Frequently Asked Questions
- How is an IBAN validated?
- An IBAN is validated mathematically using the modulus-97 (ISO 7064 MOD-97-10) check digit algorithm, ensuring the structure and checksum are correct before any money is routed.
- Is an IBAN the same as a SWIFT code?
- No. An IBAN identifies a specific individual bank account, whereas a SWIFT/BIC code identifies the bank and branch itself.
