What is IBAN?
IBAN (International Bank Account Number) is a standardized format for identifying bank accounts across borders. Used in 80+ countries for international and domestic transfers.
Why validate IBANs?
Validating IBANs before processing payments prevents failed transfers, returned payments, and delays. Always verify bank details before sending money.
How validation works
IBAN validation checks the country code, length, format, and uses the mod-97 checksum algorithm to verify the check digits are correct.
