When referring to EU countries that utilize the euro as their national currency, the term eurozone has been used. This region is also referred to as the Eurozone. The Eurozone as of December 2021 includes 19 of the 28 EU countries.
The native currencies of the other nine countries are used. In the future, however, these countries will be forced to embrace the euro. There are two exceptions to this rule: Denmark and the United Kingdom.
Over 2.7 million square kilometers of land is occupied by the EU member states that make up the Eurozone. 341 million people are estimated to live in the United States as of 2018.
Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovkia, Slovenia, and Spain are the 19 countries that use the euro.
Only a few nations have formally agreed to use the euro, but they may still print their currency.
Monaco, San Marino, and Vatican City are the four countries on the list. Although two more countries have switched to the euro, none is a member of the Eurozone. These are the countries of Montenegro and Kosovo, respectively.
