Frequently Asked Questions

How does IBAN validation work?

The initial 4 characters are moved to the end, letters are converted to digits (A=10 through Z=35), and the resulting number is evaluated modulo 97. If remainder equals 1, the IBAN is mathematically valid.

What is the difference between SWIFT and BIC codes?

There is no difference; BIC (Bank Identifier Code) and SWIFT code refer to the exact same ISO 9362 standard. It is an 8 or 11 character code identifying financial institutions globally.

Does IBAN validation show account balance or owner name?

No. IBAN validation is a purely mathematical syntax and check digit verification (MOD 97-10). It cannot access private bank records, balances, or individual account holder identities.
