Estonia and Finland are the first two nations in Europe to develop a joint data exchange platform based on Estonia’s X-Road, which allows databases in both countries to interface, assist with cross-border services, and make e-services accessible to Estonian and Finnish citizens.
In Estonia, the entire process is operated by the Information System Authority (RIA), and in Finland by VRK, the Population Register Centre, which is subject to the finance ministry. According to RIA, even entrepreneurs operating in Latvia have started discussing the option of using e-services in Latvia.
X-Road, which has been used in Estonia since 2001, is a layer of services organising data exchange between agencies, thereby granting citizens and public servants access to state databases as one integrated entity. In Estonia, over a million queries for information are submitted via X-Road daily.
