The once-only principle is in use around the European Union in many different sectors and domains. In order to share the expertise of stakeholders and to display how the once-only principle can be applied, we have created the once-only project map to display the current state of once-only in the EU. 

By clicking on the map of Europe you can discover the individual cases and enablers of once-only. By using the filters, you can search for cases that apply only to the domain you are interested in such as education, business, health or mobility. The map will provide you with basic information about the case/enabler - for more detailed background information you can register to our website to find out more. 

Please feel free to share the map with your network and let us know what you think!
