MISSOC, 'Mutual Information System on Social Protection', is a network of the European Committee, established in 1990 to promote a continuous exchange of information on social protection among the EU Member States. The system nowadays includes information on Social Protection in the 28 Member States of the European Union, as well as Iceland, Liechtenstein, Norway and Switzerland.

MISSOC has grown into a central knowledge and information base for public authorities, professional users and European citizens, providing up-to-date information on social protection legislation, benefits and conditions in all participating countries. On the one hand, the information base allows users to find descriptive or detailed information about a specific country. On the other hand, the system offers the opportunity to compare and analyse several social protection systems.

MISSOC is based on a close cooperation between:

• the European Commission: Directorate General for Employment, Social Affairs and Inclusion, Unit D/3 Active Ageing, Pensions, Healthcare, Social Services
• the National Correspondents: a network of official representatives from the national ministries or institutions that are responsible for the area of social protection
• the MISSOC Secretariat: a team of experts appointed by the European Commission
