The 10th digit is your vehicle's model year, encoded as a letter or number
The 10th position in a Vehicle Identification Number (VIN) is a single character — either a letter or a number — that represents the year the vehicle was manufactured. This digit does not tell you when the car was sold or registered; it tells you when it rolled off the assembly line. A 2015 model year car might have been built in late 2014, and a 2020 model year might have been assembled in 2019.
Manufacturers use a repeating 30-year cycle to encode model years. The cycle runs from 1980 to 2009, then repeats: 2010 to 2039, then 2040 to 2069, and so on. This means the letter or number in position 10 alone does not tell you the century — you have to know the vehicle's approximate age or look at other VIN digits to pin down which cycle you are in. The 10th digit matters most when you are checking recall information, insurance records, or parts compatibility, because a part designed for a 2015 model may not fit a 2005 model, even if they are the same make and model.
Key Takeaways
- The 10th VIN digit encodes the model year using a letter-number cycle that repeats every 30 years, so you need to know the vehicle's approximate age to read it correctly.
- Model year is not the same as build year — a 2020 model may have been built in 2019, and the 10th digit reflects the model year, not the calendar year of manufacture.
- The model year in position 10 is critical for matching parts, checking recalls, and verifying insurance coverage, because specifications change year to year.
- You can cross-check the 10th digit against the 11th and 12th digits (the production sequence) and the first three digits (the manufacturer) to confirm you are reading the correct year.
How to read the 10th digit model year code
The 10th digit uses this pattern: the numbers 0 through 9 represent years, then the letters A through Y (skipping I and O to avoid confusion with numbers) represent the next years. The letter Z does not appear in the cycle. Once you reach Y, the cycle restarts at 0.
Here is the repeating sequence: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S, T, V, W, X, Y — then back to 0. That is 30 characters total, covering 30 model years before the pattern repeats. To find your vehicle's model year, locate the 10th character in your VIN, identify what it is, then count forward or backward from a year you know. If you know your car is a 2015 and the 10th digit is F, you now know that F = 2015. If you see a different car with F in the 10th position, it is either a 1985 model (F in the first 30-year cycle) or a 2015 model (F in the second cycle). The vehicle's overall condition and the first three digits (which identify the manufacturer) will tell you which.
The two 30-year cycles most people encounter
Most vehicles on the road today fall into one of two cycles. The first cycle ran from 1980 to 2009. The second cycle began in 2010 and runs through 2039. A third cycle will begin in 2040.

Use this table to match your 10th digit to the correct model year. If your vehicle's title says 2015, find 2015 in the right column and confirm the 10th digit is F. If the 10th digit does not match, either the VIN or the title may contain an error.
Why the 10th digit matters for recalls and parts
When you search for recalls on the National Highway Traffic Safety Administration (NHTSA) website or through your manufacturer's recall tool, the model year is one of the first filters. A recall issued for 2015 Honda Civics may not explore to 2014 or 2016 models because the affected component changed between years. The 10th digit is how you confirm which year you are looking at.
Parts catalogs also organize by model year. An engine part, transmission component, or electrical module designed for a 2015 model may have a different part number for a 2014 or 2016 model, even though the vehicles look nearly identical. Ordering the wrong year can mean the part does not fit or does not work correctly. The 10th digit is your first checkpoint. Insurance companies also use model year to calculate premiums and coverage limits. A 2015 model and a 2005 model of the same make and model will have different insurance rates because they have different safety features, repair costs, and depreciation curves. Providing the correct model year — which you can verify from the 10th VIN digit — ensures your quote and coverage are accurate.
How to verify you are reading the 10th digit correctly
The VIN is 17 characters long, and each position has a specific meaning. The first three digits identify the manufacturer and country of origin. Digits 4 through 8 describe the vehicle type, body style, engine, and transmission. Digit 9 is a check digit used to validate the entire VIN. Digits 10 and 11 are the model year and manufacturing plant. Digits 12 through 17 are the production sequence number.
If you are unsure whether you are reading the 10th digit correctly, cross-check it against what you know about the vehicle. If the title says 2015 and the 10th digit is F, that matches the table above. If the title says 2015 but the 10th digit is something else, either the title is wrong, the VIN is wrong, or you are counting the digits incorrectly. Count from left to right, starting at 1, and make sure you are looking at the 10th character, not the 9th or 11th. You can also verify the VIN using the check digit in position 9. The check digit is calculated using a weighted formula applied to all other digits. If the VIN fails the check digit test, the VIN itself may be altered or incorrect. Several free VIN decoder tools online will run this calculation for you and flag invalid VINs.
What the 10th digit does not tell you
The 10th digit tells you the model year, but it does not tell you when the vehicle was actually built. A 2015 model year vehicle might have been manufactured in September 2014 or as late as August 2015, depending on the manufacturer's production schedule. The 11th and 12th digits (the manufacturing plant and production sequence) can narrow this down further, but they do not give you an exact date.
The 10th digit also does not tell you the vehicle's condition, mileage, accident history, or service record. It is purely a year code. A 2015 model with 200,000 miles and a 2015 model with 30,000 miles have the same 10th digit, but they are very different vehicles in terms of wear and value. The model year is one piece of information among many you need to understand a vehicle's true age and condition.
Frequently Asked Questions
What if the 10th digit is a letter I or O?
The letters I and O never appear in the 10th position. The VIN system skips them to avoid confusion with the numbers 1 and 0. If you see an I or O in the 10th position, the VIN is either misread, mistyped, or altered. Double-check the VIN against your title or registration.
Can I tell if a car was built in 2015 or 2005 just from the 10th digit?
Not from the 10th digit alone. Both 2005 and 2015 models use the same letter or number in position 10 because the cycle repeats every 30 years. You need to know the vehicle's approximate age or check the first three digits (which identify the manufacturer) and the overall condition to determine which cycle you are in.
Does the 10th digit change if a vehicle is re-titled or re-registered?
No. The VIN is permanent and does not change when you transfer ownership, re-register, or renew your title. The 10th digit will always reflect the original model year the vehicle was manufactured, regardless of how many times it changes hands.
How do I find the VIN on my vehicle?
The VIN is printed on the driver's side dashboard at the base of the windshield, visible from outside the car. It is also on your title, registration, and insurance documents. On the dashboard, it is usually a 17-character string that you can read by looking through the windshield from outside.
What if my vehicle was built before 1980?
Vehicles built before 1980 use a different VIN format with only 11 or 13 characters, and the model year encoding is different. The 30-year cycle system described here applies only to vehicles from 1980 onward. If you have a pre-1980 vehicle, you will need to consult a classic car VIN decoder or contact the manufacturer directly.
