1 These countries are currently not participating in the EU's single market (EEA), but the EU has common external Customs Union agreements with Turkey (EU-Turkey Customs Union in force since 1995), Andorra (since 1991) and San Marino (since 2002). Monaco participates in the EU customs union through its relationship with France; its ports are administered by the French. Vatican City has a customs union in effect with Italy.
2 Andorra, Monaco, San Marino and Vatican City are not members of Schengen, but act as such via their open borders with Spain, France and Italy, respectively.
3 Switzerland is not an official member of EEA but has bilateral agreements largely with the same content, making it virtually a member.
4 Andorra, Monaco, San Marino and Vatican City are using the euro as their currency through a monetary agreement with the EU.
5 Montenegro and Kosovo unilaterally adopted the euro as their currency and, therefore, have no issuing rights.
6 Currency included in the ERM II mechanism.
The European Free Trade Association (EFTA) is a regional trade organization and free trade area consisting of four European states: Iceland, Liechtenstein, Norway and Switzerland. The organization operates in parallel with the European Union (EU), and all four member states participate in the European single market and are part of the Schengen Area. They are not, however, party to the European Union Customs Union.
The euro area, commonly called the eurozone (EZ), is a currency union of 20 member states of the European Union (EU) that have adopted the euro (€) as their primary currency and sole legal tender, and have thus fully implemented EMU policies.
The European Union has a number of relationships with foreign states. According to the European Union's official site, and a statement by Commissioner Günter Verheugen, the aim is to have a ring of countries, sharing EU's democratic ideals and joining them in further integration without necessarily becoming full member states.
Europe is often divided into regions and subregions based on geographical, cultural or historical factors. Since there is no universal agreement on Europe's regional composition, the placement of individual countries may vary based on criteria being used. For instance, the Balkans is a distinct geographical region within Europe, but individual countries may alternatively be grouped into South-eastern Europe or Southern Europe.
European integration is the process of industrial, economic, political, legal, social, and cultural integration of states wholly or partially in Europe, or nearby. European integration has primarily but not exclusively come about through the European Union and its policies.
A customs union is the principal area of robust formal agreement between the Principality of Andorra and the European Union (EU). Andorra borders two EU member states: France and Spain.
Currently, all of the European microstates have some form of relations with the European Union (EU).
The Citizens' Rights Directive 2004/38/EC sets out the conditions for the exercise of the right of free movement for citizens of countries in the European Economic Area (EEA), which includes the member states of the European Union (EU) and the three European Free Trade Association (EFTA) members Iceland, Norway and Liechtenstein. Switzerland, which is a member of EFTA but not of the EEA, is not bound by the Directive but rather has a separate multilateral sectoral agreement on free movement with the EU and its member states.
Liechtenstein passports are issued to nationals of Liechtenstein for the purpose of international travel. Beside serving as proof of Liechtenstein citizenship, they facilitate the process of securing assistance from Liechtenstein consular officials abroad.

3 Switzerland is not an official member of EEA but has bilateral agreements largely with same content, making it virtual member.
The Schengen Area is an area encompassing 29 European countries that have officially abolished border controls at their mutual borders. Being an element within the wider area of freedom, security and justice policy of the European Union (EU), it mostly functions as a single jurisdiction under a common visa policy for international travel purposes. The area is named after the 1985 Schengen Agreement and the 1990 Schengen Convention, both signed in Schengen, Luxembourg.
The international status and usage of the euro has grown since its launch in 1999. When the euro formally replaced 12 currencies on 1 January 2002, it inherited their use in territories such as Montenegro and replaced minor currencies tied to pre-euro currencies, such as in Monaco. Four small states have been given a formal right to use the euro, and to mint their own coins, but all other usage outside the eurozone has been unofficial. With or without an agreement, these countries, unlike those in the eurozone, do not participate in the European Central Bank or the Eurogroup.
Relations between the Republic of San Marino and the European Union (EU) began in February 1983. San Marino is completely surrounded by one EU member state, Italy.
Relations between the Principality of Monaco and the European Union (EU) are primarily conducted through France. Through that relationship Monaco directly participates in certain EU policies. Monaco is an integral part of the EU customs territory and VAT area, and therefore applies most measures on excise duties and VAT. Monaco borders one EU member state: France. However this relationship does not extend to external trade. Preferential trade agreements between the EU and third countries apply only to goods originating from the customs territory – Monaco may not claim EU origin in this respect.
National identity cards are identity documents issued to citizens of most European Union and European Economic Area (EEA) member states, with the exception of Denmark and Ireland. As a new common identity card model harmonized the various formats in use from 2 August 2021, with older ID cards currently being phased out according to EU Regulation 2019/1157.
The European Travel Information and Authorisation System (ETIAS) is a planned electronic authorisation system of the European Union for visa-exempt visitors travelling to the Schengen Area, as well as Cyprus. ETIAS is planned to cost €7 for applicants between ages 18 and 70, and to remain valid for three years or until the expiry date of the passport, whichever is sooner. As of November 2024, ETIAS is planned to come into force six months after the EU Entry/Exit System, a system for electronically registering travellers' border crossings, which was planned for May 2025.
The United Kingdom (UK) was a member of the European Economic Area (EEA) from 1 January 1994 to 31 December 2020, following the coming into force of the 1992 EEA Agreement. Membership of the EEA is a consequence of membership of the European Union (EU). The UK ceased to be a Contracting Party to the EEA Agreement after its withdrawal from the EU on 31 January 2020, as it was a member of the EEA by virtue of its EU membership, but retained EEA rights during the Brexit transition period, based on Article 126 of the withdrawal agreement between the EU and the UK. During the transition period, which ended on 31 December 2020, the UK and EU negotiated their future relationship.
Passports of the EFTA member states are passports issued by the European Free Trade Association (EFTA) member states Iceland, Liechtenstein, Norway and Switzerland. EFTA is in this article used as a common name for these countries.
Passports in Europe are issued by each state individually, e.g. the Netherlands or United Kingdom. In general, passports issued in Europe either grant the holder the right of freedom of movement within the European Economic Area, to those that don't. The majority of European states are members of the European Union, and therefore issue EU passports.
