What is a Director Identification Number?

A Director Identification Number is a unique 15-digit number that is being introduced to reduce director identification fraud.

Once you have a DIN, you will keep that number forever and use it for all company directorships.

    2. PAYG payment summary
    3. Dividends statement
    4. Centrelink payment summary
    5. Bank account details
    6. Superannuation account details
