How to Check a Car by Rego Number in Australia

Rego Number Lookups in Australia

In Australia, a vehicle's registration number ("rego number") is the most visible identifier you have before contacting a seller. Every state transport authority offers some form of free online registration check, making Australia one of the easier countries for preliminary vehicle verification. But a rego check alone is not enough — you need a PPSR check and ideally a full vehicle history report to be safe.

Essential reading: Always run a VIN check and a PPSR check before buying any used car.

What Free Rego Checks Show

Each state's transport authority offers a free online registration check. You can typically find:

• Registration status — current, expired, or cancelled
• Registration expiry date
• Vehicle details — make, model, year, body type, colour
• CTP insurance status (in most states)
• Weight and engine details
• Whether the vehicle has been reported stolen (some states)

State-by-State Tools

New South Wales (Service NSW): Free rego check showing rego status, expiry, vehicle details, CTP insurer, and defect notices.

Victoria (VicRoads): Free registration check showing rego status, expiry, vehicle details, and roadworthy certificate status.

Queensland (TMR): Free registration check showing rego status, expiry, vehicle details, CTP status, and safety certificate status.

South Australia, Western Australia, Tasmania, ACT, NT: Each has an online registration check with similar basic information through their transport authority.

What Rego Checks Do NOT Show

Free rego checks have significant limitations:

• No financial encumbrance data — whether money is owed on the vehicle
• No accident history — whether the car has been in a crash
• No write-off status (some states show this, but not all)
• No odometer history — whether the mileage has been tampered with
• No ownership history — how many owners the car has had
• No owner details — personal information is not accessible

This is why the PPSR check and a vehicle history report are essential complements.

The PPSR: The Check You Cannot Skip

As detailed in our encumbrance guide, the PPSR at ppsr.gov.au shows money owing (if the car is used as loan security), stolen vehicle records, and write-off status (statutory or repairable). The PPSR uses the VIN for searching, not the rego number. So you will need the VIN from the seller or from the rego check results (some state checks display the VIN).

Understanding Australian Rego Numbers

Australian plates vary by state — each has its own format, colours, and design. The state of registration is immediately identifiable.

Key fact: In most Australian states, registration plates stay with the vehicle when it is sold. This is different from countries like Canada where plates belong to the owner. This means a plate lookup is more reliable for tracking a specific vehicle, and the plate history is tied to the car's history.

Why VIN Is More Reliable

A rego number tells you about the vehicle's current registration in one state. The VIN is permanent and national — it tracks the car through every state, every owner, and every event.

The rego check is your first line of defence — quick and free. But the VIN check and PPSR search are your real protection against buying a car with hidden problems.

Step-by-Step: Complete Checking Process

Step 1. Record the Rego Number

Note the full plate number and the state. A photo from the listing or in person is ideal.

Step 2. Run the Free Rego Check

Use your state's transport authority website. Verify the car is currently registered, check the details match what the seller described (make, model, year, colour), and note the rego expiry date.

Step 3. Get the VIN

Either from the rego check results (if displayed) or ask the seller directly. You need the VIN for the next steps.

Step 4. Run a PPSR Check

Go to ppsr.gov.au, search by VIN. Confirm no money is owing, confirm the car is not stolen, and check for write-off history.

Step 5. Consider a Vehicle History Report

Commercial providers offer comprehensive reports combining PPSR data, registration history, odometer records, and accident/damage information.

Step 6. Physical Inspection

Inspect the car in person. Verify VIN on the car matches documents and reports. Check for signs of accident repair. Look for discrepancies between the car and the rego check (colour, body type). See our inspection guide for the full checklist.

Red Flags

• Rego check shows different details than the listing (different colour, model, or year)
• Registration expired — the car cannot be legally driven; re-registration may require a roadworthy
• Defect notice on the vehicle — it may need repairs before it can be driven
• VIN on the car does not match the rego papers — possible stolen vehicle or VIN swap
• Seller does not know the rego number — unusual and suspicious
• Interstate plates on a car sold locally — may indicate recent move or possible history concealment

Privacy in Australia

Australian privacy law (Privacy Act) protects personal information. You cannot obtain the registered owner's name or address from a rego number through public services. Rego checks show vehicle information only. Only law enforcement and authorized parties can access personal registration data.
