The VIN tells you the model year in the 10th position
The 10th character in a vehicle identification number (VIN) is a single letter or number that represents the model year. This position is standardized across all manufacturers, so once you know where to look, you can decode it on any car, truck, or motorcycle.
A VIN is always 17 characters long. Count from the left: the 10th position sits between the 9th character (which identifies the manufacturer's plant and body style) and the 11th character (which begins the serial number unique to that individual vehicle). This year code repeats on a 30-year cycle, so a car built in 1980 and one built in 2010 both carry the same year code — but the rest of the VIN and the vehicle's condition will tell them apart.
Key Takeaways
- The 10th character in any VIN is the model year code, using letters A through Y and the number 0 (the letter I, O, Q, and Z are never used).
- The year code repeats every 30 years, so you need the full VIN and context to distinguish a 1980 model from a 2010 model.
- You can find the VIN on the driver's side dashboard (visible through the windshield), the driver's door jamb, or your vehicle registration and insurance documents.
- Online VIN decoders are free and will show you the year along with other details like engine type and transmission, though they cannot verify ownership or title status.
Where to locate your VIN
The easiest place to find a VIN is on the dashboard of the driver's side, visible from outside the vehicle through the windshield. Look at the lower left corner where the dashboard meets the glass — the VIN is printed on a metal or plastic plate and reads left to right.
If the dashboard VIN is worn or unreadable, check the driver's side door jamb (the vertical edge where the door closes). Open the door fully and look at the frame — the VIN is usually stamped or printed there. You can also find it on your vehicle registration, insurance card, and title documents. If you are buying a used vehicle and the seller provides paperwork, the VIN appears on the bill of sale and any inspection reports.
The year code chart
The 10th character uses this pattern, repeating every 30 years:
| Character | Years |
|---|---|
| A | 1980, 2010 |
| B | 1981, 2011 |
| C | 1982, 2012 |
| D | 1983, 2013 |
| E | 1984, 2014 |
| F | 1985, 2015 |
| G | 1986, 2016 |
| H | 1987, 2017 |
| J | 1988, 2018 |
| K | 1989, 2019 |
| L | 1990, 2020 |
| M | 1991, 2021 |
| N | 1992, 2022 |
| P | 1993, 2023 |
| R | 1994, 2024 |
| S | 1995, 2025 |
| T | 1996, 2026 |
| V | 1997, 2027 |
| W | 1998, 2028 |
| X | 1999, 2029 |
| Y | 2000, 2030 |
| 1 | 2001, 2031 |
| 2 | 2002, 2032 |
| 3 | 2003, 2033 |
| 4 | 2004, 2034 |
| 5 | 2005, 2035 |
| 6 | 2006, 2036 |
| 7 | 2007, 2037 |
| 8 | 2008, 2038 |
| 9 | 2009, 2039 |
Notice that the letters I, O, Q, and Z do not appear in the year code. Manufacturers skip these to avoid confusion with the numbers 1 and 0. If you see one of these letters in the 10th position, you are looking at a different part of the VIN or the VIN is not formatted correctly.
How to read a sample VIN
Here is a real-world example. Take the VIN: 1HGCV41JXMN109186. Count to the 10th character from the left: 1-H-G-C-V-4-1-J-X-M. The 10th character is M, which corresponds to 1991 or 2021. To know which one, look at the first character: 1 means this vehicle was built in the United States. A 1991 model would be 33 years old; a 2021 model would be 3 years old. The condition of the vehicle, mileage, and any service records will confirm which decade is correct.
The first three characters (1-H-G) identify the manufacturer — in this case, Honda built in Japan. The next five characters (C-V-4-1-J) describe the body style, engine, and transmission. The 10th character (M) is the year. The 11th character (N) identifies the assembly plant. The final six characters (109186) are the serial number unique to this specific vehicle.
Using a free online VIN decoder
If you do not want to count manually, you can paste the full VIN into a free online decoder. These tools when ready show you the year, make, model, engine type, transmission, and other factory specifications. They work by matching the VIN against manufacturer databases and do not require any personal information from you.
A decoder is useful when you are buying a used vehicle and want to verify that the year listed on the title matches what the VIN says. It can also show you whether the vehicle came with a standard or optional engine, which affects resale value and repair costs. However, a decoder cannot tell you whether the title is clean, whether there are liens against the vehicle, or whether it has been in an accident — you need a title search and vehicle history report for that.
Why the 30-year cycle matters when buying used
The year code repeats every 30 years because manufacturers assumed no vehicle would still be in regular use after three decades. When you are looking at a vehicle from the 1980s or 1990s, the 10th character alone is not enough — you must also check the title, registration, and odometer reading. A 1980 Honda with 45,000 miles is extremely rare; a 2010 Honda with 45,000 miles is normal.
If you are buying a vehicle and the seller claims it is a 2010 model but the title says 1980, or vice versa, that is a red flag. The title is the legal record, and it should match both the VIN and the year code. If there is a discrepancy, do not proceed with the purchase until a dealer or mechanic has inspected the vehicle and confirmed the actual year.
Frequently Asked Questions
Can I find the year if part of the VIN is missing or damaged?
If the 10th character is illegible, you cannot decode the year from the VIN alone. Check your registration, insurance card, or title — they all list the model year separately. If those documents are also missing, a dealer or mechanic can inspect the vehicle and estimate the year based on design, components, and manufacturing details, though this is less reliable than the VIN.
What if the 10th character is a letter I, O, Q, or Z?
These letters are never used in the year code position. If you see one of them in the 10th spot, you may have miscounted the characters or the VIN is not authentic. Recount carefully from the left, or verify the VIN against your title or registration.
Does the VIN year match the calendar year the car was built?
Not always. The model year is assigned by the manufacturer and typically begins production several months before the calendar year ends. A 2024 model may have been built in late 2023. The VIN year code reflects the model year, not the exact month of manufacture.
Can I use the VIN year to check if a vehicle is still under warranty?
The model year is one factor in warranty coverage, but it is not the only one. Warranties are based on the purchase date, mileage, and the specific coverage plan. Use the VIN year as a starting point, then contact the manufacturer or dealer with the full VIN and purchase date to determine warranty status.
