Where to find the VIN on a Mercedes-Benz GLS-Class
A Mercedes-Benz GLS-Class VIN normally opens with 4JG; the full number sits in four places, and all four must match.

|---|---|---|
| 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 |
