The 10th digit is your vehicle's model year
The 10th digit in a Vehicle Identification Number (VIN) represents the model year of your vehicle. This single character encodes which year the car was manufactured, using a repeating letter code that cycles through the alphabet. The digit appears in the 10th position when you read the VIN from left to right.
Manufacturers use this standardized system so that anyone — a mechanic, insurance company, or used car buyer — can determine a vehicle's age at a glance. The model year is not always the same as the calendar year the car was built. A 2024 model year vehicle, for example, may have been manufactured in late 2023.
The model year code has been in use since 1981 and follows a fixed pattern. The letters A through Y represent years (the letter I is skipped to avoid confusion with the number 1). After Y, the cycle restarts with A, meaning the code repeats every 30 years.
Key Takeaways
- The 10th digit of a VIN is a single letter that identifies the model year of your vehicle.
- The model year code uses letters A through Y in a repeating 30-year cycle, with I omitted.
- A vehicle's model year may differ from its actual build date — model year 2024 cars can be built in late 2023.
- You can use the 10th digit to verify a vehicle's age before buying used or to check if your car falls within a recall period.
How to locate and read the 10th digit
Your VIN is a 17-character code. To find the 10th digit, count from the left: the first nine characters are manufacturer and vehicle details, and the 10th character is the model year. You can find your VIN in several places on your vehicle: on the dashboard at the base of the windshield on the driver's side, on the driver's side door jamb, or on your vehicle registration and insurance documents.
Once you locate your VIN, count to the 10th position. That single letter is your model year code. For example, if your VIN is 1HGCV41JXMN109186, the 10th digit is M, which represents 1991 (or 2021, depending on the vehicle's actual age and the 30-year cycle).
The model year code chart
The following table shows which letters correspond to which years. Because the code repeats every 30 years, a letter can represent two different decades. You will need to know the approximate age of your vehicle or cross-reference with other VIN sections to determine which cycle applies.
| Letter | Year (First Cycle) | Year (Second Cycle) |
|---|---|---|
| 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 |
Notice that the letter I is not used in the code. This was an intentional choice by the National Highway Traffic Safety Administration (NHTSA) to prevent confusion between the letter I and the number 1 when reading VINs quickly or in poor lighting.
Why the model year matters for vehicle owners
Knowing your vehicle's model year from the VIN is useful for several practical reasons. Insurance companies use it to calculate premiums, as older vehicles often cost less to insure. Mechanics use it to order the correct parts and understand which safety features and emissions systems your car has. Buyers of used vehicles use it to verify that the seller's stated age matches the VIN.
The model year also determines whether your vehicle falls within a manufacturer recall. Recalls are often limited to specific model years or ranges of years. If you receive a recall notice, you can verify whether your car is affected by checking the 10th digit against the recall's model year range.
Additionally, some states base registration fees or emissions testing requirements on model year. Older vehicles may have different inspection standards or be exempt from certain regulations, so the 10th digit can affect your compliance obligations.
Distinguishing model year from build date
The model year code tells you when the vehicle was designed and first produced, not necessarily when your specific car rolled off the assembly line. A 2024 model year vehicle may have been built in September 2023, and a 2023 model year vehicle may have been built in early 2023 or late 2022.
If you need the exact build date, you will have to look elsewhere in the VIN or on the door jamb label. The 11th and 12th digits of the VIN represent the sequential production number, and the door jamb label (usually on the driver's side) often includes the actual month and year of manufacture. This distinction matters most when a vehicle is very new or when you are troubleshooting a problem that may be related to a specific production run.
Using the 10th digit when buying or selling a used vehicle
When you are considering a used vehicle, the 10th digit is one of the first things to check. It should match the seller's stated model year. If the seller says the car is a 2015 model but the 10th digit shows L (which represents 1990 or 2020), that is a red flag. A mismatch may indicate odometer fraud, title washing, or a salvage vehicle that has been rebuilt.
You can also use the model year to research common problems, typical maintenance costs, and safety ratings for that specific year. Some model years are known for particular defects or recalls, and knowing the year helps you ask informed questions before you buy.
Frequently Asked Questions
What if the 10th digit is a number instead of a letter?
The 10th digit should always be a letter, not a number. If you see a number in that position, the VIN may be invalid or incorrectly transcribed. Double-check that you are counting from the correct starting position and that you have copied the VIN accurately from your vehicle or documents.
Can I use just the 10th digit to determine the exact year?
Not always. Because the code repeats every 30 years, a single letter can represent two different decades — for example, M could mean 1991 or 2021. You will need to know approximately how old the vehicle is or cross-reference other parts of the VIN to determine which cycle applies. For vehicles built after 1980, the 2000s and 2010s cycles are most common.
Does the model year affect my insurance rates?
Yes, model year is one factor insurance companies use to calculate premiums. Newer vehicles often have better safety features and lower repair costs, which can lower your rate. Older vehicles may be cheaper to insure if they are paid off, but high-performance or luxury models from any year can be expensive to insure.
What if the VIN has been altered or is hard to read?
If the VIN on your dashboard is damaged or unclear, check the door jamb label on the driver's side or your vehicle registration and insurance documents. If multiple sources show different VINs or if you suspect the VIN has been tampered with, contact your state's motor vehicle department or a law enforcement agency.
How do I know if my car is affected by a recall?
You can search the NHTSA website (nhtsa.gov) by entering your VIN. The search will show all recalls issued for your specific vehicle, including the model years covered. Recalls are often limited to certain model year ranges, so the 10th digit helps determine whether your car is included.
