VAT Number Validator checks whether a VAT number is valid. Send a single vat value in the request body, including the 2-letter country code prefix, and you get back a boolean data field indicating the result.
Use it when you need to verify tax identifiers before invoicing, onboarding a customer, or accepting a business registration number in a checkout or account flow. It fits cleanly into form validation, billing systems, and back-office compliance checks where you only need a yes-or-no answer.
The API keeps the response simple: data is true for a valid VAT number and false otherwise. That makes it easy to branch logic without parsing extra metadata or country-specific lookup fields.
If your product collects business details across multiple EU markets, VAT Number Validator gives you a consistent validation step for every submission.
Validate a VAT number by sending it in a JSON body.
