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 (usually 00) plus 1 plus the area code.
The map above is adapted (with permission) from Bellcore's North American Numbering Plan Planning Letter PL-NANP-038 [now available on the Neustar NANPA web site], dated 1997-01-23. (Bellcore administered the NANP until 1998-01-19, when Lockheed-Martin took over the contract. The NANP is now administered by Neustar NANPA, and Bellcore has changed its name to Telcordia.) 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, effective 2005-08-01. Note that PR Puerto Rico's +1 787 was overlaid with the new +1 939 area code, effective 2001-09-15.
