Mitsubishi Montero VIN prefixes, and when each one was used
Every Mitsubishi Montero we have on record, from 1986 to 2006, opens with the same three characters, JA4:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| JA4 | 1986–2006 | Japan | Multipurpose Passenger Vehicle (MPV) |
Position 11 names the plant. On the Mitsubishi Montero it is not one number either — assembly moved between 3 of them over the years:

Where to find the VIN on a Mitsubishi Montero
A Mitsubishi Montero VIN normally opens with JA4; 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 |
