A Greece IBAN starts with the country code GR, followed by 2 check digits and the national account number (BBAN), for a total of 27 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 bank is identified by a 3-digit HEBIC (Hellenic Bank Identification Code) and the branch by a 4-digit code.
- •Greek IBANs carry an explicit 4-digit branch code after the bank code, identifying the specific outlet.
- •Greece is a SEPA and eurozone country, so a GR IBAN works for all standard euro credit transfers and direct debits.
