VAT Number Validator checks whether a VAT number is valid. Send a VAT value in the request body, including the 2-letter country code prefix, and get a boolean result back in data.
Use it when you need to confirm a customer, supplier, or invoice tax ID before storing it, billing against it, or passing it into another workflow. The service is focused on a single check, so the response stays simple and easy to consume in validation flows.
The request schema only accepts one field: vat. The response schema only returns data, which is true or false depending on the result. That makes it a good fit for signup forms, tax compliance checks, and order systems that need a quick VAT verification step without extra parsing.
Validate a VAT number by sending it in a simple JSON body.
