The borderless Schengen area guarantees free movement to tens of millions of EU citizens, residents and visitors.

It recently celebrated its 40th anniversary, and after originally starting with just five countries signing a convention pledging to “gradually abolish” internal borders checks and allow people to travel around freely, today the Schengen area includes 25 of the 27 EU member states and the four countries of the European Free Trade Association (Iceland, Liechtenstein, Norway and Switzerland).

According to the EU Council website, the Schengen area covers over 4.5 million square kilometres with a total population of almost 450 million people. Every day around 3.5 million people cross the Schengen internal borders for work, study or visits, and almost 1.7 million people reside in one Schengen country while working in another.

Under the Schengen Borders Code, which sets the rules governing the Schengen area, internal border checks can be temporarily restored where there is a “serious threat to public policy or internal security”, from the organisation of a major sport event to a terrorist attack.

These checks should be a “last resort” measure, should be limited to the period “strictly necessary” to respond to the threat and not last more than 6 months. In exceptional circumstances, internal border controls can be reintroduced for a maximum of two years.

Several members of the bloc have reintroduced temporary border controls in recent years. The full list of countries that currently have controls in place is available here.
