Area codes in the Caribbean

A map of the Caribbean, showing NANP area codes (black) and country codes of independent regions (red).

Of the above territories, the only one that was outside the NANP in 1995 was Sint Maarten, part of the Netherlands Antilles until dissolution in 2010 and now a constituent country within the Kingdom of the Netherlands. Sint Maarten used the country code +599 of the Netherlands Antilles until joining the NANP on September 30, 2011, with area code 721.[2]

The following was the 1958-1995 numbering plan for 809. 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 number pool of the area code was divided between the regions by the national number, which was from two to four digits long, leaving five to three digits, respectively, of the total of 10 digits of a complete telephone number for local telephone number assignments. The national number appeared in local telephone directories.

Caribbean nations with a larger numbering resource requirement used seven-digit dialing, and had no need for a national number.

Non-NANP jurisdictions (i.e., the rest of the world) identified a Caribbean calling destination by analyzing the first six digits dialed (1809xx), therefore, faced the difficulty where a seventh digit was required to identify the specific nation. Rates based on destination would have to be the same for all destinations sharing the same six digits, e.g., St. Lucia and St. Vincent would have to be the same rate; Anguilla, British Virgin Islands and Montserrat would need to be the same rate; Antigua, Barbuda, Nevis and St. Kitts also would have to be the same rate. Since Cable and Wireless was the provider in most or all cases, the same corporate entity benefited from the revenue for incoming calls. The assignment of new area codes after 1994 resolved this since only the first four digits would be required to distinguish each country.

In chart above, digits in italics were just the initial digit(s) of seven-digit number dialing.

Sint Maarten was part of +599 until long after 809 was totally divided into individual area codes.
