VIN Year Lookup — Find the Model Year by VIN
Need to confirm a vehicle's model year from the VIN? On every 17-character VIN the 10th character encodes the model year — a single position that settles the age of the vehicle when a title, listing or odometer claim is unclear. Enter a VIN to decode the year free.

On a 17-character VIN, the model year is encoded in the 10th character. Under the ISO 3779 standard used since 1981, that position follows a fixed cycle — letters A–Y (skipping I, O, Q, U, Z) and digits 1–9 — that repeats every 30 years. The 7th character (a letter vs. a digit) distinguishes the cycles, so a decoder returns the exact model year, not just a 30-year range.
What this lookup reveals
Model year from position 10
The 10th VIN character is the model-year code — the single position that fixes the vehicle's year.
Cycle disambiguation
Because year codes repeat every 30 years, the 7th character resolves which cycle applies.
Model year vs. build date
The VIN encodes the model year, which can differ from the calendar month the vehicle was actually built.
Standard since 1981
The fixed-position model-year code applies to every VIN issued under ISO 3779 from 1981 onward.

How the 10th character encodes the year
Since 1981 the VIN's 10th position has carried the model year on a defined cycle: the letters A through Y (omitting I, O, Q, U and Z because they're confused with numbers) cover 1980 through 2000, then the digits 1 through 9 cover 2001 through 2009, and the letters begin again. Because the sequence repeats every 30 years, an 'A' could mean 1980 or 2010 — which is why the rest of the VIN matters.
The 7th character resolves the ambiguity: on 1981–2009 vehicles it's a digit, and on 2010-and-later vehicles it's a letter. A decoder reads both positions together and returns the exact model year rather than a range.
Model year is not the same as the build date
The model year a VIN encodes is the year the manufacturer assigned to that production run — it isn't necessarily the calendar year the vehicle rolled off the line. A car built in late 2023 is commonly a 2024 model. The certification label on the driver-side door jamb shows the actual month and year of manufacture if you need the build date as well.
For everything else the year sits within — make, model, trim, engine and plant — decoding the full VIN returns the complete factory specification alongside the year.
Frequently Asked Questions
Which VIN digit is the year?
The 10th character of a 17-character VIN encodes the model year. A decoder reads it together with the 7th character to return the exact year.
Can two different years share the same VIN year code?
Yes. Year codes repeat every 30 years, so the same 10th-character code can mean two years 30 years apart. The 7th character (a digit before 2010, a letter from 2010) tells the cycles apart.
Is the model year the same as the year it was built?
Not always. The VIN encodes the model year the manufacturer assigned, which can differ from the calendar build date. The door-jamb certification label shows the actual month and year of manufacture.
Why are some letters missing from year codes?
The letters I, O, Q, U and Z are skipped because they're easily confused with the numbers 1, 0 and 2. That's why the model-year sequence runs A–Y rather than A–Z.
Is a VIN year lookup free?
Yes. Decoding the model year from a VIN is free here, with no signup.
