PayID is a service that allows you to use a unique identifier (such as your mobile number) and link it to one of your eligible accounts to receive NPP real time payments. Your PayID can only be registered to one account at a time. For example, if you register your PayID to your personal transaction account then any payments made to your PayID will be paid into that account.
After you create a PayID you can simply tell payers to make payments to your PayID instead of having to remember your BSB and account number.
It’s optional to set up a PayID so you can bank as normal without one.
