What is my IBAN?
IBAN
IBAN stands for International Bank Account Number. It combines your Bank Account Number and a new code so that your bank account can be used throughout the EU.
An example of an IBAN: IE99AIBK90000012345678
| Country Code | Check Digits | Bank Code (in this case AIB) | Sort Code | Account Number |
|---|---|---|---|---|
| IE | 99 | AIBK | 900000 | 12345678 |
The branch sort code and your account number are part of your IBAN. Irish IBANs will always contain 22 characters and be in the above format. The check digits are simply two digits that enable your IBAN to be validated.
