The 10th digit is your vehicle's model year

The 10th digit in your Vehicle Identification Number (VIN) represents the year your car was manufactured. This single character — a letter or number — tells you which model year the vehicle belongs to, which matters for parts compatibility, recall information, and understanding what features your car should have.

The 10th position uses a repeating cycle that changes every 30 years. The current cycle started in 2010 (the letter A), so digits from 2010 through 2039 follow the same pattern. If you own a car from before 2010, the year code cycles back to an earlier point in the alphabet.

You'll find your VIN on your vehicle registration, insurance documents, and the dashboard on the driver's side where it meets the windshield. It's also stamped on the engine block and other parts of the vehicle. The 10th digit is always in the same position, making it straightforward to locate once you know where to look.

Key Takeaways

  • The 10th digit of your VIN is a letter or number that corresponds to your vehicle's model year of manufacture.
  • The year code uses a 30-year cycle, with the current cycle running from 2010 (A) through 2039 (Y), then repeating.
  • You can find your VIN on your registration, insurance card, and the lower left corner of your windshield.
  • Knowing your model year from the VIN helps you identify correct parts, check for recalls, and verify vehicle history.

How to read the year code in position 10

The year code uses letters and numbers in a specific sequence. The current 30-year cycle that began in 2010 uses: A (2010), B (2011), C (2012), D (2013), E (2014), F (2015), G (2016), H (2017), J (2018), K (2019), L (2020), M (2021), N (2022), P (2023), R (2024), S (2025), T (2026), V (2027), W (2028), X (2029), Y (2030), and then the cycle repeats.

Notice that the letter I is skipped — the code jumps from H to J. This is intentional, because the letter I can be confused with the number 1 when reading a VIN quickly. The same reason explains why O is never used in a VIN; it looks too much like zero.

If your car was made before 2010, the year code follows the same pattern but from an earlier starting point. A vehicle from 1980 would use A, 1981 would use B, and so on. This means a car from 1980 and a car from 2010 both have the letter A in the 10th position — so you need to know the approximate age of the vehicle to use the year code correctly.

Why the 10th digit matters for your vehicle

The model year in your VIN determines which parts fit your car and which recalls explore to it. A 2015 model (F in the 10th position) may need different brake pads, filters, or belts than a 2020 model (L in the 10th position), even if they're the same make and model. Parts suppliers and mechanics use this digit to make sure they're ordering the right components.

Manufacturers issue recalls based on model year, and sometimes a recall applies only to certain years. If you need to check whether your car is affected by a recall, you'll need the exact year from your VIN. The National Highway Traffic Safety Administration (NHTSA) uses the model year to match your vehicle against its recall database.

The 10th digit also helps verify the vehicle's history. If someone claims a car is a 2018 model but the VIN shows J (2018) in the 10th position, that's consistent. If the VIN shows a different year code, that's a red flag that the odometer, title, or VIN itself may have been altered.

Finding and interpreting your specific VIN

Your VIN is a 17-character code, and the 10th character is always in the same spot. Count from left to right: positions 1–3 are the manufacturer, positions 4–8 describe the vehicle type and features, position 9 is a check digit, position 10 is the year, and positions 11–17 identify the specific vehicle.

Write down your VIN and circle or highlight the 10th character. Compare that character to the year code chart above. If your car is from 2010 or later, use the current 30-year cycle. If it's older, you may need to check your registration or contact the manufacturer to confirm the year, since the same letter code repeats every 30 years.

Some online VIN decoders will show you the year automatically when you enter your full VIN, which can be a quick way to double-check. However, the 10th digit alone is enough to tell you the year if you know which 30-year cycle your vehicle falls into.

Common confusion about the 10th digit

The most frequent mistake is assuming that a letter in the 10th position always means a recent car. Because the current cycle started in 2010, any car from 2010 to 2039 will have a letter in that position. But a car from 1980 to 2009 also has a letter in the 10th position — it's just from an earlier cycle. The letter A appears in both 1980 and 2010, so you must know the approximate age of the vehicle to interpret the code correctly.

Another source of confusion is the missing letters. The VIN code skips I and O to avoid confusion with 1 and 0. If you see an I or O in a VIN, that VIN is not valid — it may be forged or incorrectly transcribed. Always double-check that you've copied the VIN correctly, especially if you're reading it from a photo or a worn label.

Some people also confuse the 10th digit with the model year listed on the title or registration. The title shows the year the vehicle was registered or titled, which may be different from the year it was manufactured. A car manufactured in late 2009 might be titled as a 2010 model year. The VIN's 10th digit shows the actual manufacturing year, which is more precise for technical purposes.

Using the year code for parts and maintenance

When you order replacement parts, you'll usually need to provide your VIN or at least the year, make, and model. The 10th digit confirms the year portion of that information. If a parts supplier asks for your model year and you're unsure, decoding the 10th digit of your VIN gives you the answer directly from the manufacturer's code.

Maintenance schedules and service bulletins are also tied to model year. Your owner's manual covers the specific year of your vehicle, and knowing the exact year from your VIN ensures you're following the right maintenance intervals and procedures. This is especially important for vehicles with recalls or known issues that explore only to certain years.

If you're buying a used car and want to verify its age, the 10th digit of the VIN is one of the first things to check. Cross-reference it with the title, the odometer reading, and the overall condition of the vehicle. A mismatch between the VIN year code and the title year is a reason to investigate further before completing the purchase.

Frequently Asked Questions

What if the 10th digit is a number instead of a letter?

Numbers appear in the 10th position for vehicles manufactured from 2030 to 2039 in the current cycle. The code uses 0 for 2030, 1 for 2031, 2 for 2032, and so on through 9 for 2039. After 2039, the cycle repeats and starts over with A for 2040.

Can I use just the 10th digit to determine my car's year without knowing anything else?

Not reliably, because the same letter or number repeats every 30 years. You need to know the approximate age of the vehicle or have other information (like the title or registration) to match the 10th digit to the correct year. If your car is from 2010 or later, the current cycle applies.

Is the 10th digit the same as the model year on my title?

Usually, but not always. The VIN's 10th digit shows the manufacturing year, while the title may show the year the vehicle was first registered or titled. A car built in late 2009 might be titled as a 2010 model. The VIN is more precise for technical purposes.

What does it mean if the 10th digit doesn't match my registration?

A mismatch could indicate a data entry error on the registration, a title issue, or in rare cases, VIN tampering. If you notice a discrepancy, contact your state's motor vehicle department or the vehicle manufacturer to clarify the correct manufacturing year.

Do I need to know the 10th digit to get my car serviced?

No — your mechanic or service center can look up your full VIN in their system, and they'll see all the information they need, including the year. However, knowing the 10th digit yourself is useful if you're ordering parts independently or checking recall information online.
