Tools 5 found in our last check
validate_ibansCheck IBANs: country format, length, MOD-97 check digits and, where the country has one, the national check digit of the account number. Up to 10 IBANs per call without an API key. A valid IBAN is well-formed; it does not prove the account exists.
generate_test_ibansGenerate synthetic, checksum-valid test IBANs for a country (119 countries, real bank codes). Without an API key: up to 10 a day per user. Name a bank to get IBANs of that bank: free samples without a key, any number with a paid key. Test data only, never for payments.
bank_test_ibansA bank's BIC, domestic bank code and free sample test IBANs that carry the bank's real code, plus the bank page and the Bank Target Pack link for up to 250 IBANs of that bank.
iban_formatA country's IBAN length, structure (bank code, branch, account and check digit positions), SEPA membership, currency, national check digit, regex and one example test IBAN.
calculate_ibanBuild an IBAN from national bank details (bank code, branch code, account number). Adds the IBAN check digits and, where the country has them, the national check digits such as the French RIB key or the Italian CIN. Use iban_format to see which parts a country needs.
