Belgium test IBAN numbers

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

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

Invalid BE IBANs for negative tests

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	BE75945776733907	Reject: MOD-97 checksum fails
Transposed BBAN digits	BE74495776733907	Reject: MOD-97 checksum fails
One character too short	BE7494577673390	Reject: length does not match the country format
Wrong country prefix	FR74945776733907	Reject: length or checksum fails for the other country
Lowercase with spaces	be74 9457 7673 3907	Accept after normalizing case and whitespace

Belgium IBAN format

BE + 2 check digits + 3 digits + 7 digits + 2 digits = 16 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.

Questions

Are these Belgium test IBANs real bank accounts?

No. They are synthetic BE 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 Belgium IBAN?

A Belgium IBAN has 16 characters: the country code BE, two check digits and a 12-character BBAN (3 digits, 7 digits, 2 digits).

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

Yes. The Belgium 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.
