Invalid VAT number in VIES

An invalid VIES result means VIES did not confirm the number as registered for intra-EU transactions at the time of the check.

Common reasons

The number may not exist, may not be activated for intra-EU transactions, or the registration may not yet be finalised in the national database.

Ask the customer to confirm the exact VAT ID and whether their local tax authority has activated it for cross-border EU transactions.

Check a VAT number

You can paste the full VAT ID with country prefix, or choose the country and enter the local number.
