Structure of a Spanish IBAN

How does IBAN validation for Spain work?

Our IBAN Validator checks the Spanish IBAN according to internationally defined ISO standards:

• Check of the correct IBAN length (24 characters)
• Validation of the country code “ES”
• Calculation of the check digits using the Modulo-97 method
• Analysis of the structural composition

The check only confirms the formal validity of the IBAN. Verification of the account holder or account status is technically not possible.
