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

Invalid IE IBANs for negative tests
Each value is derived from the first valid IBAN above and re-checked, so the expected result is exact.

Ireland IBAN format
IE + 2 check digits + 4 uppercase letters + 6 digits + 8 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.
No. They are synthetic IE 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 Ireland IBAN?
A Ireland IBAN has 22 characters: the country code IE, two check digits and a 18-character BBAN (4 uppercase letters, 6 digits, 8 digits).
Can I get more Ireland test IBANs for a specific bank or city?
Yes. The Ireland 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.
