Individual Healthcare Identifiers

A number that identifies you for health care purposes.

An Individual Healthcare Identifier (IHI) is a unique number used to identify an individual for health care purposes.

It helps ensure health professionals are confident that the right information is associated with the right individual at the point of care.

You already have an IHI if any of the following apply:

  • you have a Medicare card
  • you have a DVA card
  • you’re enrolled in Medicare.

If you’re not eligible for Medicare or a DVA benefit, find out how to get an IHI.

If you’re not eligible for Medicare and already have an IHI, call us on the Healthcare Identifiers Service if you want to change your personal details.

You can use your IHI to get proof of your COVID-19 vaccinations.
