What Cleiss - Centre des liaisons européennes et internationales de sécurité sociale does

Cleiss (Centre des Liaisons Européennes et Internationales de Sécurité Sociale) is a French national public establishment (établissement public national) operating under the dual oversight of the Ministry of Social Security and the Ministry of Budget. Founded in 1959 as the Centre de Sécurité Sociale des Travailleurs Migrants (CSSTM) and renamed in 2002, its statutory mission is to inform individuals, employers, and self-employed workers about social protection rights in the context of international mobility. It coordinates France's position vis-à-vis EU social security regulations, bilateral agreements with approximately 90 countries, and CJEU jurisprudence, while also serving as France's designated National Contact Point for cross-border healthcare under EU Directive 2011/24/EU.

Its core "products" are informational rather than technological: a multilingual (7-language) website (cleiss.fr) structured around departure-from-France and arrival-in-France scenarios, country fact sheets covering ~90 jurisdictions, an extensive FAQ, the annual Rapport Statistique (the unique French record of international social protection financial flows), Décryptage analytical publications, and direct telephone/email guidance. Its only operational IT asset is the ODSS (Ouverture du Droit aux Soins de Santé) administrative database, used to track beneficiaries of French pension/rent schemes residing abroad and to control E 127 reimbursement claims from foreign health insurance funds under EU regulations 1408/71 and 574/72. The organization distributes via its website, social media (X, YouTube, LinkedIn), RSS feeds, email newsletters, participation in expat salons, and — as of May 2026 — through the EURES France network.

Cleiss does not operate as a commercial entity. It is funded by a fixed percentage-based allocation from six French social security regimes (CNAM, CNAF, CNAV, CCMSA, ACOSS, CANAM) as set by Décret n° 2002-1588 of December 24, 2002. All publications, statistical reports, and guidance are provided free of charge, and no pricing model, products, APIs, or commercial transactions exist. Governance is exercised through a Board of Directors with representatives from the contributing social security funds, under multi-year Convention d'Objectifs et de Gestion (current cycle 2025-2028) with the French government.

Revenue model

1. Public institutional funding: CLEISS is financed through contributions from French social security schemes (régimes de sécurité sociale), allocated via a percentage-based distribution key set by ministerial order. The funding mechanism was simplified under the 2002 decree (Décret n° 2002-1588), replacing an annual recalculation with a fixed percentage allocation between contributing regimes (CNAM, CNAF, CNAV, CCMSA, ACOSS, CANAM). This is institutional/government funding, not commercial revenue.

Scale indicators2 records

Recent moves7 records

Broad incumbents

• European Commission DG Employment, Social Affairs and Inclusion (DG EMPL): DG EMPL is the EU-level directorate-general responsible for employment and social policy coordination, including oversight of EU regulations 1408/71 and 883/2004 that underpin CLEISS's work. It is a broad incumbent that defines the regulatory framework CLEISS implements at national level, making it the closest EU-level institutional peer.
• European Commission DG SANTE (Health and Food Safety): DG SANTE oversees EU cross-border healthcare policy, including Directive 2011/24/EU under which CLEISS serves as France's National Contact Point. It is directly comparable as the EU-level counterpart to CLEISS's healthcare-coordination role, with overlapping responsibilities for portable healthcare documentation (CEAM) and patient mobility.

Others

• Caisse Nationale d'Assurance Vieillesse (CNAV): CNAV is the French national pension regime that operates the ODSS database jointly with CLEISS and is one of its contributing regimes. It is an adjacent institutional peer because it handles international pension payments and bilateral coordination at the operational level, complementing CLEISS's informational role.
• European Insurance and Occupational Pensions Authority (EIOPA): EIOPA is the EU-level regulator for insurance and occupational pensions. It is thematically related to CLEISS because cross-border pension coordination is one of CLEISS's core informational domains; however, EIOPA focuses on prudential supervision rather than individual applicant guidance, making it an adjacent enabling institution rather than a direct competitor.
• European Social Insurance Platform (ESIP): ESIP is a Brussels-based association of national statutory social security organizations across the EU. It is thematically related to CLEISS because ESIP members perform the same coordination function for their countries that CLEISS performs for France, providing a forum for shared regulatory intelligence and policy advocacy on cross-border social security matters.
• Caisse Nationale d'Assurance Maladie (CNAM): CNAM is the principal French health insurance regime and one of CLEISS's institutional funders and operational partners. It is comparable as an adjacent French social security body with overlapping subject-matter expertise in cross-border healthcare reimbursements and CEAM administration through its international liaison function.

Direct peers

• Mutual Information System on Social Protection (MISSOC): MISSOC is the EU's comparative information system on social protection across member states, maintained by the European Commission. It is a direct peer because it provides cross-border comparative information on national social security systems — closely mirroring CLEISS's country fact sheets — and serves the same audience of mobile workers, employers, and institutional users.
• National Contact Points for Cross-Border Healthcare (other EU member states): Each EU member state designates a National Contact Point under Directive 2011/24/EU. These national contact points (e.g., Punto di contatto nazionale in Italy, Punto Nacional de Contacto in Spain) share CLEISS's exact mandate for cross-border healthcare information and are therefore its most direct functional peers within the EU healthcare coordination network.
• EURES (European Employment Services): EURES is the European cooperation network of employment services for cross-border labor mobility, of which CLEISS became a member in May 2026. It is directly comparable because both entities serve mobile workers navigating cross-border employment and social security rules across EU/EEA countries, with overlapping informational mandates on applicable legislation and posted worker rights.
• Deutsche Verbindungsstelle Krankenversicherung – Ausland (DVKA): DVKA is Germany's national liaison body for healthcare insurance abroad, performing the same liaison role for Germany that CLEISS performs for France under EU social security coordination regulations. It is a direct peer because both institutions coordinate cross-border health insurance reimbursements, portable documents (EHIC), and bilateral agreements with non-EU countries.
