If you know your Provider numbers, please enter them here. Click below to see our guide on how to obtain your provider numbers. Do not enter previously OpBill registered provider numbers UNLESS there is a change of details ie banking, address etc. In which case you will need to also select ‘change of details’ and add all registered provider numbers. Entering a provider number here that does not require any changes will DELAY the registration of your account or potentially delay billing dates whilst the details are being updated.
