The European Commission launches the Once-Only Hub

This Hub is a platform where national teams from the EU Member States (Implementers) will work to realise the Once-Only Technical System, which implements the Once-Only Principle.

It is also a resource for journalists, academics, students, interested parties and citizens who want to learn more about the Once-Only Technical System and the ‘Once-Only’ principle.

The Once-Only Technical System (OOTS) enables the sharing of information between public administrations across borders between EU countries. It is cross-sectorial and can be expanded beyond the current scope of life events set out in the Single Digital Gateway Regulation (EU) 2018/1724.

The Once-Only Technical System the technical and operational specifications of the technical system are laid out in the Implementing Regulation (EU) 2022/1463.

Notably for the Once-Only Technical System, the Member States will use the eID building block to authenticate users from different countries, and the eDelivery building block for the automated cross-border sharing of data (legally referred to as “evidence”), achieving maximum efficiency games.

You can learn more about the Once-Only Technical System on the Once-Only Hub.
