Where is the VIN number in Mercedes-Benz Klasa C (W203)?

This guide shows where to find the VIN (chassis number) on the Mercedes-Benz C-Class W203, produced between 2000–2006, including the common factory sticker and the stamped chassis locations.

Chassis Number Locations

B-Pillar (Door Sticker)

• Where to look: Open the front door and locate the black VIN/vehicle data sticker with white text on the B-pillar (door jamb)—the pillar where the door latch meets the body. It typically lists the VIN plus paint/weight codes.
• Access: Very easy access; usually well-lit. The main issue is fading, peeling, or paint-over after bodywork.
• Note: For LHD (EU/US) cars, check the left side of the car (driver’s door jamb). (The videos shown are RHD vehicles, where the sticker appears on the right/driver side for that market.)
• Tip: If the sticker text is small or partially worn, scan it directly with your phone using ScanVin.app to avoid misreading characters like B/8, S/5, 0/O.

Under Front Seat / Floor Cross-Member Stamp (Under Flap)

• Where to look: Check the front footwell floor at the seat mounting cross-member. Look for a rectangular carpet flap or hard plastic cover—lift/slide it to reveal the VIN stamped into the metal cross-member near the front edge of the seat rails.
• Access: Medium effort. You’ll need to slide the seat back, then lift the flap/trim. It’s commonly dark and dirty (shoe debris), so you may need to wipe/scrub the area to read the stamp.
• Note (LHD/RHD): This stamp is often found on the right side of the car. For LHD vehicles that can mean the passenger-side front footwell—but if you don’t find it there, check the driver-side footwell as well.
• Tip: Because this area sits in shadows under the seat, use ScanVin.app’s flashlight + OCR scan so you don’t have to twist awkwardly and manually copy the digits.

Engine Bay (Inner Wing/Firewall Area Stamp)

• Where to look: In the engine bay, look for a VIN/chassis stamping on the painted metal of the inner fender/inner wing near the battery/shock tower area. On many W203s it’s on the left side of the engine bay when you’re standing in front of the car.
• Access: Usually reachable with the hood open, but visibility can be blocked by hoses/lines/reservoirs, and the stamped characters can be dusty or greasy.
• Note: Don’t confuse the engine number (stamped on the engine block) with the VIN/chassis stamping on the body—they are different identifiers.
• Tip: If the stamp is dirty or the paint glare makes it hard to read, use ScanVin.app in high-contrast scanning mode to pull out faint characters without guessing.

Windshield (Dashboard VIN Plate)

• Where to look: From outside the car, check the lower corner of the windshield on the driver side, looking down at the dashboard area for a VIN display.
• Access: Easy to view—if present and unobstructed.
• Note: Reflections, the windshield’s dotted border, and the viewing angle can hide characters.
• Tip: If glare is washing out the digits, capture the VIN quickly with ScanVin.app instead of trying to read it through reflections and writing it down wrong.

Common Problems & Troubleshooting

• Under-seat floor VIN won’t read: Dirt + low light is the usual issue—slide the seat back, lift the flap fully, and scrub/wipe the stamping before scanning.
• Engine bay stamp is hard to see: Painted metal can glare and hoses can block the view—change angle, clean the area, and avoid confusing engine-number stampings with the chassis VIN.
• Sticker doesn’t match / looks tampered: Door-jamb stickers can be replaced after repairs—always cross-check at least two VIN locations (sticker + stamped body VIN).
