  • ✓ Generate 1-100 IBANs at once
  • ✓ Support for 80+ countries
  • ✓ Custom bank/branch codes
  • ✓ Valid MOD-97 checksums
  • ✓ Export to CSV or JSON

Important Notice

⚠️ Test Data Only
Generated IBANs are for testing and development purposes only. They are mathematically valid but do not correspond to real bank accounts.
💡 Use Cases
Perfect for software testing, API development, form validation testing, educational demonstrations, and QA processes.
🚫 Not for Production
Never use generated IBANs for actual financial transactions. Always use real IBANs provided by legitimate financial institutions.

IBAN Generator for Testing & Development

Our IBAN generator creates mathematically valid IBANs that pass all format and checksum validations. These are perfect for testing payment systems, validating forms, or educational demonstrations.

How It Works

  1. Select a country from our list of 80+ supported countries
  2. Optionally specify bank and branch codes, or let the generator randomize them
  3. Choose how many IBANs to generate (1-100)
  4. Click generate to create valid IBANs with correct MOD-97 checksums
  5. Export results to CSV or JSON for use in your projects

Use Cases

🧪 Software Testing

Generate test data for payment processing systems, banking applications, and financial software QA.

🔧 API Development

Create sample IBANs for API documentation, integration testing, and development environments.

📚 Education

Demonstrate IBAN structure, validation algorithms, and international banking standards in training materials.

✅ Form Validation

Test form validation logic, input masks, and error handling for IBAN entry fields.

Features

  • Valid Checksums: All generated IBANs pass MOD-97 validation
  • Country-Specific: Follows exact format rules for each country
  • Bulk Generation: Create up to 100 IBANs at once
  • Custom Codes: Specify bank and branch codes or randomize
  • Export Options: Download as CSV or JSON for easy integration
  • Copy Functions: Copy individual IBANs or all at once

⚠️ Important Disclaimer

Generated IBANs are for testing purposes only. While they are mathematically valid and pass all format checks, they do not correspond to real bank accounts.

Never use generated IBANs for:

  • Actual financial transactions
  • Production payment processing
  • Real money transfers
  • Fraudulent activities

Always use legitimate IBANs provided by authorized financial institutions for real transactions.

Technical Details

Our generator creates IBANs using the following process:

  1. Retrieves the IBAN specification for the selected country
  2. Generates a random BBAN (Basic Bank Account Number) following the country's format
  3. Applies custom bank/branch codes if specified
  4. Calculates the correct check digits using the MOD-97 algorithm
  5. Validates the generated IBAN to ensure correctness
  6. Formats the IBAN according to country-specific standards
