Why can’t I change my mobile phone number myself?

Mobile phone numbers are used to provide extra security for your account. Usually they’re registered for two-factor authentication, which provides secure codes to authorise some transactions or requests. Because of the level of security mobile numbers provide, you are unable to update this yourself.

To update your mobile phone number with us, please click Messages within Internet Banking to let us know your mobile phone number, call us on 138 001 or visit your closest branch.
