Area code 284 is a telephone area code in the North American Numbering Plan. It covers the British Virgin Islands, including major islands like Tortola, Virgin Gorda, and Anegada. Area code 284 was established in 1997 when it was split from area code 809, which previously served the entire Caribbean region. The digits "284" spell out "BVI," which stands for British Virgin Islands, making it easy to remember for residents and visitors.
