Generate random European IBAN

Generate structurally valid sample IBANs for testing, demos, and UI validation without using real bank details. The tool builds the result from the official structure of the selected country: ISO country code, check digits, and total IBAN length.

How it's generated

An IBAN combines a country code, two check digits, and a national BBAN. For each supported country, Tool Plaza applies the correct length and a template compatible with the most common structural rules for that country. It then computes the check digits with the MOD 97 algorithm, the same method used in international IBAN validation.

When to use it

Populate test environments, create documentation examples, verify that a form accepts the correct format, or prepare sample data for banking or ERP integrations.

Limitations

The result can be structurally valid but does not represent a bank account issued by a real institution. A bank may require additional checks on the national BBAN or on whether the account actually exists. Do not use IBANs generated here for real transfers.

Example

Choosing DE produces an IBAN with the German length and MOD 97-compatible check digits. You can then paste the result into the IBAN verification tool or the by-country validation tool to test the full flow.
