How to use VIES verification?

To check a contractor in the VIES system, you must provide the EU Member State of origin and its EU VAT number.
The results that can be obtained from the system are confirmation that the VAT number is active or information that the VAT number for cross-border transactions within the European Union is invalid.

Depending on their national data protection laws, some country will also provide the name and address associated with a given EU VAT number as they are registered in national databases.

Information available on VIES is not correct. How to correct it?

If a VAT number is shown as invalid, in the first instance check with your customer that the number quoted is correct (correct number of characters, correct length and country prefix). If the number quoted by your customer, even after checking, continues to be ‘invalid’, you should ask that business to contact his/her tax administration to request that the data in the national VAT Information Exchange System (VIES) be updated (only national tax administrations can update VIES data).

What period of time is the information available?

Only confirmation on whether or not a number is valid. It is not possible to confirm the validity of a VAT number in the past. It is possible to do it only for the current day.

VIES did not find the company, why?

If it turns out that the VIES search engine has not found the given VAT number, it is possible that the VAT number does not exist, has not been activated for EU transactions, the registration of the number has not yet been completed or the entity has been removed from the database of EU taxpayers.
Of course, first of all, it is worth making sure that we have entered the VAT-EU number correctly, or contact the contractor and ask if the number is correct. If he maintains that the data provided is correct, and VIES indicates otherwise, the entrepreneur should contact the tax administration in order to clarify this situation or update the data.
