Ten checksum-valid Spain test IBANs with their domestic bank code and account number, ready for a payment form, fixture or unit test, plus invalid ES cases that a correct validator must reject.
Synthetic only: the bank code may belong to a real Spain bank, but each account number is random. Never use these values for payments or to represent a real account.

Each value is derived from the first valid IBAN above and re-checked, so the expected result is exact.
| Case | Input | Expected validator result | |
|---|---|---|---|
| Wrong check digits | ES2731662019252550543648 | Reject: MOD-97 checksum fails | |
| Transposed BBAN digits | ES2613662019252550543648 | Reject: MOD-97 checksum fails | |
| One character too short | ES263166201925255054364 | Reject: length does not match the country format | |
| Wrong country prefix | FR2631662019252550543648 | Reject: length or checksum fails for the other country | |
| Lowercase with spaces | es26 3166 2019 2525 5054 3648 | Accept after normalizing case and whitespace |
ES + 2 check digits + 4 digits + 4 digits + 1 digit + 1 digit + 10 digits = 24 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.

No. They are synthetic ES 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.
A Spain IBAN has 24 characters: the country code ES, two check digits and a 20-character BBAN (4 digits, 4 digits, 1 digit, 1 digit, 10 digits).
Yes. The Spain 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.
IBANgen provides synthetic QA data. It does not verify account ownership, balances, reachability or payment execution.
