Barbados is a member of the North America Numbering Plan ("NAMP"), and therefore shares the same dialling code as the United States (+1). The area code assigned to Barbados is 246.
A phone number in the NAMP consists of a three-digit area code, a three-digit central office code and a four-digit station number. For example: +1 (246) 000-1234
In the example above, +1 represents the country code. (246) represents the area code, 000 represents the central office code and 1234 represents the station number.
