How to check your own number on Telstra
To check your own Telstra number, open your phone dialer and dial #150# — it's free and your number shows on screen (or arrives by text). If that doesn't work, iPhone: Settings → Phone → My Number. Android: Settings → About phone → SIM status. Or the My Telstra app. Or detect it automatically.
On iPhone, tap‑to‑dial may not run USSD codes automatically — copy the code and dial it manually if it doesn't open the keypad.
Step by step
- Open the phone dialer. Open the dialer/keypad app on your phone.
- Enter the code. Type #150# exactly as shown.
- Press call. Press the call button — it is free.
- Read your number. Your phone number appears on screen (or arrives by text).
What you'll see: Your Telstra account details, including your mobile number, appear on screen.
If that doesn't work
iPhone: Settings → Phone → My Number. Android: Settings → About phone → SIM status. Or the My Telstra app.
#150# shows account info including your number on most Telstra services — confirm if your plan differs.
What your Australia number looks like
A Australia mobile number is mobiles start 04 (10 digits national), written +61 4XX XXX XXX — for example 0412 345 678 / +61 412 345 678. If what you see doesn't match that, you may be reading a different field (such as the ICCID/SIM serial) rather than your number — re‑check with the method above.
