European VAT Check Service

Connection to European Community VIES web-service (VAT Information Exchange System) to check if an operator VAT number is valid.

Allows you to verify hundreds of VAT identification numbers issued by an European Member State. The verification is done against the national VAT database corresponding to the selected Member State. There is no VAT database at European Community level. In order to verify VAT numbers, your request is sent to the national database via a secure Intranet service connecting national Customs and Taxation administrations and the reply is sent back in a few seconds.

European VAT Check Service is useful for companies having to verify the VAT Numbers of many customers and/or suppliers, for example before billing, and allows:

  • Single-click verification of hundreds of VAT identification numbers got from external data sources.
  • To get "VIES Request ID", unique consultation number useful if you have to prove to a tax administration of a Member State that you have checked a given VAT number.
  • To print and/or export results to file.

You can install this application on Windows Seven, Windows 10 o later versions. Operational requirement is an Internet connection. If your Internet connection uses a proxy, you have to configure it to allow conversation between software and VIES web-service.


When You click on the "Verify" button get the following possible answers:

  • Yes, valid VAT number.
  • No, invalid VAT number (meaning that the number introduced is not valid at least on the date specified).
  • Service unavailable. Please re-submit your request later. (meaning there is some problem with either the network or the Web application).
  • Member State service unavailable. Please re-submit your request later.(meaning the application in the Member State whose VAT number you are trying to validate is not available).
  • Error: Incomplete (VAT + Member State) or corrupted data input.
  • Request time-out. Please re-submit your request later.
In the case of a valid VAT number, if the name and/or address are missing, this means that the Member State that issued the VAT number does not allow to disclose this information. If you put your own VAT identification number in the box requester's VAT identification number, the reply will contain a unique consultation number.
