IBAN data sources and methodology
How IBANgen checks and generates IBANs, and where the bank code behind every country comes from. Bank names are only shown when a published list ties the code to the bank.
How an IBAN is checked
- Length and structure from the SWIFT IBAN registry (country code, BBAN length and character classes).
- IBAN check digits: ISO 13616 MOD-97.
- National account check where the country publishes a method (Bundesbank methods, French clé RIB, Italian CIN, Spanish control digits, UK modulus checks and others).
- Bank code lookup in the lists below, then the BIC; SEPA scheme membership (SCT, SCT Inst, SDD, Verification of Payee) from the EPC participant registers.
How test IBANs are generated
Every generated IBAN uses a real, allocated bank code from these lists and correct IBAN and national check digits. The account number is random, so the result is synthetic test data, never an account.

Questions
Where do the bank codes come from? From published bank-code lists: central banks and banking associations (Deutsche Bundesbank, Bank Al-Maghrib via ADII, BCEAO, BEAC, Banque Centrale de Tunisie, Central Bank of Egypt and others), the IBANAPI bank registry we license, GLEIF BIC-to-LEI files and the per-country lists ibangenerator.io publishes. The table names the lists used for each country.
How is an IBAN checked here? Four layers: length and BBAN structure from the SWIFT IBAN registry, the ISO 13616 MOD-97 check digits, the national account check method where a country publishes one, and a lookup of the bank code in the lists above. SEPA scheme membership comes from the EPC participant registers.
Are the generated IBANs real accounts? No. Generated IBANs use real, allocated bank codes and correct check digits, but the account numbers are random. They are for testing software and must never be used for payments.
What if a bank name is wrong? Write to [email protected] with the IBAN country and bank code; corrections go into the next data refresh.
Found a wrong bank name? Email [email protected] with the country and bank code.
