Where is the VIN number in Mazda 3 (IV [2019-2019])?

This guide covers the VIN number locations for the Mazda 3 IV produced between 2019–2019, including the easiest scan points and the hidden chassis stamp used for legal verification.

Chassis Number Locations

B-Pillar / Door Jamb (Certification Label)

• Where to look: Open the driver’s door and look on the B-pillar (the post between the front and rear doors), near the door latch mechanism. You’ll see a black or white sticker with the VIN plus tire pressure and paint code details (often with a barcode).
• Access: Low difficulty. Typically clean and well-lit with the door open, but the barcode can get worn from age/seatbelt strikes.
• Note: This is usually the best primary scanning target because it has strong contrast and often includes a barcode.
• Tip: If the barcode is scuffed or the print is faded, **use a close, steady shot and let the camera do the work—**you can scan the label instantly with your phone instead of trying to read damaged characters.

Windshield / Dashboard (Visible VIN)

• Where to look: From outside the car, look through the lower corner of the windshield on the driver’s side. The VIN is on a metal plate riveted to the dashboard cowl.
• Access: Medium difficulty. The VIN is visible, but glare/reflections can be high depending on sun angle and dashboard texture.
• Note: In some markets the windshield VIN may be absent/blank; if you don’t see it, move straight to the door-jamb label or the floor stamp.
• Tip: When glare washes out the numbers, change your angle and distance, then capture the VIN cleanly with the camera scanner instead of manually squinting through reflections.

Floor / Chassis Stamp (Hidden Location)

• Where to look: Check the front right-side footwell floor area (commonly the passenger side on LHD vehicles). Look for a plastic cover/flap or a pre-cut carpet section marked like “VIN” or “FRAME NO”, then lift the flap / pull back the carpet to reveal the VIN stamped into the chassis metal.
• Access: High difficulty. It’s dark, you must physically lift a cover, and the stamping can be dirty/rusty from debris.
• Note: To avoid driver/passenger confusion across markets: this stamp is described as being on the right-hand side footwell. If you don’t find it there, check the opposite footwell as well.
• Tip: Turn on a light and get the camera close—then use the flashlight + OCR scan so you’re not trying to read a stamped code in shadows while bent over.

Infotainment System (Digital VIN)

• Where to look: On the center screen, use a menu path similar to: Information → Vehicle Status Monitor → Maintenance (exact wording varies by system/region).
• Access: Medium difficulty. Ignition must be ON and menus vary; scanning screens can introduce flicker/moiré.
• Note: Treat this as verification only—it’s not as trustworthy as the physical label/stamp for inspections and paperwork.
• Tip: If the screen flickers in photos, pause and hold steady—then scan and confirm the VIN carefully to avoid a one-character mistake.

Common Problems & Troubleshooting

• Windshield glare/reflections: Move your body angle left/right and reduce distance to the glass; reflections from the dash can hide characters.
• Hidden floor stamp is hard to see: Lift the flap/cut-out fully, use a flashlight, and wipe dirt off the stamping before trying to read it.
• Door jamb sticker integrity: If the label is torn, repainted over, or missing, don’t rely on it alone—cross-check with the floor/chassis stamp.
