Where is the VIN number in Mercedes-Benz Klasa B (W246)?

This guide covers where to find the VIN (chassis number) on the Mercedes-Benz B-Class / Klasa B (W246) produced between 2012–2013.

Chassis Number Locations

1) B-Pillar VIN Label (front passenger door open)

• Where to look: Open the front passenger door and look at the lower section of the B-pillar (the pillar between the front and rear doors). You’ll see a black sticker label with the VIN plus paint/weight data, often with a barcode/QR.
• Access: Easy access, no tools. If it’s dusty or scuffed, scrub gently with a microfiber cloth so the characters aren’t broken up by dirt.
• Note: This location is consistent across markets; sticker layout can vary (some imports show extra market-specific text).
• Tip: If the sticker is dirty or the print looks “broken,” use the free VIN scanner to capture it cleanly from the barcode/text instead of trying to read worn characters.

2) Stamped VIN under the front passenger seat (floor cross-member)

• Where to look: The VIN is stamped into the metal floor cross-member under the front passenger seat. Slide the seat back, then lift the pre-cut carpet flap (or unclip a small trim cover) to reveal the stamped characters.
• Access: Moderate difficulty. You must move the seat, lift carpet/trim, and you’re working in a tight, dark footwell. The stamp can be low-contrast if it’s dusty or painted body-color.
• Note: The stamped VIN is commonly on the passenger side for LHD cars (right side); on RHD cars it swaps to the passenger side (left side). If you don’t find it, check the opposite front footwell.
• Tip: Because it’s dark under the seat, use ScanVin’s Flashlight + OCR VIN reader to pick up the stamped characters without fighting shadows.

3) Windshield VIN plate (bottom corner of windshield)

• Where to look: From outside the car, look through the glass at the bottom corner of the windshield (typically the driver-side corner). The VIN is visible on the dashboard area.
• Access: Variable. Easy to reach, but glare, reflections, water spots, or tint can make the VIN hard to read or photograph.
• Note: Not every regional spec shows it the same way, but it’s common on EU/US market cars.
• Tip: If glare keeps washing out the numbers, capture it quickly with your phone using the ScanVin VIN scanner so you don’t mistype characters like 8/B or 5/S.

4) Engine bay label (engine number—often confused with VIN)

• Where to look: In the engine bay you may find a printed label on the engine cover showing an Engine No. (engine serial) and part information.
• Access: Easy to see with the hood open, but high confusion risk—this is usually not the vehicle VIN.
• Note: Use this for engine identification; for the actual VIN, rely on the B-pillar label, under-seat stamp, and windshield.
• Tip: If you’re unsure whether you’re looking at a VIN or an engine serial, scan it with the VIN reader tool—a real VIN will decode to vehicle details, while an engine number won’t.

Common Problems & Troubleshooting

• Under-seat stamped VIN is hard to see: Slide the seat fully back, lift the carpet flap, and use a bright light—dust and body-color paint can hide the stamp.
• Windshield VIN won’t scan/read: Clean the glass inside/out and change your angle to reduce glare/reflection.
• Sticker vs. stamped VIN mismatch: If the B-pillar sticker looks tampered, damaged, or missing, verify against the stamped VIN before you buy—stickers can be replaced.
