The euro is the official currency of 20 of the 27 member states of the European Union. This group of states is officially known as the euro area or, more commonly, the eurozone. The euro is divided into 100 euro cents.

The euro sign is the currency sign used for the euro, the official currency of the eurozone and adopted, although not required to, by Kosovo and Montenegro. The design was presented to the public by the European Commission on 12 December 1996. It consists of a stylized letter E, crossed by two lines instead of one. Depending on convention in each nation, the symbol can either precede the value, or follow the value, often with an intervening space.
