A Ireland IBAN starts with the country code IE, followed by 2 check digits and the national account number (BBAN), for a total of 22 characters. ValidateFin verifies the mod-97 checksum (ISO 13616), the length and the format - entirely in your browser, no data sent to any server.
- •The IE BBAN embeds the 6-digit sort code used for domestic transfers, right after a 4-letter bank code.
- •The bank is identified by a 4-letter code (e.g. AIBK, BOFI) matching the first four characters of its BIC.
- •Ireland is a SEPA and eurozone country, so a IE IBAN is accepted for all euro SEPA payments even though sort codes remain in domestic use.
