North American Numbering Pla

Integrated telephone numbering plan serving 20 North American countries (Source: en.wikipedia.org)

Before 1995, all NANP countries and territories outside the contiguous United States, Alaska, Hawaii and Canada shared the area code 809. This included Puerto Rico and the U.S. Virgin Islands. Each has since been assigned one or more distinct numbering plan areas; area code 809 now exclusively serves the Dominican Republic (along with area codes 829 and 849). The United States Pacific territories of the Northern Mariana Islands and Guam joined the NANP in 1997, and American Samoa became an NANP member in October 2004. The Dutch possession of Sint Maarten was originally scheduled to join the NANP on May 31, 2010, but the changeover was postponed to September 30, 2011. (Source: en.wikipedia.org)
