The Schengen Information System (SIS), Europe’s largest and most widely used information-sharing system for security and border management, continued to play a central role in supporting operational cooperation across Europe in 2025, according to the latest annual statistics published by eu-LISA.
The newly released figures show that national authorities and EU agencies performed more than 17.7 billion searches in SIS in 2025, representing an 18% increase compared to 2024. On average, this amounts to nearly 49 million searches every day, highlighting the system’s critical role in enabling authorities to access and exchange information quickly and securely across borders.
By the end of 2025, SIS contained over 94.6 million alerts, including alerts on wanted or missing persons, return decisions, refused entry and stay, as well as alerts on stolen or lost objects such as vehicles, identity documents and licence plates. This represents a 2% increase compared to the previous year.
Operational cooperation supported through SIS remained significant throughout the year. In 2025, Member States reported nearly 365,000 hits on foreign alerts through the SIRENE Bureaux network, helping authorities take action in cross-border cases involving law enforcement, migration management and judicial cooperation. On average, this meant around 1,000 hits per day across Europe.
The figures also reflect the growing importance of biometric capabilities in SIS. More than 13.1 million biometric searches were performed in 2025, an 88% increase compared to 2024, demonstrating the expanding use of advanced identification tools to support accurate and efficient checks.
Alerts on persons continued to grow significantly, reaching nearly 2 million records by the end of the year, a 19% increase compared to 2024. Alerts related to third-country nationals subject to return decisions remained the largest category, underlining SIS’s continued contribution to supporting the implementation of EU migration and return policies.
As the operational manager of the central SIS infrastructure, eu-LISA ensures the continuous availability, security and development of the system, enabling national authorities and relevant EU agencies to rely on fast and secure information exchange in support of Europe’s internal security and effective border management.
