Schengen Information System

The Schengen Information System (SIS) is a governmental database under the responsibility of the European Commission. The SIS is used by 26 European countries to maintain and distribute information about individuals and entities. The intended uses of this system are for national security, border control and law enforcement. A second technical version of this system, SIS II, went live as scheduled on 9 April 2013.

Information in SIS is shared among institutions of the countries participating in the Schengen Agreement Application Convention (SAAC). The five original participating countries were France, Germany, Belgium, the Netherlands, and Luxembourg. 21 additional countries have joined the system since its creation: Spain, Portugal, Italy, Austria, Greece, Finland, Sweden, Switzerland, Denmark, Iceland, Norway, Estonia, the Czech Republic, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia and Liechtenstein. Among the current participants, Iceland, Liechtenstein, Norway, and Switzerland are not members of the European Union.
