Aviation Reference Number [ARN]

« Back to Glossary Index

An Aviation Reference Number (ARN) is a numbering system used in Australia and is required for all aviation professionals (pilots, ATC staff and student pilots. The number is similar to a customer number and they need to quote their ARN number when filling in most application forms. The number on their license or training permit is usually the same as an aviation reference number.

Aviation numbers are issued for both organisations and individuals. The only pre-requisite is that the party must be a legal entity. This means that ARNs are not issued to business names, consortiums or partnerships.

Pilots, student pilots and flight crew need to have an ARN before you visit a designated aviation medical examiner (DAME) for a medical examination.
