Area code 284

Area code 284 is the telephone area code in the North American Numbering Plan (NANP) for the British Virgin Islands (BVI). The numbering plan area (NPA) was created in a split of the Caribbean numbering plan area (area code 809) on 1 October 1997. A permissive dialing period, during which the old area code could still be dialed, ended on 30 September 1998. Existing central office codes and line numbers were unaffected by the change of area code. New exchanges established after the in-service date, were required to be dialed with the new area code. The digit sequence 284 spells BVI on the alphanumeric telephone keypad. Within the British Virgin Islands, the seven digits are dialed for local calls. For calls from other NANP countries to the British Virgin Islands, the dialing sequence is 1 NPA-XXX-XXXX, where 1 is the NANP trunk access code.
