Director Identification Number

The Australian Government has announced the introduction of a new mandatory Director Identification Number (DIN/director ID) as part of the Modernising Business Registry (MBR) Program. The roll-out will start from November 2021.

The DIN will provide accountability and traceability of a director’s relationships over time, across all companies and will provide information on a director’s involvement in what may be repeated unlawful activity, including illegal phoenix activity.

Key points

  • A DIN will be a legal requirement for all new and existing directors to hold
  • A DIN is a unique 15 digit numerical identifier that an existing or intending director will apply for once and keep forever
  • Only one DIN will be issued to each individual, once their identity has been verified
  • The issued DIN will remain the same even if that person stops being a company director, changes their name or moves overseas
  • This will apply to directors of a company, body corporate or corporation.
  • It is not applicable to secretary’s
  • Alternative directors are also required to apply for a DIN
  • Directors must apply for their direct ID themselves. No one can apply on their behalf, including registered agents and accountants

How to apply for a DIN

Directors will need to apply online at, from November 2021 and will require a MyGovID (an app you download on your smart device, different from MyGov) to complete the application process.

When will a director need to apply for a DIN?

Transitional arrangements will allow directors to become familiar with the new requirement. When you need to have a director ID will depend on when you were appointed as a director.
