DigiD (Digital identity)
DigiD is an identity management platform which government agencies of the Netherlands, including the Tax and Customs Administration and Dienst Uitvoering Onderwijs, can use to verify the identity of Dutch residents on the Internet. In 2015 it was used for 200 million authentications by 12 million citizens. The system is tied to the Dutch national identification number (burgerservicenummer, BSN). The system has been mandatory when submitting tax forms electronically since 2006.
