IBAN Structure Ireland

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Ireland's IBAN has 22 characters in the format IEkk BBBB SSSS SSCC CCCC CC. It begins with IE, two check digits, a 4-letter bank code (e.g. AIBK for AIB, BOFI for Bank of Ireland), the traditional 6-digit sort code and the 8-digit account number. Ireland is a euro member and fully SEPA-integrated, so transfers need only the IBAN. Unlike the United Kingdom — which uses a similar sort-code layout — Ireland exposes the sort code directly as part of the IBAN. A euro transfer costs the same as a domestic payment.
