Corporate key

This page relates to the corporate key, which is used to update company details.

To learn more about the ASIC key, which is used to update business name and SMSF auditor details, see ASIC key.

What is a corporate key?

A corporate key is an 8-digit number uniquely associated with a company’s ACN. Your company needs only one corporate key.

In many respects a corporate key is similar to the PIN for a bank account and is used to keep your company information secure.

Where can I find my corporate key?

A corporate key is issued when a company is registered.

We will send a letter containing a company's corporate key to its registered office within two days of registration with us. After that, the corporate key will appear in the top right corner of the annual company statement.

How do I use my corporate key?


After you have a corporate key, you can register to view your company records, lodge forms for your company and receive annual statements online. After registering, you will no longer need to quote your corporate key to lodge forms online.

Paper forms

When lodging paper versions of the following forms, you must enter the corporate key in the space provided on the form.

  • Form 362 Notification of appointment or cessation of a registered agent by a company
  • Form 484 Change to company details
  • Form 486 Notification to nominate, change or cease a contact address for a company

If the correct corporate key is not entered on the form, we will contact you for this information. Therefore to ensure timely processing of any changes to your company details, you need to ensure that the correct corporate key is entered in the space allocated on the form.

Who can request a new corporate key?

A company officeholder, registered agent, liquidator or administrator can request a new corporate key. The corporate key will only be sent to the registered office of your company, to avoid it being sent to an unauthorised recipient. If you are unable to receive the company’s corporate key at the registered office address, it may be possible to send the corporate key to a contact address or an officeholder’s residential address recorded on our database. To ask for your corporate key to be sent to an address other than the registered office, please contact us by phone on 1300 300 630 or online.

How do I get a new corporate key?

You can request the cancellation of your company's existing corporate key and ask for a new corporate key to be issued online.

You might need a new corporate key if you forget the number or feel that the security of the corporate key has been compromised (e.g. an unauthorised person gains access to the number).

How can a corporate key be cancelled?

A corporate key is fixed for the life of the company unless one of the following occurs:

  • a Form 361 Notification of a registered agent ceasing to act for a company or Form 362 appointing or ceasing a registered agent is lodged;
  • a new corporate key is requested by an authorised person; and
  • in some instances if correspondence sent by us to the company is returned to us as ‘return to sender’ mail.

Registered agents and corporate keys

A registered agent will receive a company’s corporate key if:

  • a paper Form 362 is lodged, appointing the agent to the company, or
  • if the registered agent’s address is the company’s registered office address.

Where a Form 362A is lodged by paper, the existing corporate key is cancelled (if not already done so) and a new corporate key is generated and sent to the new registered agent electronically through their EDGE or Easylodge inbox, or alternatively by paper if they do not have online access.

Registered agents are authorised by their clients to conduct all business with us on behalf of their clients including lodging all forms. In these circumstances companies do not need access to their corporate key. However, a corporate key is a client's property, and if they request it, the agent should give them the corporate key.

Registered agents have an obligation to keep clients’ corporate keys confidential.

Using your corporate key to register for online access

You can use your corporate key to apply for online access.

Once you have registered you will be able to:

Check and change company details You can check your company details online and change these details by lodging the appropriate forms online.
Receive your annual company statement online You will receive your annual company statement and invoice online, after the company review date. As an online user, you will receive an email alert when this occurs.
Receive other information from ASIC For example, you will receive confirmation that a paper form has been lodged that changes critical information about your company on our register. You may also receive a request to amend a recently lodged form to allow us to process it fully.

Officeholder's registration

You only need to register for online access once. If you are an officeholder for more than one company, you can link each company to your registration. You will then be able to use the same user name and password to check details for each company.

New officeholders registering for access will need to use the company’s corporate key. When you apply to register you will be asked to:

Agree to terms and conditions You must agree to any terms and conditions of use for our online services as set out in our Electronic Lodgement Protocol.
Create a user name and password

You will need to create your own individual user name and password. It must be unique to you (i.e. each officeholder of the company must have a different user name when they apply to register for online access).

If you are an officeholder for more than one company you will be able to use the same user name and password for each company. To do this you need to:

  • apply for online access to register your user name for the first company and
  • then use the 'Add ACN' menu option to add the second company to your user name. You will need to know the corporate key of each additional company you wish to add to your user name. The corporate key is provided on your annual company statement or you can apply for a new corporate key online if you do not have an annual company statement.
Create a security question and answer

Your question and answer will be used to verify your access if you forget your password. You should be the only person aware of your security question and answer.

We will not be able to reset your password over the telephone. You will need to register again if you have forgotten your user name, password and the answer to your security question.

Remember your corporate key after you register for online access

When you lodge forms online you don’t need to use the company’s corporate key, however, it is advisable to keep a record of it.

Even if you usually lodge forms online, you may occasionally need to lodge paper forms. You will need to quote your corporate key when lodging paper Forms 362, 484 or 486, whether you normally lodge forms online or not.
