The 30-second version
- Compare the VIN and registration number on the certificate directly against the numbers stamped on the car and shown on NaTIS documents.
- Check the issue date and confirm the certificate is still within its valid period for your specific transaction type.
- Accredited testing stations can generally confirm whether they issued a specific certificate — call and ask.
- A generic-looking certificate, a testing station you can't verify, or reluctance to let you check it are all warning signs.
- A genuine roadworthy certificate confirms the car passed on the day it was tested — it isn't a guarantee of ongoing condition.
A roadworthy certificate carries real weight in a used-car transaction — it's often required for change of ownership, and buyers reasonably treat it as a sign the car has been checked over. That trust is exactly why a forged, mismatched or out-of-date certificate is a real risk worth checking for, not a paranoid one.
The core check: does it actually match this car
The single most important verification is the simplest: does the VIN/chassis number and registration number on the certificate match the numbers stamped on the vehicle and shown on its NaTIS documents? A certificate is only valid for the specific vehicle it was issued for — a certificate for a different car, even the same make and model, is worthless for this one.
Checking the certificate itself
What to look for
- Issue date and validity — validity periods differ depending on the transaction type. Check the date isn't expired for your specific purpose.
- The testing station's details — name, accreditation number, and contact details should be printed clearly on a genuine certificate.
- Consistent, professional printing — smudged text, obvious font mismatches, or signs of alteration are worth questioning.
- A tester's signature and stamp — a certificate missing these, or with an unclear or generic stamp, deserves a closer look.
Verifying with the testing station directly
If you have any doubt, call the testing station named on the certificate and ask them to confirm they issued it, using the certificate number and vehicle details. Accredited testing stations can generally check this on request. This is a five-minute phone call that removes almost all uncertainty, and it's a reasonable thing to do before a private purchase — a legitimate seller shouldn't object to you confirming it.
Common mistakes
- Checking the certificate exists but never comparing its VIN against the car itself.
- Assuming a roadworthy certificate means the car is currently in good mechanical condition — it only confirms the state on the test date.
- Not checking the issue date against the validity period for your specific transaction.
- Skipping a five-minute confirmation call to the testing station when something feels off.
