Where is the VIN number in Toyota Prius II (NHW20)?

This guide covers the VIN (chassis number) locations for the Toyota Prius II (NHW20) produced between 2009–2009. If you’re verifying a car for registration, inspection, or purchase, always match the stamped body VIN to the VIN on the label.

Chassis Number Locations

Firewall / Cowl Panel (Engine Bay)

• Where to look: Open the hood and go to the rear of the engine bay. On the metal firewall/cowl panel, the chassis number is stamped into the metal under a small rectangular plastic trim cover. Carefully slide/lift the plastic cover to reveal the stamping underneath.
• Access: Moderate. You’ll need to lean over the engine bay; the trim can be brittle on older cars, so pry gently. A flashlight helps because the cowl area is usually shaded.
• Note: The reference footage is RHD, where it appears slightly off-center toward the passenger side. On LHD cars, use the same “rear of engine bay under the cowl cover” reference point—just mirror left/right as needed.
• Tip: Because it’s recessed and shadowed, use the app to scan it directly with your phone after turning on good lighting so you don’t misread faint stamped characters.

Manufacturer’s Label (B-Pillar / Door Jamb)

• Where to look: Open the front door and check the lower section of the B-pillar/door jamb for a black manufacturer sticker with white text listing the VIN and vehicle info.
• Access: Low difficulty. No tools needed—wipe dust off the label if it’s dirty.
• Note: Depending on market, the label may be on the left or right B-pillar. Use the vehicle-direction reference (left/right as you sit facing forward) rather than assuming “driver side.”
• Tip: This is high-contrast (white on black), so use the free VIN reader to capture it cleanly and avoid transcription errors.

Engine Block (Engine Number)

• Where to look: Locate a flat machined pad on the engine block where the engine number is stamped. On the Prius, it’s often visible from above but can be partly hidden by hoses or wiring looms.
• Access: Very high difficulty. Expect grease, dirt, or corrosion, and you may need to scrub the pad with a rag and mild degreaser to read it.
• Note: This is typically an engine number, not the primary body VIN—use it as a secondary verification point.
• Tip: If the stamping is faint/dirty, take a close photo and capture it with the high-contrast scanner so the characters stand out better than they do by eye.

OBD II Port (Diagnostic Connector)

• Where to look: Under the dashboard on the left side (driver area on LHD), find the standard OBD-II port under/near the steering column area.
• Access: Not a physical VIN stamp—this is for diagnostics. Easy to reach but cramped.
• Note: Useful for reading VIN via compatible scan tools/dongles (where supported), but always confirm against a body VIN location.
• Tip: If you’re in an awkward crouched position under the dash, scan the VIN label first to avoid writing numbers down in a tight space.

Common Problems & Troubleshooting

• Cowl cover won’t move / feels brittle: Don’t force it—lift/slide gently and work along the edges. Older trim can crack; warming the area slightly (sunlight) can help.
• Stamped numbers hard to read (shadow/oxidation): Use a flashlight, change your viewing angle, and wipe/scrub the metal lightly to remove dust or surface grime.
• Door-jamb sticker missing or damaged: Labels can be replaced or fade—treat the stamped body VIN as the key verification point and confirm it matches paperwork.
