EU VAT Number Validator - VIES Verification

Controleer EU BTW-nummers via de officiële VIES Database

Verify EU VAT (BTW) numbers against the official VIES database. Essential for intra-EU invoicing, reverse charge mechanism, and ICP reporting. Check if your client's VAT number is valid before issuing invoices.

Why validate VAT numbers?

When invoicing businesses in other EU countries without charging VAT (reverse charge / verlegde BTW), you must verify the client's VAT number. Invalid numbers can make you liable for the VAT amount.
