Position to check
10th character
Count from the left side of the VIN.
Vehicle lookup
Use the 10th character of a 17-character VIN to identify the model-year code, then verify the decoded year with the full VIN decoder and NHTSA vPIC attributes.

The model-year code is position 10 of a standard 17-character VIN. The code repeats on a 30-year cycle, so a single character should be read with vehicle age, listing context and NHTSA decode results.
Enter a 17-character VIN here, then use the examples and notes below to understand what the result can and cannot prove.
| Scenario | Result | Interpretation |
|---|---|---|
| 1HGCM82633A004352 | 2003 Honda Accord | The 10th character is 3, matching the tested Honda example. |
| 2T1BURHE4JC034340 | 2018 Toyota Corolla | The 10th character is J, matching the tested Toyota example. |
| 5YJ3E1EA2KF317000 | 2019 Tesla Model 3 | The 10th character is K, matching the tested Tesla example. |
10th character
Count from the left side of the VIN.
30-year cycle
Model-year codes repeat, so use the full decoder for context.
Match documents
The decoded year should make sense beside title, registration and listing details.
model year code = VIN character 10
The 10th character encodes model year for modern 17-character VINs. Because codes repeat, the decoder uses the full VIN and context rather than treating one character as absolute proof.
| Metric | Formula | Use when |
|---|---|---|
| 10th character | VIN[9] | Find the model-year code quickly. |
| Full VIN decode | NHTSA vPIC DecodeVinValues | Confirm make, model and year together. |
| Registration check | seller documents | Confirm the decoded year matches title and registration. |
| Recall check | year + make + model + VIN | Check campaigns that apply to a specific model year. |
Usually the 10th character is the model-year code, but it repeats on a 30-year cycle and should be checked with the full VIN.
Not always. A vehicle can be built before its model year, so use manufacturer and registration records when timing matters.
