How your checks work
A result for every row
VAT numbers are checked against VIES, the EU's VAT number service. Repeated numbers are checked once, but every row appears in your download. Numbers we can't check are clearly marked so you can fix them.
When a check can't be completed
“Could not check” means the service couldn't give an answer. It doesn't mean the number is invalid. For real checks, we try again automatically. You can also retry within 24 hours at no extra cost, up to six attempts per number. Some countries don't return a company name or address, even for a valid number.
One payment for your whole list
Bulk checking costs €19 for up to 100 rows, including a downloadable report and retries. You can check one VAT number for free using our single-number checker. Payment is by card through Stripe, and Stripe emails your receipt.

If we can’t complete your checks
A full refund applies if fewer than 90% of the numbers we can submit get a valid or invalid result within 24 hours. Cancelling before that level is reached also qualifies. Repeated numbers count once, and rows we can’t submit aren’t included. A refund is complete when the payment service confirms it.
Keep a copy of your results
Your results are saved for 30 days. Download a copy if you need them for longer, or remove them earlier. Open saved results in the same browser you used to create them. Clearing that browser's cookies removes your access, so download anything you need first.
Your list stays private
We don't keep the original CSV file. The VAT numbers, your references and the results are saved securely with encryption and aren't sent to our analytics services. Payment records may need to be kept until a refund is complete.
A valid VAT number isn't a tax clearance certificate and doesn't tell you which VAT rate to charge. Read the EU's guide to VAT number checks.
