Quick response
Quick Answer: The most reliable VIN location for the Opel Astra G is the stamped VIN on the front footwell floor under a rectangular plastic flap (commonly passenger side on LHD cars). It’s stamped into the chassis metal under the carpet trim—bring a flashlight because it’s usually dark and often dirty down there.

Where is the VIN number in Opel Astra (G) [1999-2003]?
This guide shows you exactly where to find the VIN (chassis number) on the Opel Astra G, produced between 1999–2003, using the quickest real-world locations you can access without dismantling the car.
Chassis Number Locations
1) Front footwell floor stamping (under carpet flap) 
- Where to look: The VIN is stamped directly into the chassis metal on the floor panel between the front passenger seat and the door sill, hidden under a rectangular plastic flap built into the carpet trim.
- Access: Open the front passenger door, locate the rectangular plastic cutout near the sill/seat rail area, then lift/pry up the plastic flap. Use a light—this area is often dark, and dirt can pack into the stamped characters (you may need to wipe/scrub it clean).
- Note: On LHD cars this is commonly on the passenger-side front footwell; if you don’t find it there, check the driver-side footwell as well (some markets/variants differ).
- Tip: If the stamping is in shadow or packed with dirt, use the app’s flashlight and OCR to scan the VIN directly instead of guessing letters/numbers.
2) Manufacturer label on the B-pillar (passenger side) 
- Where to look: A black manufacturer sticker/label on the lower B-pillar (center pillar) on the passenger side, typically showing the VIN plus weight data.
- Access: Open the front passenger door and look at the bottom of the B-pillar, just above the rocker panel. The label can be glossy (glare) and may peel/fade from foot traffic.
- Note: Sticker locations are handy for quick checks, but the stamped floor VIN is harder to tamper with and is the better “identity” check when buying.
- Tip: To avoid glare and transcription mistakes, capture it with your phone using the VIN scanner and let OCR read it cleanly.

Common Problems & Troubleshooting
- VIN stamping looks “missing”: It’s usually just buried under the mat/carpet flap or filled with grit—lift the flap fully and clean the metal stamping so the characters aren’t packed with dirt.
- Hard to read in the footwell: The floor VIN sits in a dark, awkward spot—use a flashlight and change your viewing angle to bring out the stamped depth.
- Sticker doesn’t match / is damaged: B-pillar labels can fade, peel, or be replaced; for purchase/identity checks, always compare against the stamped chassis VIN.
