If you are a European Customer and have a valid VAT number you don't have to pay VAT on your purchases. When you enter the address of your country and your VAT number into your account, this tax will not be added.
What is VIES?
The VIES system ("VAT information exchange system") is a search engine (not a database) belonging to the European Commission. When searching the VIES, data are extracted from national VAT databases.
The result can appear in two ways, depending on whether the VAT data exists (valid) or not (invalid).
If you receive a valid reply, the VAT data appears on the VIES.
If the answer is invalid, the VAT number you are trying to validate is not listed in the relevant national database. This is due to one of the following reasons:
-VAT number does not exist
-The VAT number for transactions within the EU has not been activated
- registration has not been completed (in some countries separate transactions are required within the EU).
The changes do not always appear immediately in the national databases, in the VIES.
