Are you looking for an easy way to generate IBAN numbers for testing purposes or data validation? An IBAN generator is a tool that helps you create valid International Bank Account Numbers quickly and easily. This article explains what an IBAN generator is, how it works, and gives examples of how it is used.

Understanding IBAN

Before diving into generators, let’s first understand what IBAN is. IBAN stands for International Bank Account Number. It’s a standardized format for identifying bank accounts across different countries, mainly used in Europe and some parts of the Middle East and North Africa.

The IBAN consists of up to 34 alphanumeric characters:

  • A two-letter country code
  • Two check digits
  • The Basic Bank Account Number (BBAN)

Here’s an example of a valid IBAN: GB82 WEST 1234 5698 7654 32

The country code is ‘GB’ for the United Kingdom, followed by two check digits and the BBAN.

What is an IBAN Generator?

It is a software tool or online service that automatically generates valid IBAN numbers. These generated IBANs can be used for various purposes, such as:

  • Testing banking systems and applications
  • Generating dummy data for development and testing
  • Validating user input for IBANs

Using generator saves time and effort compared to manually creating IBANs and ensures the generated numbers are in a valid format.

How Does an IBAN Generator Work?

Most generators follow these steps to create IBAN numbers:

IBAN Generator Example Diagram
  1. The user selects the country for which they want to generate.
  2. The generator combines the country code, check digits, and a randomly generated BBAN according to the country’s IBAN format.
  3. The generator validates the created IBAN using the MOD-97-10 algorithm to ensure it’s a valid number.
  4. The valid generated IBAN is displayed to the user.

Some advanced IBAN generators may offer additional features like bulk generation of IBANs, customization of the BBAN format, or integration with other banking tools.

Using an IBAN Generator: Examples

Let’s look at a couple of examples of how you can use an IBAN generator:

Example 1: Testing a Banking Application

Suppose you’re developing a banking application that needs to validate user-entered IBANs. To thoroughly test your validation logic, you need a large set of valid and invalid IBANs. Instead of manually creating them, you can use an generator to quickly generate IBANs for various countries and test cases.

Example 2: Generating Dummy Data

If you’re working with banking data and need to populate your database with realistic but fake IBAN numbers for testing or demonstration purposes, an IBAN generator can be a handy tool. You can easily generate a large number of valid IBANs and insert them into your database.


An IBAN generator is a valuable tool for anyone working with international banking systems or data. It simplifies the process of creating valid IBANs, saving time and reducing the risk of errors. Whether you need to test applications, generate dummy data, or validate user input, generator can help streamline your workflows.

When using an IBAN generator, ensure you select the correct country and customize the settings according to your needs. Always validate the generated IBANs before using them in production environments.
