eu-validate mock-data generator
Generate realistic valid and invalid EU test identifiers for your integration and unit tests — VAT, IBAN, BSN and KvK. Every value is verified against the library in your browser before it is shown.
Country
Valid
— Invalid
— Generated client-side and verified against @alosha/eu-validate — the valid value passes the matching validator, the invalid value fails it. Nothing is sent anywhere.
