VIES (VAT Information Exchange System) enquiries

What is VIES and how it works

With the introduction of the single market on 1 January 1993 , fiscal customs based controls at internal frontiers were abolished and a new VAT control system was put in place for intra-Community trade. The most significant benefit was the reduction of the administrative burden on companies; with the elimination of some 60 million customs documents per annum.

Under the new VAT system intra-Community supplies of goods are exempt from VAT in the Member State of despatch when they are made to a taxable person in another Member State who will account for the VAT on arrival. Therefore any taxable person making such supplies must be able to check quickly and easily that their customers in another Member State are taxable persons and do hold a valid VAT identification number. For that purpose, inter alia, each tax administration maintains an electronic database containing the VAT registration data of its traders. Such information includes the VAT identification number, the trader's name, the trader's address.

A computerised VAT Information Exchange System (V.I.E.S.) was set up to allow for the flow of the data held across the internal frontiers which:

  • enables companies to obtain rapidly confirmation of the VAT numbers of their trading partners
  • Enables VAT administrations to monitor and control the flow of intra-Community trade to detect all kinds of irregularities

The unit responsible for the control of intra-Community trade in each Member State , the Central Liaison Office (CLO), has a direct access through VIES to the VAT registration database of the other Member States.

National Access Mechanism

Traders, making an enquiry as to whether a particular VAT number is valid or whether it is correctly associated with a specified trader name and/or address, gain access to the VAT registration verification system through their national CLO, which will give one of the following replies:

  • Yes, valid VAT number
  • No, invalid VAT number
  • Yes, the VAT number is associated with a given name/address
  • No, the VAT number is not associated with a given name/address

(N.B. For security and data protection reasons, the national administrations will not supply the name and address in relation to a valid number).

The methods used in the Member States to deal with trader enquiries differ significantly. Some have implemented on-line systems to automate traders' access to the information while others have administrative units that answer traders' inquiries made by phone, mail or fax

This web application

The European Commission maintains this website to enhance access by taxable persons making intra-Community supplies to verification of their customers' VAT identification numbers. Our goal is to supply instantaneous and accurate information. A real time response is obtained for any user querying an EU VAT number in a specified EU country. To aid the user in navigating the site it gives some warning or help messages in all eleven EU languages. This web site is open to anyone and gives a similiar service to the national systems, providing a "yes" or "no" answer to the user for the first two questions only.

These national web sites offer similar services: Germany (for German Taxable persons only), Italy and Spain (to check Spanish numbers only).
