Did you know?
International Bank Account Numbers (IBANs) use a check digit system based on Modulo 97 to prevent transcription errors. The first two letters identify the country, followed by two check digits, and then the Basic Bank Account Number (BBAN).

An IBAN (International Bank Account Number) is a standardized international numbering system used to identify bank accounts across national borders. IBANs contain up to 34 alphanumeric characters including a country code, check digits, and the domestic bank account number. This generator creates valid-format IBAN numbers for testing payment systems, banking integrations, and financial software.
IBANs are used in over 80 countries and are mandatory for cross-border transfers within the EU/EEA via SEPA. The check digit mechanism (MOD 97-10) ensures transmission errors are caught before processing, making IBANs more reliable than raw account numbers.
Common Use Cases
Payment Gateway Testing
Generate valid-format IBANs to test SEPA direct debit, wire transfer, and payment processing integrations without using real bank accounts.
Banking Software QA
Populate test databases with realistic IBAN data for validating account input forms, statement generation, and reconciliation workflows.
Compliance Testing
Test KYC/AML validation pipelines with properly formatted international account numbers across multiple country formats.
API Integration Testing
Use generated IBANs to test third-party banking APIs like Plaid, Stripe, or GoCardless in sandbox environments.
Frequently Asked Questions
Are these IBANs real bank accounts?
No. Generated IBANs follow the correct format and pass check-digit validation, but they are not linked to any real bank accounts. They are designed for testing and development purposes only.
Which countries are supported?
This generator supports IBAN formats for all major countries including DE (Germany), GB (UK), FR (France), ES (Spain), IT (Italy), NL (Netherlands), and many more.
Do generated IBANs pass validation?
Yes. Each IBAN is generated with correct country-specific formatting and valid MOD 97-10 check digits, so they pass standard IBAN validation algorithms.
