Where is the VIN number in Opel Astra F (F)?

This guide covers where to find the VIN (chassis number) on the Opel Astra F (F) produced between 1998–1998, including the most common hidden stamped location and a secondary ID spot in the engine bay.

Chassis Number Locations

Front footwell floor VIN stamp (under plastic flap at door sill)

• Where to look: Open the front right door (front passenger side on many LHD cars). Look on the floor between the front seat and the door sill for a rectangular plastic trim flap designed to lift. Pry/lift the flap to reveal the VIN stamped into the chassis metal.
• Access: Low to Medium difficulty. Easy to reach, but the stamp can be dusty, rusty, or dirty—wipe/scrub the metal lightly until characters are sharp.
• Note: For LHD vehicles, this stamped floor VIN is commonly on the passenger side; if you don’t find it there, check the driver-side front footwell as well.
• Tip: If the stamp is dusty or sitting in a dark footwell, use the flashlight and OCR to scan it directly with your phone instead of guessing letters/numbers from a faint stamping.

Engine number (stamped on engine block, deep in engine bay)

• Where to look: Pop the hood and locate the engine block stamping on a vertical flat surface deep in the bay—down in the gap between the engine block and radiator fan shroud, slightly to the right of the exhaust heat shield when standing in front of the car.
• Access: High difficulty. The number is deep and awkward to view, with poor lighting and often grease/road grime on the block. You may need to angle your phone down into a tight gap and wipe the surface clean first.
• Note: This is typically the engine number/engine ID, not the body VIN—use it to cross-check documents or engine swaps.
• Tip: Because it’s hard to reach and usually greasy, scan the stamping with your phone to avoid writing it down from an uncomfortable angle, and use high-contrast capture if characters are faint.

Common Problems & Troubleshooting

• Floor VIN looks “missing”: It’s often under a small trim flap and can be packed with dust—lift the flap fully and clean the metal stamping before re-checking.
• Engine stamping unreadable: The engine number is deep in shadows and commonly greasy—use a rag + brake cleaner (carefully) and re-check with angled lighting.
• Don’t rely on stickers alone: Door/engine-bay stickers can be replaced—always prioritize the stamped chassis VIN when verifying the vehicle.
