To Barbados

• From within North America (NANP)

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. Thus callers dial 1 246 and the seven digit local telephone number.

• From outside the NANP

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. For example, a call placed from the United Kingdom is dialled as 00 1 246 NXX XXXX, where NXX XXXX is the local telephone number.

Within Barbados

When placing a call within Barbados, callers use seven-digit dialling (i.e. dialling the last seven digits of the national telephone number). Unlike in some other Caribbean islands, most residential landline subscribers have unlimited/un-metered rates for calling other local landlines.

• To North America (NANP)

When calling to other places in the North American Numbering Plan, calls are dialed by ten-digit dialing in those countries. Callers dial 1 NPA NXX XXXX.

Though usually toll-free when dialled from the US, not all 1-800, 1-888, 1-877, or 1-866 are toll-free when being dialled from Barbados, and may be treated as a toll call.^{[citation needed]} If the number is not toll-free a recording gives directions for placing a fee based call.

• To areas outside the NANP

When calling to areas outside the NANP (e.g. the United Kingdom), callers dial 011 + country code + telephone number. In the case of the UK, a user dials 011 44 + area code + telephone number.

Following liberalisation of the telecommunications industry in Barbados, various central office codes were implemented for local mobile carriers.
