Where is the VIN number in Opel Insignia (B) [2017-2020]?

This guide covers the VIN (vehicle identification number) locations on the Opel Insignia B produced between 2017 and 2020, so you can quickly verify the chassis number for registration, insurance, or a pre-purchase check.

Chassis Number Locations

1) Driver’s-side B-pillar manufacturer sticker

• Where to look: Open the driver’s door and look at the lower section of the B-pillar (door jamb area). You’ll see a black manufacturer label/sticker with the VIN printed clearly in the center block.
• Access: Very Low difficulty. No tools needed—just open the door. Wipe dust off the sticker if it’s dull.
• Note: The inspected car is LHD (left-hand drive), so this is shown on the driver’s side (left side of the vehicle).
• Tip: Because it’s flat and high-contrast, you can usually scan it directly with your phone in one shot to avoid mis-typing characters.

2) VIN plate visible through the windshield (dashboard corner)

• Where to look: From outside the car, look through the lower corner of the windshield on the driver’s side, where the glass meets the dashboard/cowl area. The VIN plate is embedded in the dash and readable through the glass.
• Access: Low to Medium difficulty. The main issue is glare/reflections on the windshield, plus dirt collecting in that corner.
• Note: On LHD cars, this is shown on the driver’s side (left) at the base of the windshield.
• Tip: If reflections wash out the numbers, change your viewing angle and capture it with your phone using the VIN scanner so you don’t have to transcribe it through glare.

3) Engine bay VIN stamp on the firewall/bulkhead

• Where to look: Pop the hood and locate the firewall/bulkhead at the rear of the engine bay, just below the windshield cowl/scuttle panel. The VIN is stamped into the metal on the firewall ledge (slightly recessed and partially shadowed by the cowl/weather stripping).
• Access: Medium difficulty. It can be dark and recessed; grime/dust can fill the stamped characters. You may need a flashlight and a rag/brush to clean the stamp.
• Note: This location is consistent across the Insignia B shown (Sports Tourer and Grand Sport body styles).
• Tip: If the stamp is low-contrast or dirty, wipe it and use High Contrast scanning with ScanVin.app to pick up stamped characters that are hard to read by eye.

Common Problems & Troubleshooting

• Windshield VIN unreadable: Glare/reflections or dirt in the lower corner can hide characters—change angle, shade the glass, and clean the corner.
• Engine bay VIN stamp hard to decipher: Dust/grease and shadows reduce contrast—scrub the stamp lightly and use a flashlight for raking light across the characters.
• Sticker vs. stamped VIN mismatch: A damaged/removed door-jamb sticker can be misleading—always cross-check with the windshield VIN and the firewall stamped VIN when verifying identity.
