Goal
Help citizens and businesses to study, move, work, retire or do business across the EU. The OOTS connect public authorities across the EU, so they can exchange official documents and data at the citizen or business' request.
How?
Member States are consulting their competent authorities to determine which procedures require the exchange of evidence across borders. Each Member State provides a service to request evidence and another one to provide evidence.
Since 2020, the Your Europe portal provides useful information about online public services available in each Member State e.g., for studying, working or retiring abroad.
Since 2023, the data space, known as the "Once-Only Technical System", has been operational. As national authorities across the EU begin to use it, the OOTS will significantly ease and speed up the cross-border administrative procedures.
Regulation
The Single Digital Gateway Regulation ((EU) 2018/1724) provides the legal framework for the creation of a European data space for public administration (a digital infrastructure) to share information.
A specific Implementing Regulation ((EU) 2022/1463) sets out the technical and operational specifications of the technical system.
