Director Identification Number (DIN)

Updated: Oct 16, 2022

A Bill was passed on the 12 June 2020 that requires all directors of Australian companies to have a director identification number (director ID).

You will need to apply for a DIN if you are a company director. This includes if you are director of your SMSF corporate trustee or family trust.

What is a director ID?

A director ID is a unique 15-digit identifier that a director will apply for once and will keep forever. A director can only have one director ID that they must use for all companies.

The purpose of introducing director IDs is to prevent the use of fictitious director identities, assist regulators trace directors’ relationships with companies and better identify directors involved in unlawful activity.

When you must apply for a director ID depends on the date you became a director.
