Where is the VIN number in Toyota Yaris (I [2003-2005])?

This guide shows you where to find the VIN (chassis number) on the Toyota Yaris I produced between 2003 and 2005, using the most consistent factory locations mechanics check.

Chassis Number Locations

Under Front Right Seat (Floor / Chassis)

• Where to look: Slide the front right seat fully back and look on the floor under the seat rails. Find a carpet cut-out flap (or, on some markets, a rigid plastic cover labeled “FRAME NO. / VIN”). Lift/pry it up to reveal the VIN stamped into the chassis/cross-member.
• Access: Medium. You’ll need to move the seat all the way back and work in a tight, dark space. The flap/cover can be stiff—use a trim tool or a flat screwdriver carefully so you don’t tear the carpet.
• Note: On LHD cars, this is commonly on the passenger side (front right). If you don’t find it there, check the opposite front footwell area as markets/trims vary.
• Tip: Because it’s dark and you’re working at an awkward angle, use the phone flashlight and OCR to avoid misreading characters—scan it directly with ScanVin.app.

B-Pillar / Door Jamb Label (Passenger Side)

• Where to look: Open the passenger door and check the B-pillar/door jamb for a black sticker with white text showing the VIN plus model/engine codes.
• Access: Low. No tools needed—just fully open the door and wipe dust off the label if needed.
• Note: This is a sticker label (not a metal stamp). It’s great for quick confirmation, but always compare it to a stamped VIN when inspecting a car.
• Tip: If you’re cross-checking multiple VIN points quickly, capture it with your phone using the VIN scanner instead of typing long strings.

Engine Bay (Bulkhead / Firewall Stamping)

• Where to look: Open the hood and look at the center of the firewall/bulkhead behind the engine, slightly below the windshield cowl line. The VIN is stamped directly into the metal and can sit deep in the recess.
• Access: High. This spot is usually shadowed by the cowl/engine components; you’ll need strong lighting and a steady hand to see the stamp clearly.
• Note: This is one of the “hard proof” stamped locations—worth checking when buying or verifying identity.
• Tip: If the stamping is faint or you can’t get your eyes in line with it, use ScanVin.app to scan it in-place so you don’t have to write it down while leaning into the engine bay.

Windshield (Dashboard Corner)

• Where to look: From outside the car, look through the bottom corner of the windshield on the driver’s side for the VIN plate visible through the glass.
• Access: Medium. Easy to reach, but glare/reflections on the windshield can hide characters.
• Note: Best used as a quick first check, then verify against the floor/firewall stamp.
• Tip: To beat glare and avoid transcription mistakes, scan the VIN instantly with your camera and let OCR pick out the characters.

Common Problems & Troubleshooting

• Too dark under the seat: Slide the seat all the way back, use a flashlight, and clean the stamped area lightly so the characters pop (dust hides shallow stamps).
• Firewall VIN is hard to see: Use a strong light and aim from above; don’t mistake casting marks for the VIN—Toyota stamps are clean, straight, and evenly spaced.
• Sticker mismatch warning: Door-jamb labels can be replaced; if the sticker VIN doesn’t match the stamped floor/firewall VIN, treat it as a serious red flag and verify the vehicle history.
