Organisation of Eastern Caribbean States: Anguilla, Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines.
Six of the states using the EC$ are independent states: Antigua and Barbuda, Dominica, Grenada, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines. The other two are British overseas territories: Anguilla and Montserrat. The only OECS member state not using the Eastern Caribbean dollar is British Virgin Islands, which uses the U.S. dollar.
The combined population is close to 600,000 (2005 and 2006 census and estimates), which is comparable to Montenegro or the city of Washington, D.C..
Queen Elizabeth appears on the banknotes and the obverse of the coins: She is the head of state of all the states and territories using the EC$, except Dominica.
