Validate IBANs Instantly

An IBAN (International Bank Account Number) is a standardized international numbering system that identifies bank accounts across borders. It consists of up to 34 alphanumeric characters including a country code, check digits, and bank-specific information.

Why it matters: IBANs prevent transaction errors, speed up international transfers, and ensure compliance with global banking standards.

To validate an IBAN:

1. Enter your IBAN in our validation tool above
2. The system checks the format, length, and checksum
3. Receive instant results with bank details if valid

IBAN: Identifies the specific bank account (account number format)

SWIFT/BIC: Identifies the bank institution (bank identifier)

For international transfers, you typically need both:

• IBAN to specify the exact account
• SWIFT/BIC to identify the receiving bank

Our validator provides both when available for complete transaction details.
