Boat Code identification system

Boat registration labels not required from 1 September 2023. Visit for more information.

Boat Code is a unique identification system for registered boats and other vessels.

Two identical Hull Identification Number (HIN) plates are affixed to the vessel's hull. One plate must be clearly visible on the starboard (right) side of the transom, with the second hidden elsewhere on the vessel.

When do you need Boat Code?

Boat Code is compulsory when:

  • registering a boat in South Australia for the first time
  • applying for change of ownership of a vessel that does not have a HIN, or has a HIN that is not yet recorded in South Australia.

If your vessel has a Boat Code from interstate but you cannot produce the Boat Code certificate, you will need to have the HIN validated by a Boat Code agent.

All registered owners of recreational vessels who wish to take advantage of the security benefits that Boat Code provides are encouraged to apply for voluntary Boat Code.

What are the benefits of Boat Code?

Boat Code provides security for owners by deterring theft. It can assist with tracking and recovering your boat if it is stolen.


A vessel registered in the same name on the Australian Shipping Register is exempt from complying with the Boat Code system.

The Australian Shipping Register is maintained by the Australian Maritime Safety Authority in Canberra.

If the vessel is to be exempt then proof of the Australian Shipping Registration is to be presented with the application for recreational registration.
