Healthcare Identifiers Service (HI Service)

A healthcare identifier is a unique number that has been be assigned to individuals, and to healthcare providers and organisations that provide health services.

The identifiers are assigned and administered through the HI Service which was established to undertake this task. The HI Service is operated by the Chief Executive Medicare.

A key aim of healthcare identifiers is to ensure that individuals and providers can have confidence that the right health information is associated with the right individual at the point of care.

For further information on the HI Service and healthcare identifiers please refer to the Frequently Asked Questions on the HI Service or phone the Department of Human Services on 1300 361 457.

Healthcare identifiers are an initiative of the Council of Australian Governments (COAG) that was developed through the National E-Health Transition Authority (NEHTA).

For more information, view NEHTA's work program.


The implementation of healthcare identifiers is supported by a strong and effective legislative framework that includes governance arrangements, permitted uses and privacy safeguards.
