Switch your mobile phone number to Optus

In this article we'll go through what you need to do to transfer your mobile phone number to Optus from another carrier.

You'll need to make sure of the following:

  • You must be the account holder with your current service provider
  • Your number is currently active
  • You have access to the current mobile number
  • Check with your current provider about early termination fees

Note. Optus is not liable for any fees or charges incurred by your previous service provider.

When you sign up to an Optus mobile service, we'll ask you if you'd like to keep your mobile number.


To protect our customers from unauthorised transfers/ports, an additional identity verification process is in place.


You'll receive a once-off verification code via SMS to the mobile number you wish to transfer over. You'll then need to provide the code back to us before we go ahead with the transfer.


If you're signing up online, you'll need to provide the code when prompted.


Note. Once your number has switched over to Optus, your current service will be disconnected.

It can take 15 mins to 4 hours for the transfer to be complete.

Transfers to Optus are completed between the following timeframes:

    • Monday -Friday: 8am-8pm AEST
    • Saturdays: 10am-6pm AEST

Note. Except on national public holidays.

For requests outside of these hours, your service will remain active with your existing provider until the next day.

If you suspect that your mobile number has been fraudulently transferred/ported, you should immediately report the activity to:
