Frequently Asked Questions
How is IBAN validity checked?
The validator applies the official mod-97 checksum process after rearranging and expanding the IBAN string.
Can I validate multiple IBANs at once?
Yes. Paste one IBAN per line and each line is checked independently.
Does valid IBAN mean account is active?
No. Validity confirms format and checksum only, not whether the bank account is currently active.
