[3] As a member of the North American Numbering Plan, Barbados uses telephone country code 1 for inbound routing of international calls.
When calling Barbados from elsewhere in the North American Numbering Plan (e.g. from the United States or Canada), callers use ten-digit dialing after the long-distance trunk prefix 1.
When calling to Barbados from outside the NANP (e.g. from the United Kingdom), callers must dial the international dialling prefix followed by 1 to access the North American Numbering Plan.
When calling to areas outside the NANP (e.g. the United Kingdom), callers dial 011 + country code + telephone number.
[6][8] Following liberalisation of the telecommunications industry in Barbados, various central office codes were implemented for local mobile carriers.
[9] In most cases Barbados numbers beginning with the following central office codes do not permit incoming collect calls.
