The ASIC maintains a unique identifier for each company, called the Corporate Key. This is an 8 digit number, that is associated with the ACN of the company. This identifier is used for security purposes. The ASIC has provided this as “a security feature to prevent unauthorised persons altering your company information”.
For more information, see http://asic.gov.au/online-services/online-keys/corporate-key/.
The Corporate Key is private information, which is only known to ASIC and the person who received the Company Statement. The Corporate Key is updated by ASIC each year for security reasons.
