Since the establishment of sovereignty with the ratification of the Constitution in 1993, Andorra has moved to become an active member of the international community. In July 1993, Andorra established its first diplomatic mission, opening a mission at the United Nations. In early 1995, the United States and Andorra established formal diplomatic relations. Andorra also has extended relations to other nations.

Andorra is a full member of the United Nations, including the UN Educational, Scientific and Cultural Organization (UNESCO) and the UN Conference for Commerce and Development (UNCCD); International Center of Studies for Preservation and Restoration of Cultural Heritage (ICCROM); International Telecommunications Union (ITU); International Red Cross; Universal Copyright Convention; European Council; European Union Telecommunications and Satellite (EUTELSAT); World Tourism Organization; Organization for Security and Cooperation in Europe (OSCE); Customs Cooperation Council (CCC); Interpol; and International Monetary Fund, among others.
