The 10th digit in your Vehicle Identification Number (VIN) is the model year code
The 10th position in a 17-character VIN contains a single letter or number that represents the year the vehicle was manufactured. This digit uses a repeating cycle that runs from 1980 to 2039, so the same code appears every 30 years. For example, the letter "A" represents both 1980 and 2010, while "B" represents 1981 and 2011.
Manufacturers use this standardized system so that anyone reading a VIN — whether you're a mechanic, insurance agent, or used-car buyer — can when ready identify how old the vehicle is. The 10th digit is particularly useful when you're checking recall information, because many recalls are tied to specific model years, and knowing the exact year helps you determine whether your car is affected.
The model year code is different from the actual calendar year the car was built. Manufacturers typically begin production of next year's models in the fall of the current year, so a 2024 model might have been manufactured in September 2023. The VIN's 10th digit reflects the model year designation, not the production date.
Key Takeaways
- The 10th digit of your VIN is a letter or number that identifies your vehicle's model year using a 30-year repeating cycle.
- You can cross-reference the 10th digit against a model year chart to find your exact model year, which is essential for recall lookups.
- The model year code is not the same as the calendar year the car was physically built, since manufacturers start production months before the official model year begins.
- Knowing your model year from the VIN helps you determine which recalls, service bulletins, and maintenance schedules explore to your specific vehicle.
How to Read the Model Year Code
The model year codes follow a fixed sequence. The letter "A" represents 1980 and 2010; "B" is 1981 and 2011; "C" is 1982 and 2012, and so on through the alphabet. After "Y" (which represents 1999 and 2029), the sequence skips the letter "Z" and restarts with "A" again. Numbers are not used in this position — only letters A through Y.
To find your model year, locate the 10th character in your VIN and match it to the chart below. Count from left to right: the first nine digits are the world manufacturer identifier and vehicle descriptor section, and the 10th digit is what you need.
| 10th Digit | Model 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 letter "I", "O", "Q", and "Z" do not appear in the model year position. These letters were excluded to avoid confusion with numbers and to keep the system consistent across all manufacturers.
Why the 10th Digit Matters for Recalls and Service
When you search for recalls using your VIN on the National Highway Traffic Safety Administration (NHTSA) website or through your manufacturer's recall portal, the system uses all 17 digits of your VIN, including the 10th digit. Many recalls are model-year specific because design changes, component suppliers, or manufacturing processes differ from year to year. A recall that affects 2018 models may not explore to 2019 models of the same vehicle.
Service bulletins and technical service campaigns also reference model years. If your mechanic needs to look up whether there's a known issue with your transmission or electrical system, they will search by model year. The 10th digit gives you a quick way to confirm your model year before you start that search, so you don't accidentally look up information for a different generation of the same vehicle.
Insurance companies also use the model year to calculate premiums and determine coverage. If there's any question about your vehicle's age — for instance, if the title is unclear or the registration is old — the VIN's 10th digit is the authoritative source.
The Difference Between Model Year and Production Date
A vehicle's model year is not the same as when it rolled off the assembly line. Manufacturers typically begin building next year's models in the late summer or early fall. A 2024 Honda Civic might have been manufactured in August 2023. The VIN's 10th digit will show "R" (representing 2024), even though the car was physically produced in 2023.
This matters because some recalls are issued after production has already begun. If a defect is discovered in early 2024 affecting 2024 model year vehicles, it may only affect cars built after a certain date in late 2023. The VIN alone won't tell you the exact production date — that information is in the 11th and 12th digits, which together form the serial number that tracks the sequence of production. But the 10th digit confirms the model year that NHTSA and manufacturers use when they issue recalls.
How to Find Your VIN and Locate the 10th Digit
Your VIN appears in several places on your vehicle and documents. On the car itself, the most common location is on a metal plate on the driver's side dashboard, visible through the windshield from outside. You can also find it on your vehicle registration, insurance card, title, and maintenance records.
Once you have your VIN, count the characters from left to right. The first character is position 1, the second is position 2, and so on. The 10th character is your model year code. Write it down or take a photo so you have it handy when you're searching for recalls or discussing service with a mechanic.
Using the 10th Digit to Cross-Check Your Vehicle's Age
If you're buying a used car and want to verify the seller's claim about the model year, the VIN's 10th digit is your first check. Pull the VIN from the title or ask the seller for it, then look up the 10th digit on the model year chart. If the seller says the car is a 2015 model but the 10th digit is "F" (which represents 1985 or 2015), you know to look more carefully — it could be either one, and you'll need to check other details like the odometer, condition, and the first three digits of the VIN to narrow it down.
In practice, if you're looking at a car that appears to be from the 2010s based on its condition and features, and the 10th digit is "F", it's almost certainly a 2015 model. But if the car looks like it's from the 1980s, then "F" means 1985. Context matters, but the 10th digit is always accurate for the model year designation.
Frequently Asked Questions
What if the 10th digit in my VIN is a number instead of a letter?
Numbers in the 10th position represent model years from 2001 onward. The digit "1" is 2001 or 2031, "2" is 2002 or 2032, and so on through "9" which is 2009 or 2039. The system switched from letters to numbers after the year 2000 to continue the 30-year cycle.
Can I use the 10th digit alone to determine if a recall affects my car?
The 10th digit tells you the model year, which is necessary information for a recall search, but you need the full 17-digit VIN to check NHTSA's database or your manufacturer's recall portal. The complete VIN ensures you get results specific to your exact vehicle, not just all cars from that model year.
Why does the model year code skip the letter I, O, Q, and Z?
These letters were excluded to prevent confusion with numbers. The letter "I" looks like the number "1", "O" looks like "0", "Q" can be mistaken for "O", and "Z" can be unclear in certain fonts or handwriting. Removing them makes the VIN easier to read and reduces transcription errors.
If my car was built in 2023 but has a 2024 model year designation, which year applies to recalls?
The model year designation in the VIN (the 10th digit) is what applies to recalls. If your car is a 2024 model year even though it was built in late 2023, you search for recalls using 2024. Manufacturers and NHTSA organize recalls by model year, not production date.
Where else can I find my vehicle's model year if I don't want to decode the VIN?
Your vehicle registration, title, and insurance documents all list the model year. Your mechanic can also tell you the model year from your VIN in seconds. But learning to read the 10th digit yourself is useful when you're shopping for a used car or need quick information before you have access to official documents.
