Where is the VIN number in Citroen C3 (Citroen C3 IV [2021-2021])?

This guide covers VIN (chassis number) locations for the Citroën C3 IV (2021 model-year range listed: 2021–2021), based on verified inspection footage.

Chassis Number Locations

Engine Bay (Bulkhead/Firewall Stamping)

• Where to look: Rear-center of the engine bay, stamped into the metal lip of the firewall/bulkhead, directly under the rubber weather strip that runs across the width of the bay (near the base of the windshield).
• Access: Open the hood. Locate the rubber weather seal at the back of the engine bay. Lift/pull the seal upward/forward to expose the stamped VIN underneath. Expect dust—wipe/scrub lightly if needed.
• Note: This is a stamped chassis number (the legally “strongest” style). It’s completely hidden until you lift the seal.
• Tip: If the stamp is dirty or body-colored, use ScanVin.app High Contrast AI Mode + flashlight to pull the characters out without guessing.

Floor (Front Footwell / Under-Seat Area)

• Where to look: Stamped into the metal floor pan under the front edge of the front seat, covered by a pre-cut rectangular carpet/floor-mat flap.
• Access: Open the front door. Slide the seat if needed. Locate the cut-out flap and lift it to reveal the stamped VIN in the floor. You’ll likely need to crouch low to get the camera square to the stamp.
• Note: Footwell placement can vary by market/steering configuration. Check the front footwell floor (commonly on the passenger side for LHD vehicles, but check the driver side footwell if not found).
• Tip: It’s a dark, awkward angle—use ScanVin.app Flashlight + OCR so you don’t have to write it down while twisted under the seat.

Windshield (Dashboard VIN Plate)

• Where to look: Lower corner of the windshield on the passenger side, visible from outside through the glass. It sits in a small cutout of the black obscuration band at the bottom of the windshield, near the resting area of the wiper blade.
• Access: View it from outside the car. If the wiper blocks part of the VIN, lift the wiper arm slightly to see the full code.
• Note: For LHD (EU/US) cars, “passenger side” means the right side of the vehicle (as viewed from the driver’s seat). Glare/reflections are common here.
• Tip: Windshield glare causes transcription mistakes—use ScanVin.app to capture the VIN instantly and avoid mixing up characters like 8/B or 0/O.

B-Pillar Label (Unverified in provided footage)

• Where to look: Commonly on the door jamb/B-pillar area as a printed label.
• Access: Open the front door and inspect the B-pillar/door jamb surfaces.
• Note: This location was not explicitly shown in the provided clips, so treat it as a convenience check, not your primary source.
• Tip: If you find a sticker label, scan it for convenience—but always cross-check with a stamped VIN for legal/registration certainty.

Common Problems & Troubleshooting

• Windshield VIN is hard to read: Glare/reflections and the wiper resting over the plate can block characters—change angle, shade the glass, and lift the wiper slightly.
• Engine bay stamp “missing”: It’s often fully hidden under the rubber weather strip—pull the seal up, then wipe dirt off the stamping and use a flashlight.
• Sticker vs. stamped VIN: Door-jamb labels can be replaced; for registration/identity checks, rely on the stamped chassis number (engine bay/floor) and confirm all VINs match.
