You can use your European Health Insurance Card (EHIC) when you visit a country in the European Economic Area (EEA) or Switzerland if, for example, you are going on a holiday or business trip.
For a country-by-country guide, see travelling in the EEA and Switzerland.
You can't use your EHIC if you're moving abroad to live, work or study or going abroad for planned treatment (including giving birth). You also can't use your EHIC for private medical treatment.
The UK has agreements with some countries outside the EEA to provide healthcare for visitors. You do not need an EHIC to get urgent medical treatment in these countries, but you will usually need to provide documents that prove you live in the UK (such as a passport or driving licence).
