Legal Update Alert: Director Identification Numbers To Become Mandatory By ASIC

From 1 July 2027, Director Identification Numbers (DIN) will be integrated into the Australian Securities and Investments Commission (ASIC) Companies Register. This is part of a wider overhaul of Australia’s business registry framework introduced under the Treasury Laws Amendment (Business Registries Stabilisation and Uplift) Act 2026, which passed both Houses of Parliament and received Royal Assent on 30 June 2026.

What is a DIN?

A DIN is a unique 15-digit identifier given to any person who is, or intends to be, the director of a registered Australian company, a corporate trustee or a director of a registered foreign company that is undertaking business in Australia. Applying for a DIN is free, and is done through the Australian Business Registry Services (ABRS).

How is ASIC Incorporating DINs?

Schedule 1 of the Act requires companies to include a DIN in their reports to ASIC. These reports include the mandatory annual review and any time that a company director’s details or appointments are updated.

It is expected that directors will obtain their DIN before appointment. From 1 July 2027, a director must give their DIN to the company within seven days of appointment, and the company is then responsible for reporting it to ASIC. A limited grace period applies where a director does not yet hold a DIN: the director has seven days from receiving the number, and the company then has 14 days to lodge it with ASIC.

ASIC is given the power to disqualify an individual from managing corporations for up to three years if they fail to apply for a DIN when directed, and can also deregister companies for providing misleading information. Companies that are not registered with ASIC are not classified as a legal entity, and therefore cannot operate, own property, enter contracts or sue. These changes are a part of ASIC’s shift from passive compliance to active enforcement of director identity obligations.

Why Are These Changes Being Enacted?

DINs becoming a prerequisite for ASIC reporting can be seen as an inconvenience, particularly for foreign directors who may have to wait longer for identity verification to be issued a DIN. There are, however, practical reasons why ASIC is undergoing these changes.

DINs are the backbone of ASIC’s push towards data integrity. Historically, ASIC has relied on unverified, self-reported details. Making DINs mandatory, however, makes their records more reliable. This is done in two ways:

• Identity Verification: directors must verify their identity through MyID before a DIN is issued, ensuring that people running Australian companies are who they say they are.
• Tracing Corporate History: Because a DIN remains attached to a director for life, ASIC is able to track their directorships across multiple companies. This is done to crack down on illegal phoenix activity, wherein a director deliberately liquidates and abandons an established indebted company and then transfers those business assets to a new entity, thereby continuing operations debt-free.

Conclusion

Changes to DIN requirements reflect ASIC’s new dedication to data integrity; replacing an old system where information is self-reported to one where director identity is verified, standardised and enforced. To prepare for these changes, directors should apply for a DIN if they haven’t already, and account for time-sensitive director appointments where acquiring a DIN on time may be challenging.
