AU Health Care Card Number

This identifier profile defines Health Care Card number in an Australian context (see Services Australia for further information).

This definition supports sending the Centrelink Customer Reference Number (CRN) (also referred to as unique identifier number (UIN) in the Centrelink Confirmation eServices (CCeS)) as displayed on the individual's Health Care Card (see Services Australia for further information). An individual's CRN is present as the primary identifier on different concession cards and is used to confirm concessions by most government agencies and utility providers.

A Health Care Card is a concession card assigned by Services Australia to benefit recipients, low income earners and selected other groups (e.g. foster children) to assist with certain health costs, by allowing access to specific services at a concessional rate.
