VAT number check
Validate an EU customer's VAT number against the official VIES service before you zero rate a cross border supply, and keep the result with your records.
- Pick the country and enter the number without the country prefix.
- We query the official EU VIES service, no account or paid API needed.
- Valid numbers return the registered name and address where the member state releases them.
- Save the result and date as evidence for your zero rating.
Does this check UK VAT numbers?
VIES covers EU member states. Since Brexit, GB numbers are not in VIES, use the HMRC checker for GB numbers. Northern Ireland XI numbers are still in VIES.
Why does a valid number matter?
Zero rating an intra EU supply depends on a valid customer VAT number at the time of supply. Without evidence the tax authority can assess the VAT on you.
What if no name is shown?
Some member states do not release the trader name and address. The number can still be valid.
How often should I re-check?
Check new customers before the first invoice and re-check regular customers periodically, monthly or quarterly is common practice.
