A VIN check uses a car’s 17-character Vehicle Identification Number to reveal what a seller might not tell you — whether there’s money still owing on it, whether it’s been written off or stolen, and other reported history. Running a VIN number check before you buy a used car is the single cheapest way to avoid buying someone else’s problem.
What is a VIN?
The VIN (Vehicle Identification Number) is a unique 17-character code stamped on every road vehicle. It’s the identifier used to look a car up on official registers. Don’t confuse it with the number plate — plates can change, but the VIN stays with the vehicle for life.
Where to find the VIN
- At the base of the windscreen on the driver’s side (visible from outside).
- On the driver’s-side door jamb or door frame sticker.
- In the engine bay or on the firewall.
- On the registration papers and, usually, the roadworthy/safety certificate.
What a VIN check tells you
Run against the national Personal Property Securities Register (PPSR), a VIN check reports:
- Finance owing (encumbrance) — if a lender has security over the car, that debt can follow the vehicle, not the seller.
- Written-off status — whether it’s recorded as a statutory or repairable write-off.
- Stolen status — whether it’s currently reported stolen to police.
- Registration and identification details to confirm the car matches its paperwork.
A PPSR certificate is the authoritative source for finance, write-off and stolen data. It’s a paid government register (a few dollars per search) at ppsr.gov.au — see our full PPSR check guide for exactly how to read a certificate.
VIN check vs rego check vs history check
| Check | What it uses | What it shows | Cost |
|---|---|---|---|
| Free rego check | Plate or VIN, per state | Registration status, expiry, sometimes written-off flag | Free (state road authority) |
| VIN / PPSR check | VIN | Finance owing, write-off, stolen, ID details | Paid (PPSR) |
| Full car history check | VIN + data sources | PPSR data plus odometer, past listings and more | Paid |
For the complete picture, combine a free state rego check with a PPSR search — that’s what our car history check hub walks you through, state by state.
How to run a VIN check — step by step
- Get the 17-character VIN from the car (windscreen or door jamb) and confirm it matches the rego papers.
- Run a free rego check with the relevant state road authority to confirm registration and look for a written-off flag.
- Buy a PPSR certificate at ppsr.gov.au using the VIN to check finance owing, write-off and stolen records.
- Keep the certificate — the search time and date can matter if a dispute arises later.
- Line the VIN check up with a physical pre-purchase inspection before you pay.
Red flags a VIN check can surface
A mismatch between the VIN on the car and the papers, a finance interest still registered, a repairable write-off the seller didn’t mention, or a stolen record are all reasons to walk away — or at least renegotiate with full information. Also worth checking: whether the car is a recorded write-off.
VIN check FAQs
Is a VIN check free in Australia?
Free state rego checks confirm registration and sometimes a written-off flag. To see finance owing, stolen and write-off records you need a PPSR certificate, which is a small paid government fee.
What’s the difference between a VIN check and a PPSR check?
The VIN is the number you search with; PPSR is the register you search. A “VIN check” run against PPSR returns finance, write-off and stolen data.
Can I check a VIN with just the number plate?
Free state rego lookups often accept a plate, but a PPSR search needs the VIN. Always confirm the VIN matches the plate and papers.
Does a VIN check show odometer rollback?
Not on its own. A PPSR certificate doesn’t guarantee odometer accuracy — a fuller car history check and a physical inspection help spot tampering.
