Ireland IBAN format
A Ireland IBAN is 22 characters long: the IE country code, 2 check digits, and a 18-character BBAN (4 letters + 6 digits + 8 digits). Here is how a generated test IBAN breaks down:
| Part | Example | Format |
|---|---|---|
| Country code | IE | 2 letters (ISO 3166) |
| Check digits | 71 | 2 digits: mod-97 checksum |
| Bank code | SOUZ | 4 letters |
| Branch code | 432048 | 6 digits |
| Account number | 14871789 | 8 digits |

About Ireland IBANs
- Ireland uses the same 22-character layout as the UK: 4-letter bank code + 6-digit sort code + 8-digit account number.
- Irish sort codes identify branches within Ireland's clearing system, parallel to but separate from the UK's.
- Ireland is in SEPA; euro transfers use IBAN only, no BIC needed.
Use test Ireland IBANs for
- Testing payment forms that accept Ireland bank details.
- QA fixtures and demo data with the correct 22-character structure.
- Validating your own mod-97 implementation against known-correct outputs.
Country-specific testing notes
The bank-letter field, sort-code digits and account component are separate parts. Preserve the bank letters and do not insert display separators into the national fields.
Test more than the happy path
Generate with seed country-regression-v1, preserve the selected country and quantity, then run again to reproduce the same rows. Include an invalid-checksum input and a shorter input in your form tests. The versioned fixture pack supplies expected results for the implemented format checks.
Interpret the result correctly
Our checks cover the registered length, character pattern and international check digits. They do not certify domestic checksums, reserved-value rules, active bank codes, account existence or recipient ownership. Use bank-issued details for payments and your provider’s documented sandbox values for integration tests.
