Where is the VIN number in Hyundai i30 (III [2017-2021])?

This guide shows you the real-world VIN (chassis number) locations on the Hyundai i30 III (2017–2021) so you can confirm the vehicle identity quickly and avoid mixing it up with engine codes.

Chassis Number Locations

Front Floor (Chassis Stamp under carpet flap)

• Where to look: Slide the front seat back and check the interior floor under the seat. Look for a pre-cut carpet flap marked “FRAME NO”—lift the flap to reveal the VIN stamped into the chassis cross-member (metal floor structure).
• Access: Lighting is typically poor because the seat casts a shadow. You’ll likely need to move the seat backward for working room. Expect sand/dirt trapped around the flap—wipe/scrub before reading.
• Note: On many i30s this stamp is found on the right side of the car. For LHD vehicles that commonly means the passenger-side front footwell area, but if you don’t find it there, check the driver-side footwell/seat area as well.
• Tip: Because it’s dark and low-contrast stamped metal, use the flashlight and OCR to scan it directly with your phone instead of trying to squint and copy characters from an awkward angle.

Manufacturing Label (Door jamb / B-pillar sticker)

• Where to look: Open the front door and inspect the center pillar (B-pillar) door jamb where the door latches. You’re looking for a black or silver manufacturer sticker listing the VIN, paint code, and weight limits.
• Access: Usually easy to reach and well positioned, but the label can suffer from wear/fading over time. Bright sun can also create glare on the sticker.
• Note: This is a label (not a metal stamp). Use it for a quick read, but for identity checks it’s smart to compare it to the stamped floor VIN too.
• Tip: If glare or fading makes it hard to read, angle the phone slightly and use the VIN scanner so you don’t misread similar characters like B/8, S/5, or 0/O.

Common Problems & Troubleshooting

• “I can’t see the VIN under the seat.” That spot is often in deep shadow—slide the seat fully back, use a flashlight, and clean dirt/sand out of the carpet flap area before scanning/reading.
• “The stamped VIN looks faint.” The stamp can be low-contrast against body-colored metal; wipe it clean and view from an angle so the stamp relief casts a shadow.
• Sticker vs. stamped VIN: The B-pillar label can be damaged, replaced, or faded—always try to verify the VIN against the stamped chassis location for a stronger match.
