About IBANs
What is an IBAN?
International Bank Account Number (IBAN) is a standard international numbering system for identifying bank accounts across national borders.
Testing Only
All IBANs generated are for testing and development purposes only. They follow the correct format but don't represent real bank accounts.

Understanding IBAN Structure
International Bank Account Numbers (IBANs) follow a standardized format that varies by country. Each IBAN consists of:
- Country Code: A two-letter ISO country code (e.g., GB for United Kingdom)
- Check Digits: Two digits calculated using the MOD-97 algorithm
- Basic Bank Account Number (BBAN): Country-specific format including:
- Bank identifier code
- Branch code (sort code in UK)
- Account number

Frequently Asked Questions
What is an IBAN?
IBAN (International Bank Account Number) is an internationally standardized format for bank account numbers. It consists of a country code, check digits, and a country-specific account identifier, making international transfers easier and more reliable.
Are these IBANs real?
No, the IBANs generated by this tool are for testing purposes only. While they follow the correct format and pass validation checks, they do not correspond to real bank accounts and cannot be used for actual transactions.
How accurate are the generated IBANs?
Our IBANs are 100% structurally valid. They follow ISO 13616 standards, include correct country codes, proper length, valid check digits (mod-97), and country-specific formatting rules.
Can I use these for testing?
Yes! These IBANs are perfect for software testing, development environments, form validation testing, UI/UX mockups, and educational purposes. They will pass standard IBAN validation algorithms.
Do you have an API?
Yes, we offer a comprehensive API for generating IBANs, validating them, and retrieving IBAN structure information. Check our API documentation for integration details.
Technical Details
IBAN Structure Compliance
All generated IBANs strictly adhere to the ISO 13616 standard, ensuring:
- • Correct country-specific length
- • Valid bank and branch codes
- • MOD-97 checksum validation
- • Proper character set usage
- • Standardized formatting
Generation Algorithm
Our generator creates IBANs using a multi-step process:
- 1. Construct country-specific BBAN with valid bank codes
- 2. Calculate check digits using MOD-97 operation
- 3. Combine country code, check digits, and BBAN
- 4. Format according to country standards
- 5. Verify structural validity
