Have you or someone with authority for the mobile number or email address already created the PayID at IMB or another Financial Institution? A mobile number or email address can only be used to create a PayID at one Financial Institution.
If this is not the case you should contact IMB on 133 462 (Monday - Friday 8am - 8pm or Saturday 9am - 4pm) and prove ownership of the PayID. Once this has been confirmed:
If the PayID is held by IMB we can close the PayID and you can create it; or
If the PayID is held by another Financial Institution we will contact them to resolve ownership of the PayID via the PayID Dispute Resolution Process. We will investigate the dispute on your behalf and resolve ownership of the PayID with the other Financial Institution.
