Portugal test IBAN numbers

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

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

Invalid PT 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	PT51000776584247052901705	Reject: MOD-97 checksum fails
Transposed BBAN digits	PT50007076584247052901705	Reject: MOD-97 checksum fails

Portugal IBAN format

PT + 2 check digits + 4 digits + 4 digits + 11 digits + 2 digits = 25 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.

Test against real bank structures, not just checksums

Free: 10 PT 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 Portugal test IBANs real bank accounts?

No. They are synthetic PT 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 Portugal IBAN?

A Portugal IBAN has 25 characters: the country code PT, two check digits and a 21-character BBAN (4 digits, 4 digits, 11 digits, 2 digits).

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

Yes. The Portugal 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.
