The Schengen Information System (SIS) was used by the Member States of the EU more than 7 billion times in 2021.
At the end of last year there were more than 89 million alerts stored in the system. The biggest share of alerts (75%) were about objects and 1% was about persons. Similarly to past years, the majority of person related alerts were about third-country nationals to be refused entry or stay within the Schengen Area. More than 222 thousand hits on person related alerts were reported. The majority of hits were triggered by alerts on persons and objects requiring discreet or specific checks.
The Schengen Information System is a large-scale information sharing system for security and external border management in Europe, that offers essential support to providing internal security throughout the Schengen Area.
As people and goods can move freely in the Schengen Area without being checked at internal borders, SIS is used by security officials of the Member States, thus ensuring a high level of security and contributing to law enforcement and judicial cooperation across Europe.
eu-LISA is in charge of the operational management of the central system and its communication infrastructure, ensuring agile project management for its timely evolution and 24/7 operational monitoring support.
