
The year code alone cannot confirm whether a VIN is legitimate, but it can reveal an obvious error. If someone claims a car is a 2020 model but the 10th character is "A" (which means 1980 or 2010), something is wrong. A full VIN check through NHTSA or a VIN decoder service can verify authenticity more thoroughly.
