Support/FAQs / What is the Pre-port verification process?

Pre-port verification is an additional identification process used to verify your ownership of your existing mobile phone number being transferred to Cmobile during the SIM activation process. It is to protect you from unauthorised transfers of mobile numbers as a requirement of the “Telecommunications (Mobile Number Pre-porting Additional Identity Verification) Industry Standard 2020” published by the Australian Communications and Media Authority.

When you submit your SIM activation to Cmobile and request your existing number to be transferred, you will receive a 6 digit code sent to your mobile phone via SMS. You need to enter this code in the Pre-port verification window as soon as you receive it to ensure you are the owner of the mobile phone number. If you have any issues, please contact us on 1300 545 000 or email

If you believe your phone number has been ported fraudulently to another operator you should report this to:
(a) the Australian Federal Police or the relevant State or Territory Police, and
(b) government services, such as Scamwatch and IDCARE that support customers whose mobile service number is the subject of an unauthorised port.
