Bank of Ireland’s BIC is BOFIIE2D, so its IBANs carry BOFI after IE and the check digits, followed by your six-digit NSC and eight-digit account number.

This page is for accounts in the Republic of Ireland. Bank of Ireland accounts in Northern Ireland and Great Britain use the BIC BOFIGB2B and have GB IBANs.

Holyheld is not affiliated with Bank of Ireland. Your bank’s app or statement shows your IBAN too; if it differs from the one built here, use your bank’s.
