After you have logged in, click ‘Need an ARN?’ and select 'Apply for aviation reference number (ARN)'.
Fill out your personal details. These include:
If you use Digital ID to log into myCASA, you will not need to provide any identification as we have already verified your identity. You should receive your ARN by email within a few minutes.
If you choose to log into myCASA with an email address and password, you will now need to submit a form of identification to verify your identity.
You will only need one type of identification. We can verify most identity documents online, including:
If you're using a foreign passport, you must be in Australia for us to verify it online.
We recommend you apply for your ARN when you arrive in Australia to make the process easier.
If your ID doesn’t automatically verify, check that you have entered the details exactly as they appear on the document. You can upload a certified copy of the document instead. However, this will mean it may take up to 5 business days to receive your ARN.
If you are a permanent resident of Australia, you can still submit a foreign passport if you are currently overseas.
After you have entered your details make sure to check they match your primary form of identity (including middle names) and submit. You should receive your new ARN by email within a few minutes after your ID automatically verifies.
If you have any problems applying for your ARN online, please call us on 131 757 during business hours to resolve them.
