The Australian Standard for Person and provider identification in healthcare (AS 4846:2014) outlines the following principles of identifiers in healthcare:

Principle A: Identifiers shall be unique to a purpose and often to a person or organisation, although family group identifiers exist and are unique to the family.

Principle B: Identifiers shall not be recycled or reused.

Principle C: Each person or organisation should have a single active identifier from a given issuer for a specific usage at any given point in time.

The combination of 3 identifier data elements—Identifier designation, Identifier—identifier issuer, text X[X(199)] and Identifier—identifier usage, code NNN—uniquely identify an entity for a specific purpose, and is known as a globally unique identifier.
