When to use IBAN Validator and Parser
Common situations where a quick IBAN inspection helps:
- Verify payment details before sending money
Paste an IBAN from an invoice or email and confirm the country format, checksum, and overall validity before you reuse it.
- Review copied IBANs without reformatting them by hand
The app removes spaces automatically, reformats the number, and shows the parsed core parts in a copyable report.
- Debug payment-form validation
Compare your app's validation results with a quick browser-side check when testing length and checksum behavior.
- Explain why an IBAN fails validation
See whether the country is supported and whether the checksum and length checks pass instead of getting a vague pass/fail result.
- Prepare support or QA notes
Copy the parsed report into internal documentation, tickets, or audit notes when reviewing payment details.
FAQ
- What does this app parse from an IBAN?
- It shows the formatted IBAN, country code, check digits, BBAN, expected length, actual length, and whether the country, checksum, and overall format pass validation.
- Does it identify the bank name or branch?
- No. It is a validator and basic parser only. It does not connect to banking directories or external registries.
- Do spaces or lowercase letters matter?
- No. The app removes spaces and normalizes letters to uppercase before it validates the IBAN.
- Why can the checksum pass while the overall result is still invalid?
- The checksum is only one part of validation. An unsupported country code or the wrong overall length still makes the IBAN invalid.
- Is my IBAN sent anywhere?
- No. The validation and parsing run entirely in your browser.
