Where to find the VIN on a Mercedes-Benz GLB-Class
A Mercedes-Benz GLB-Class VIN normally opens with W1N; 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 |

What does position 4 mean on a Mercedes-Benz GLB-Class VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 47 Mercedes-Benz GLB-Class VINs here, 4 is the most common character in position 4, on 100% of them.
What if the VIN on the dashboard doesn't match the door jamb?
