How to read a Infiniti Q45 VIN
Here is a real 2006 Infiniti Q45 VIN from our database, split into its parts:
VIN JNKBF01A56M800128 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |

Where Infiniti Q45 VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 2 Infiniti Q45 VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|
| JNK | Japan | — | 2 |
Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.

Where to find the VIN on a Infiniti Q45
A Infiniti Q45 VIN normally opens with JNK; the full number sits in four places, and all four must match.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |
