Detailed information

This service is particularly interesting for B2B transactions. We provide you with an interface to the European Commission with which you can check the VAT identification number. The European Commission calls this the "VAT Information Exchange System".


The highlight is that not only is the check digit and syntax checked, but - in our extended version VATIDX - the company name and address are also returned. Unfortunately, this is not the case for Germany, but for most other countries. Below are a few examples for testing.

And best of all: You get this check free of charge!!! Unfortunately, we cannot guarantee that the server of the European Commission is always available. That is not in our hands.

The VAT identification numberThis number is particularly interesting for entrepreneurs who offer or purchase their goods and/or services across European national borders. The VAT identification number (USt-IDNr.) is issued on application by the Federal Central Tax Office on the basis of the legal provisions of § 27a UStG. It enables a VAT payer to be unambiguously identified and is used within the European Single Market for the settlement of accrued VAT by the tax offices. This is to ensure taxation of intra-Community acquisitions.

To test it, simply register with Adresslabor free of charge and without obligation and try it out with the starting credit of 1,000 credits. You are under no obligation whatsoever. 

Since this is a European topic, here are the appropriate search terms for some countries, in case you want to do some googling yourself: 

VAT ID (value added tax identification number)

ID TVA (Numéro d'identification TVA) 

IVA (número de identificación a efectos del IVA)

P.IVA (numero di partita IVA)
