Every Australian mobile number starts with 04 and has ten digits, under the numbering plan the ACMA administers. For a sign-up form or app you write it as +61 4XX XXX XXX: country code, then the number without its leading 0. If you only need it for one verification code, a one-time Australian number does that job.

X stands for any digit. Numbers can move between Australian carriers, so the first digits do not reveal the network.
Which services expect an Australian number
Most international apps accept numbers from many countries. An Australian number matters when a service only lets you sign up with a number from the country it operates in, or when the region of your account follows the number.
- Local apps for delivery, transport, classifieds or dating that check for +61.
- Region-specific sign-ups, where you want the account set up for Australia from the start.
- Keeping your own number private while you are in Australia, without buying a SIM for one code.
Which services have Australian numbers right now changes daily. The app lists them live, with a success rate per country.
Getting one from abroad
| Right for | Keep in mind | |
|---|---|---|
| A SIM or eSIM from an Australian carrier | Living, studying or working in Australia | The number you keep for every account |
| Free websites with public numbers | Trying something out | Everyone sees the code; most services refuse these numbers |
| A one-time Australian number | One verification code | Private to you for up to ten minutes, then closed |
Why free inboxes fail for verification: free SMS numbers.
