Bulk IBAN Validator

The Bulk IBAN Validator helps you verify multiple International Bank Account Numbers at once by simply pasting them line by line. Each IBAN is individually checked against the ISO 13616 standard, and validation results—including status, country code, and bank info—are displayed in a clear and organized table. Whether you're in finance, compliance, or managing international payments, this tool streamlines large-scale IBAN verification with ease and accuracy.

Enter one IBAN per line into the text area and click Validate IBANs. Each IBAN is checked independently and results are displayed in a structured table showing:

• IBAN
• Status (Valid / Invalid)
• Country code
• Bank information (if available)

This tool supports all countries that follow the ISO 13616 standard. Country-specific structure and length checks are enforced automatically.

The core validation follows the MOD97 algorithm:

$\text{IBAN} \bmod 97 = 1$ → If this condition is met, the IBAN is considered valid.

Each result row includes a copy-to-clipboard icon for user convenience.
