-## Requirements
+## GDPR and privacy regulation of VAT within the EU
+
+On May 25, 2018 the General Data Protection Regulation or GDPR becomes law within all 28 European Member States. Is this VIES service package going to be compliant with GDPR? 
+
+In short: yes. 
+
+The longer answer is that this VIES package only interacts with the service for VAT ID verification provided by the European Commission. VAT validation is mandatory in European countries and therefor this service is allowed as lawfulness and legal basis. Please read more about this in [European DPO-3816.1](http://ec.europa.eu/dpo-register/details.htm?id=40647). This service does not store any data itself or collects more information than what's strictly required by law and provided by the EC VIES service.

+When you have implemented this service package in your own project, be sure that you're making sure you're just store the VAT ID, the timestamp of validation, the result of validation and optionally the given validation ID provided by the EC VIES service.
