Frequently asked questions
An IBAN (International Bank Account Number) is a standardized format for identifying bank accounts across borders. It consists of a country code, two check digits, and the domestic account number. For Spain, IBANs have 24 characters.
IBAN validation uses the MOD-97 algorithm: the first four characters are moved to the end, letters are converted to numbers (A=10, B=11, etc.), and the resulting number must give a remainder of 1 when divided by 97.
No. This validator checks the mathematical correctness of the IBAN format and checksum. It confirms the number follows the standard structure but does not verify whether the account is open or active at a bank.
