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.
