Director Identification Numbers (DINs): What You Need to Know

Stay Compliant. Stay Informed.

A Director Identification Number (DIN) is a unique, permanent identifier assigned to individuals who are directors (or intend to become directors) of a company registered under Australian law. Introduced as part of the Modernising Business Registers (MBR) program, DINs are administered by the Australian Business Registry Services (ABRS) and are a legal requirement under the Corporations Act 2001.

The purpose of the DIN system is to:

  • Improve transparency and accountability in corporate governance

  • Prevent the use of false or fraudulent director identities

  • Deter and track illegal phoenix activity (where businesses are deliberately liquidated to avoid paying debts)

Once issued, your DIN remains with you for life, even if you change companies, roles, or cease being a director.

Who Needs a DIN?

A DIN is mandatory for anyone who is a director (or acting alternate director) of:

  • Australian companies registered under the Corporations Act 2001

  • Foreign companies registered to operate in Australia

  • Registered Australian bodies, such as incorporated associations

  • Charities and not-for-profits that are registered with ASIC or the ACNC and have corporate structures

Note: DIN requirements currently apply only to formally appointed directors — not to shadow or de facto directors, although these roles still carry legal obligations.

When Must You Apply?

The deadline to apply depends on when you were appointed as a director:

 

Date of Appointment Apply by
Before 31 October 2021 By 30 November 2022 (past deadline)
Between 1 Nov 2021 – now Before appointment (mandatory)

If you are planning to become a director, you must apply for your DIN before your appointment is registered.

For the latest rules, visit the official guidance at the ABRS website.

How to Apply for a DIN

Applying for a DIN is a secure and straightforward online process, but must be done personally by the individual — agents, accountants, or lawyers cannot apply on your behalf.

Steps to Apply:

  1. Set up myGovID – You’ll need a Standard or Strong identity strength myGovID (not the same as your myGov account).
    Get started with myGovID

  2. Visit the ABRS Online Portal – Login using your myGovID.
    Apply here via ABRS

  3. Verify your identity – You'll be asked to confirm personal details, such as your tax file number (TFN), address, and other ATO-linked documents.

  4. Receive your DIN – Once verified, your DIN will be issued instantly and sent to you for safekeeping.

Why It's Important

Failing to comply with DIN requirements can result in civil or criminal penalties, including:

  • Fines of up to $13,320 (civil)

  • Criminal penalties of up to $26,640 or 12 months’ imprisonment for serious offences

Keeping your DIN secure and ensuring your details remain current with ABRS is critical for ongoing compliance.
