Area codes in the Caribbean
From 1958 to about 1995, most of the British West Indies in the Caribbean Basin plus Bermuda, the U.S. Virgin Islands, the Dominican Republic and Puerto Rico shared a single area code 809 in the North American Numbering Plan. By the mid-1990s, with the advent and growth of fax machines, mobile phones, computers, and pagers in the region, the entire 809 block of seven-digit numbers was almost completely allocated. New area codes were added, and since 1999 no two territories share a code; 809 is now used only in the Dominican Republic.
Of the above territories, the only one that was outside the NANP in 1995 was Sint Maarten, part of the Netherlands Antilles until that entity's dissolution in 2010 and now a constituent country within the Kingdom of the Netherlands. Sint Maarten used the Netherlands Antilles country code of +599 until joining the NANP on September 30, 2011 with area code 721.
Former assignments within 809
The following was the 1994-1995 (809) numbering plan. Starting in the 1980s, Puerto Rico, Bermuda and the Dominican Republic began to use prefixes from unused ranges throughout the 2xx to 9xx range. Historic (1960s-mid-1980s) ranges are shown in parentheses.
The "National Number", referred to in the table below, appeared in local telephone directories. It is essentially an area code within an area code, bridging the gap between the seven-digit NANP standard and the local number length of four or five (or three in the case of Anguilla) digits. The National Number could also be thought of as a nationwide central office code, similar to a section of New York City having all of the 68X-XXXX numbers (or MUrray Hill numbers before the change to all-number calling).
Caribbean nations with a larger numbering resource requirement used seven-digit dialing, and had no need for a "National Number".
