| 9 | Check digit, used to catch typos |
| 10 | Model year |
| 11 | Assembly plant |
| 12–17 | Production sequence number |
Where to find the VIN
- Bottom of the windshield on the driver's side, readable from outside.
- Sticker on the driver's door jamb.
- Title, registration and insurance card.
Why shops decode the VIN first
The right parts depend on the exact engine and trim, not just the model. Decoding the VIN at check-in avoids ordering the wrong brake rotors for a car that has two options. Put the VIN on every repair order and invoice.
Questions
Is this VIN decoder free?+
Yes. It uses the U.S. government's NHTSA vehicle database. No sign-up and no limits for normal use.
Does it show accident or title history?+
No. A VIN decoder tells you how the vehicle was built. Accident, title and odometer history come from paid history reports.
Why does a VIN never contain I, O or Q?+
To avoid confusion with 1 and 0. If you see one of those letters, it's almost certainly a 1 or 0.
Which character is the model year?+
The 10th character. Letters and numbers cycle every 30 years, so the decoder also uses other characters to pick the right year.
