Germany test IBAN numbers

Ten checksum-valid Germany test IBANs with their domestic bank code and account number, ready for a payment form, fixture or unit test, plus invalid DE cases that a correct validator must reject.

Synthetic only: the bank code may belong to a real Germany bank, but each account number is random. Never use these values for payments or to represent a real account.

Invalid DE IBANs for negative tests

Each value is derived from the first valid IBAN above and re-checked, so the expected result is exact.

CaseInputExpected validator result
Wrong check digits DE04574601175581326306 Reject: MOD-97 checksum fails
Transposed BBAN digits DE03754601175581326306 Reject: MOD-97 checksum fails
One character too short DE0357460117558132630 Reject: length does not match the country format
Wrong country prefix FR03574601175581326306 Reject: length or checksum fails for the other country

Germany IBAN format

DE + 2 check digits + 8 digits + 10 digits = 22 characters. Validate the length and character classes first, then the MOD-97 checksum: move the first four characters to the end, convert letters to numbers (A=10 … Z=35) and the remainder modulo 97 must be 1.

Need rows for the same bank, city or BIC your integration talks to? The generator can target them, keep a stable seed and export 1,000 rows at a time.

curl -X POST https://ibangen.com/api/v1/generate \
  -H "X-API-Key: $IBANGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"country": "Germany", "quantity": 100}'

Test against real bank structures, not just checksums

Free: 10 DE rows at a time. Pro adds bank targeting, 1,000-row batches, CSV/JSON exports and the API; Business adds exact BIC and branch targeting.

Questions

Are these Germany test IBANs real bank accounts?

No. They are synthetic DE IBANs with a correct national format and MOD-97 checksum. The bank code can match a real institution, but the account number is random and must never be used for payments.

How long is a Germany IBAN?

A Germany IBAN has 22 characters: the country code DE, two check digits and a 18-character BBAN (8 digits, 10 digits).

Can I get more Germany test IBANs for a specific bank or city?

Yes. The Germany generator creates up to 10 rows free. Paid plans add bank, city and exact BIC targeting, 1,000-row batches, CSV/JSON exports and the same data through the API.
