About Germany IBANs
- Germany's BBAN splits into an 8-digit Bankleitzahl (bank sort code) and a 10-digit account number (Kontonummer).
- With 22 characters, the German IBAN is among the most-searched test formats in Europe: Germany has the EU's largest banking market.
- The Bankleitzahl is assigned by the Bundesbank; the first digit historically indicated the region.
Use test Germany IBANs for
- Testing payment forms that accept Germany bank details.
- QA fixtures and demo data with the correct 22-character structure.
- Validating your own mod-97 implementation against known-correct outputs.
Country-specific testing notes
The eight-digit Bankleitzahl and ten-digit account component must retain their full lengths. Bank-specific domestic conversion and account-check rules are outside this generator.
Test more than the happy path
Generate with seed country-regression-v1, preserve the selected country and quantity, then run again to reproduce the same rows. Include an invalid-checksum input and a shorter input in your form tests. The versioned fixture pack supplies expected results for the implemented format checks.
Interpret the result correctly
Our checks cover the registered length, character pattern and international check digits. They do not certify domestic checksums, reserved-value rules, active bank codes, account existence or recipient ownership. Use bank-issued details for payments and your provider’s documented sandbox values for integration tests.
