As of 15 October 2026, Member States can enter a new type of information alert in the Schengen Information System (SIS). The new alert allows information received from non-EU countries and international organisations on third-country nationals suspected of involvement in terrorism or serious crime to be made available to authorities across the countries using the system.

The migration of data from SIS I to SIS II has started as the second generation Schengen Information System (SIS II) is today replacing the current system.
