The numbers shown above are area codes (city codes) within the North American zone, country code +1. For example, BS Bahamas = +1 242. Within North America, dial 1 plus the area code; from other countries, dial the international access prefix (e.g., 00) plus 1 plus the area code.
The map above is adapted (with permission) from North American Numbering Plan Planning Letter PL-NANP-038, dated 1997-01-23. This map is an approximation; it is not precisely to scale, and may not show the exact relative positions of the various islands. Although BM Bermuda is not in the Caribbean Sea, it is included here for historical reasons, since it was part of the old +1 809 area code.
Details about the Caribbean area codes and other nearby country codes are presented in table format on a separate web page. As of 1999-05-31, only DO Dominican Republic continues to use area code +1 809, now overlaid with +1 829 and +1 849. Note that PR Puerto Rico's +1 787 was overlaid with +1 939.
NEW! Sint Maarten, the Dutch side of the island of Saint Martin, will change from international country code +599 to North American area code +1 721 on 2010-05-31. Use either code until 2010-11-30, when area code 721 becomes mandatory. Saint Martin/Sint Maarten is not marked on the map, but is located immediately south of Anguilla.
