Want to check a chassis number? Start by finding the stamping or VIN plate—windscreen base, driver’s door jamb, engine bay, or on the frame for older utes and bikes.
Make sure it matches the rego papers, and that plates, fonts, and rivets look factory rather than “made in shed.”
In Australia, use the 17‑digit VIN (or older chassis number) to run a PPSR search (about $2) for finance owing, write‑off and stolen status, and keep the certificate.
You can also do a free state rego check to confirm registration, but it won’t show encumbrance.
If digits are missing, over-stamped, or inconsistent across locations, walk away—no bargain beats a seized asset.
