ASIC has told me that my company can't do certain things without a Corporate Key. What is a Corporate Key?
The corporate key is an 8-digit number uniquely associated with a company's ACN. In many respects it is similar to the PIN on a bank account and is used to keep your company information secure. Every company needs only one corporate key.
Once you have a corporate key you can register to view your company records and lodge documents for your company online. Once you have online access you will no longer need to use your corporate key to lodge online.
The corporate key is sent by ASIC to the registered office within a day or two of registration.
If your corporate key has been lost, you can apply for a new one with ASIC.
