<p>On 18-20 October 2023, the third Once-Only Technical System Projectathon brought together 24 EU Member States for a marathon of peer-to-peer interoperability testing. This was the final of three such events in 2023. Projectathons facilitate crucial development, testing and eventual deployment of national Once-Only Technical System implementations.</p>
<p>This Projectathon was a major milestone, coming two months before the legal deadline for Member States to implement the Once-Only Technical System. This deadline is set out in the Single Digital Gateway Regulation, which expressly calls for the creation of this Technical System to help digitalise the internal market.</p>
<p>In addition to testing, Member States experts collaborated on improving the Once-Only Technical System user experience, learned about lifecycle management for the Once-Only Common Services, updates to the Semantic Repository. Moreover, Austria, the Netherlands and Germany presented how they are piloting the Once-Only Technical System in the business sector.</p>
<p>The Once-Only Technical System lets EU public authorities securely exchange official documents and data at the request of citizens and businesses as part of cross-border administrative procedures, e.g., when registering an address or vehicle when moving abroad. Once-Only eliminates the often complex manual search, mapping, and fetching of data between Member State authorities. Once-Only improves efficiency, makes people's lives easier, and reduces the costs of mobility within the Single Market.</p>
<p>On the first day of the October Projectathon, participating Member States executed more tests between their national Once-Only implementations than during the entire June 2023 Projectathon, clearly highlighting the great value of such events.</p>
<p>The Commission will publish an event report for the October Projectathon shortly.

<p>Following this Projectathon, the focus now turns to the go-live of the Once-Only Technical System and its operational deployment.</p>
