Electronic Exchange of Social Security Information (EESSI)

EESSI is an IT system that helps social security institutions across the EU exchange information related to different branches like applicable legislation, sickness, occupational diseases and accidents at work, pensions, unemployment and family benefits more rapidly and securely, as required by the EU rules on social security coordination.

Thus while the system is used by institutions among themselves, you, as a citizen, benefit from these electronic exchanges as in the past, before EESSI, those were paper-based. It was time-consuming and prone to errors and a loss of data or documents.

Please note that for a direct digital experience between a citizen and an institution in an EU country, another solution, called European Social Security Pass, is being piloted and will deliver its first results during the first half of 2022.

How EESSI works

All communication between national institutions on social security files are to take place through EESSI: social security institutions exchange structured electronic documents and follow commonly agreed procedures to process them. These documents are routed through EESSI to the correct destination in the right institutions in another Member State. Staff in social security institutions are able to find the correct destination in participating countries by consulting a repository of national institutions.

Benefits of EESSI

Faster and more efficient information exchange between social security institutions benefits to mobile citizens

  • EESSI speeds up exchanges between social security institutions on cases related to different branches of social security (such as unemployment, family, old-age pension, sickness benefits, accidents at work etc.). It allows them to handle individual cases more quickly, and helps make calculation and payment of benefits faster.
  • This faster and more efficient exchange of social security information helps enhance the protection of the social security rights of citizens across borders.

More accurate data exchange between national authorities

  • Social security institutions across the EU use standardised electronic documents translated into their own language, improving multilingual communication.
  • EESSI optimises case handling, introducing standard electronic procedures to be followed by institutions. This helps ensuring that social security coordination rules are correctly applied.

Fight against fraud

  • EESSI introduces safeguards to ensure that the data exchanged is correct and complete, helping institutions to combat fraud and error.

Secure handling of personal data

  • EESSI uses a common secure infrastructure for cross-border data exchange between social security institutions.
  • It enables message exchange between national institutions, but the system does not create a database to store such messages and personal data centrally. The content of the messages is only available to the relevant institutions, and Member States remain responsible to ensure a high standard of data protection, in line with EU rules.
  • EESSI follows the latest standards in IT security.

Collect statistics about social security coordination

  • EESSI enables to collect statistics on the message exchanges between social security institutions.

Verification of social security rights

  • Social security institutions across Europe can exchange relevant information also to verify the social security rights of mobile citizens.
