The Schengen Information System (SIS) and your personal data

The Schengen Information System (SIS) is a computerised system of alerts on persons and objects which is managed and used jointly by all the Schengen States including Switzerland. It contains information on people wanted by the police or the courts, banned from entering the Schengen area or who are missing. It also contains information on stolen or missing objects so that they may be seized or used as evidence if found.

The second generation information system (SIS II), which provides enhanced functionalities, replaced SISone4all on 9 April 2013. To provide an idea of size, it is estimated that currently (June 2017), SIS II contains around 53 million records on stolen or missing objects for seizure or use as evidence and over 1.5 million alerts on persons.

Everyone has the right to be given information on whether data concerning them is being stored in the SIS and, if so, to have access to this data, to have them corrected or deleted. Please consult our leaflet "Schengen and your personal data" for further information. Model letters are also available.
