The address code is issued once you have fully completed the account opening process.
If you have not received the address code, go back into the app to ensure that you have fully completed all the questions.
If you have fully completed the process and have still not received the address code or if your address has changed since you completed the process, you will need to drop into an AIB branch with a proof of current permanent address. You will also need to bring a valid form of photographic identification.
The address code is a one time sending and cannot be reissued.
