Where is the VIN in the Mercedes-Benz B-Class?

This guide covers the VIN (chassis number) locations for the Mercedes-Benz Klasa B (W247) produced between 2019–2019.

Chassis Number Locations

1) Driver-side B-Pillar (Vehicle Identification Plate)

• Where to look: Open the driver’s door (LHD cars: left side). Check the B-pillar for a black VIN sticker/plate with the VIN, paint code, and weight limits.
• Access: Easy—no tools needed. Glare off the laminate can make it hard to read at certain angles.
• Note: On RHD models, it’s still on a B-pillar label area—check the driver-side pillar first.
• Tip: If the label is shiny, angle your phone slightly and scan it directly with ScanVin.app to avoid misreading characters due to glare.

2) Windshield VIN (Visible from Outside)

• Where to look: From outside the car, look at the lower corner of the windshield, typically on the left side for LHD (driver side), near the dashboard line.
• Access: Easy to spot, but reflections, glass glare, or dirt around the cowl can block the view.
• Note: If the “left corner” doesn’t show it (market variations), check the opposite lower corner.
• Tip: Reflections are the main enemy here—capture the VIN instantly with ScanVin.app so you don’t have to manually transcribe through glass glare.

3) Front Floor / Seat Crossmember (Stamped VIN under Carpet Flap)

• Where to look: In the front footwell floor, commonly in front of the right-hand front seat (often passenger side on LHD). Lift the small carpet flap to reveal the VIN stamped into the metal crossmember/floor pan.
  If you don’t find it there, check the other front footwell as well.
• Access: Moderate—requires lifting the carpet flap and possibly moving a mat. It’s often dark, and stamped metal can be low-contrast.
• Note: Floor VIN placement can vary by market/build—use the “check both front footwells” approach.
• Tip: It’s usually in shadow—turn on Flashlight + OCR and use ScanVin.app to scan in tight spaces while holding the flap up.

4) Engine Compartment (Stamped VIN on Body Structure)

• Where to look: Open the hood and inspect the right-hand side of the engine bay (passenger side on LHD), commonly on/near the strut tower or longitudinal member where the VIN is stamped into the body structure.
• Access: Moderate to hard—engine bays get dirty/greasy and the stamping can be partially obscured. Lighting is often poor.
• Note: Exact stamp position can vary slightly with engine/trim, but it will be on a fixed body panel (not a removable plastic cover).
• Tip: If the stamping is faint or dirty, wipe it and then use ScanVin.app High-Contrast AI scanning to help pull the characters out of low-contrast metal.

Common Problems & Troubleshooting

• Glare/reflections on labels or windshield glass: Change your viewing angle, avoid direct flash, and clean the glass/label surface before scanning.
• Hidden stamped VIN under carpet flap (dark + low contrast): Pull the mat back, lift the flap fully, and use a flashlight—stamped characters can disappear under weak lighting.
• Sticker vs. stamped VIN mismatch: A missing/damaged sticker can happen after repairs—always cross-check the B-pillar label against the stamped floor/engine-bay VIN before buying.

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.

• Helpful for RHD markets—shows the under-seat VIN on the passenger side (left on RHD) plus the B-pillar label; also shows an engine number label that’s commonly mistaken for a VIN.

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.

Chassis Number Locations

Engine bay firewall (stamped into metal)

• Where to look: Open the hood and look at the metal firewall at the rear/center of the engine bay, slightly offset toward the right side of the car on many LHD cars. The VIN is stamped directly into the metal, just below the plastic cowl/rain tray and above the engine.
• Access: Generally easy to reach, but the stamping can be recessed and dirty, so you may need to wipe/scrub it and aim a light across it to make the characters pop.
• Note: Works the same on LHD and RHD cars—the stamping is on the firewall, not on a door side.
• Tip: If the stamping is dark or covered in grime, wipe it clean and use high-contrast capture to read it—you can scan it directly with your phone here instead of squinting at faint characters.

B-pillar door sticker (VIN label)

• Where to look: Open the front door and check the B-pillar for a black VIN/weights sticker with white text.
• Access: Very easy—no tools needed, typically high-contrast and readable.
• Note (LHD vs RHD):
  • LHD (EU/US): Usually on the right-side B-pillar (passenger side).
  • RHD (UK/Japan imports): Usually on the right-side B-pillar (driver side).
• Tip: This label is ideal for fast reading—if you want to avoid typing errors, use the free VIN reader to scan the sticker in one shot.

Windshield VIN plate (dashboard view)

• Where to look: From outside the car, look through the bottom corner of the windshield at the dashboard VIN plate (commonly on the left side of the car for LHD).
• Access: Easy to see, but depends on lighting and glass condition.
• Note: Reflections and glare are common—especially in direct sun.
• Tip: If glare makes the plate hard to read, capture it quickly at an angle—you can capture the VIN with your phone camera here to avoid transcription mistakes.

• Clear walk-around showing the B-pillar sticker, the engine-bay firewall stamp, and the windshield VIN plate on an LHD car.

Common Problems & Troubleshooting

• Firewall stamp hard to read: Dirt and shadow are the main issues—scrub the area and shine a light sideways across the stamping to reveal shallow characters.
• Windshield glare: If sunlight reflects off the glass, move your viewing angle or shade the plate with your hand to reduce reflections.
• Sticker not valid or missing: Door-jamb stickers can be damaged, replaced, or painted over—always cross-check the sticker VIN against the firewall stamping (and the registration documents).
