Electronic Exchange of Social Security Information (EESSI)

This is a CEF funded Sector Specific Digital Service Infrastructures (DSIs). It deploys complex trans-European digital services based upon mature technical and organisational solutions in diverse areas.

The EU provides common rules to protect the social security rights of persons when moving within Europe (28 EU Member States as well as Iceland, Liechtenstein, Norway and Switzerland). In order to determine the social security rights of persons in a cross-border situation, the competent national institutions have to exchange relevant information in the framework of the coordination of national social security systems, and according to the EU rules these exchanges across borders should be done electronically.

At the moment there is no EU-wide electronic system in this field, and most exchanges are still paper-based. The communication between institutions therefore does not take advantage of the benefits of modern technologies and is not carried out in the most efficient way.

What is this DSI?

This Digital Service Infrastructure is an IT system – EESSI - that will help institutions across Europe to exchange information needed for the social security coordination more rapidly and securely. The exchanged information will cover all branches of EU rules on social security coordination, such as sickness benefits, accidents at work and occupational disease benefits, family benefits, old-age pensions, pre-retirement and invalidity benefits, unemployment benefits.

EESSI is a central platform to which the national institutions will have to connect to be able to exchange information between each other. These institutions will use the system to route structured electronic documents to their counterparties following agreed business processes

What is the Policy Context?

The set-up of EESSI is compliant with Regulations (EC) No. 883/2004 and 987/2009 for the coordination of social security systems, which establish the obligation for the participating countries to exchange social security coordination data electronically after a transition phase.

What's in it for me?

Are you a EU resident living, working or travelling in another EU country?

You can benefit of a strengthened protection of your social security rights through a faster management of your applications and faster calculation and payment of your benefits in accordance with the applicable EU law on social security coordination.

Are you a national social security administration?

You can benefit of a secure, efficient, accurate and standardised data exchange in cross-border social security coordination cases. An enhanced and more effective communication process is expected thus to reduce administrative burden and shorten the duration of case handling.
