The VIN tells you the model year in the 10th position
Your vehicle identification number (VIN) is a 17-character code stamped on your car's frame and listed on your title and insurance documents. The 10th character is a letter or number that represents the model year your car was manufactured. This single character can tell you whether your car was built in 1980, 2005, 2015, or any year in between.
The year code repeats every 30 years because there are only 30 possible characters (the letters I, O, Q, and Z are skipped). This means a car with a "Y" in the 10th position could have been made in 2000 or 1970. To narrow it down, you need to look at the first character of the VIN as well, which identifies the country where the car was built.
Key Takeaways
- The 10th character of your VIN is the model year code, and you can find your VIN on your title, insurance card, or the driver's side dashboard.
- The year code uses letters A through Y (skipping I, O, Q, and Z) and repeats every 30 years, so you may need the first character to confirm the decade.
- Cars made from 2010 onward use the letters A (2010), B (2011), C (2012) and continue through Y (2029), then restart at A in 2030.
- If the 10th character is a number, your car was made between 2001 and 2009, with 1 representing 2001 and 9 representing 2009.
Where to find your VIN
Your VIN appears in several places on your vehicle and in your paperwork. The easiest spot to check is your insurance card or policy documents — the VIN is always listed there. You can also look at your vehicle title or registration certificate.
On the car itself, the VIN is stamped into the metal on the driver's side of the dashboard, just below the windshield. You can read it from outside the car by looking through the windshield at the bottom left corner. The VIN also appears on the driver's side door jamb, usually on a sticker that lists tire pressure and other specifications.
How the year code works
The year-coding system uses 30 characters in this order: A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S, T, V, W, X, Y, 1, 2, 3, 4, 5, 6, 7, 8, 9. Notice that I, O, Q, and Z are left out. This pattern repeats every 30 years.
For cars built from 2001 to 2009, the 10th position uses numbers instead of letters. A "1" means 2001, a "2" means 2002, and so on through "9" for 2009. Starting in 2010, the system switched back to letters, with "A" representing 2010.
Since the code repeats every 30 years, a car with an "A" in the 10th position could be from 1980, 2010, or 2040. The first character of the VIN tells you the country of origin and helps narrow down the decade. Most cars sold in the United States have a "1", "4", or "5" as the first character.
Year codes for recent vehicles
If your car was made in the last 15 years, the decoding is straightforward. Cars built from 2010 to 2029 use letters A through Y in order. Here is how the recent years break down: A is 2010, B is 2011, C is 2012, D is 2013, E is 2014, F is 2015, G is 2016, H is 2017, J is 2018, K is 2019, L is 2020, M is 2021, N is 2022, P is 2023, R is 2024, S is 2025, T is 2026, V is 2027, W is 2028, and X is 2029.
In 2030, the cycle will restart with "A" again. This means that starting in 2030, you will need to look at other parts of the VIN or your registration to confirm whether a car with an "A" in the 10th position was made in 1980, 2010, or 2030.
What to do if you only have the year code
Sometimes you may have just the 10th character without knowing the full VIN or the car's actual age. In that case, you can make an educated guess based on the car's condition and mileage. A car that looks brand new and has low mileage with a "Y" in the 10th position was almost certainly made in 2000, not 1970.
If you need the exact year for a purchase, repair, or insurance reason, ask the seller or dealer for the complete VIN. You can also check your state's motor vehicle department website — most allow you to look up a vehicle's details using the full VIN, which will confirm the exact model year.
Why manufacturers use this system
The VIN year code is part of a standardized system adopted by all car manufacturers worldwide. This system, called the World Manufacturer Identifier (WMI) standard, makes it possible to track vehicles across borders and through their entire lifespan. Insurance companies, mechanics, and used car buyers all rely on this code to verify a vehicle's age and authenticity.
The 30-year cycle was chosen because it is long enough that most vehicles are no longer in regular use by the time the code repeats. A car made in 1980 is unlikely to be confused with one made in 2010 because the older vehicle would show its age in obvious ways.
Frequently Asked Questions
Can I find the exact month and year from the VIN?
The VIN tells you the model year, not the exact month. The 10th character only narrows it down to a calendar year. Some manufacturers include the build date elsewhere on the vehicle, such as on the engine block or inside the door jamb, but this information is not standardized across all brands.
What if the 10th character is a letter I, O, Q, or Z?
These letters are never used in the 10th position of a VIN. If you see one of these letters in that spot, the VIN may be incorrect or misread. Double-check that you are looking at the correct position and that you copied the VIN accurately.
Does the year code tell me anything about the car's features or engine?
No, the 10th character only indicates the model year. Other positions in the VIN identify the manufacturer, the type of vehicle, the body style, and the engine, but the year code itself does not reveal these details. You need the full VIN to get that information.
Why do some cars have numbers and others have letters in the 10th position?
Cars built from 2001 to 2009 use numbers (1 through 9) in the 10th position. Starting in 2010, manufacturers switched to letters (A through Y). This change was part of the standard VIN format update that took effect in 2010.
