How to Read a Spain IBAN
Every IBAN starts the same way: the first two letters are the country code (ES) and the next two digits are the mod-97 check digits, computed over the entire number. What follows is Spain's domestic account format: 4n bank, 4n branch, 2n check, 10n account.
For an international transfer to Spain you will typically need this IBAN plus the bank's SWIFT/BIC code, which you can verify with our SWIFT Code Checker.
