The United States Minor Outlying Islands are a statistical designation defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM. The minor outlying islands and groups of islands consist of eight United States insular areas in the Pacific Ocean and one in the Caribbean Sea. The United States has a related territorial dispute with Colombia over administration of the Bajo Nuevo Bank and Serranilla Bank. These islands are not included in the ISO designation.(Wikipedia)
