Individual registrations in the Australian Immunisation Register (AIR) 011-10040000

Individuals are registered on the AIR when:

• they enrol in Medicare
• they apply for an Individual Healthcare Identifier (IHI)
• vaccination information is received from vaccination providers

Individuals who are enrolled in Medicare are automatically included on the AIR. Their personal details are copied from their Medicare enrolment file and added to the AIR.

Part of the record received from Medicare includes a Personal Identification Number (PIN). This is a unique number used as a personal identifier by the AIR.

Changes to Medicare details, including end dates are updated overnight on the AIR.

Individuals who are not eligible, or not yet enrolled for Medicare can have records on the AIR. These individuals are allocated a Supplementary Identification Number (SIN).

Individuals are registered directly onto the AIR when vaccination information is received from a vaccination provider. This creates an AIR SIN record.

If an individual applies for an IHI, and they do not already have a record on the AIR, the system will automatically create an IHI SIN record for them.

Note: AIR Service Officers can identify SIN records created for IHI individuals by checking the AIR registration history. The message ‘IHI SIN CREATED’ will appear next to a system identifier.

If the individual is later enrolled in Medicare, their Medicare record is added to the AIR. The system tries to match records through data matching to:

• avoid duplicate records
• prevent inaccurate or incomplete vaccination history

If the personal details are different and the system is not able to identify a unique match, an individual may have multiple records. AIR Service Officers manually match or merge these records in the ‘daily resolution’ process.
