Check registration

Penalties apply for driving an unregistered vehicle or operating an unregistered boat. If you're not sure that a vehicle or boat is registered, it's best to check.

Online services are temporarily unavailable outside Australia.

If you need assistance while overseas contact Service SA.

To check a vehicle (including a car, caravan, motorcycle or trailer), you'll need the plate number.

To check a boat, you'll need the boat registration number.

Enter the plate number or boat registration number without any spaces or dashes.

Other details you can check

Other information returned from this check may include:

  • make
  • body or hull type
  • compulsory third party (CTP) insurer (vehicles only)
  • heavy vehicle details (gross vehicle/combination/trailer mass).

Expiry and renewal

Registration is valid until midnight on the expiry date - eg if the registration is due to expire on 26 June, the vehicle can be driven up until midnight on 26 June.

You can check and manage your registration with a mySAGOV account. Create an account if you don't already have one.


You can renew your vehicle registration online even if it has expired.

You can also sign up for digital renewal notices in your mySAGOV account to receive electronic notifications when your registration is due to expire.


You can renew your boat registration online. If it has expired, your registration will automatically update from the date of payment (no higher administration fee applies).
