National identity cards are issued to their citizens by the governments of all European Union member states except Denmark, Ireland, the United Kingdom and Liechtenstein. Citizens holding a national identity card, which states EEA or Swiss citizenship, can use it as an identity document within their home country, and as a travel document to exercise the right of free movement in the EEA and Switzerland.[1] Identity cards that do not state EEA or Swiss citizenship, including national identity cards issued to residents who are not citizens, are not valid as a travel document within the EEA and Switzerland.
