About Us

Check VAT Number is a free online service that helps businesses and professionals verify EU and UK VAT registration numbers before they invoice, contract, or pay a supplier.

Our mission

We believe VAT validation should be simple, fast, and accessible to everyone. Our tool connects directly to official government sources — the European Commission VIES system for EU member states and HMRC for UK (GB) numbers — so you get authoritative results without signing up or paying a fee.

What we offer

Enter any VAT number with its country prefix and receive an instant valid or invalid result, along with the registered business name and address where available. Whether you are checking a UK supplier, an Irish customer, or any EU trading partner, Check VAT Number gives you the confidence to transact safely.

Who we serve

Our users include small business owners, accountants, bookkeepers, e-commerce sellers, and finance teams who need a quick due-diligence check before B2B transactions. We are independent and not affiliated with any tax authority.
