Dialling Within Trinidad and Tobago
When placing a phone call from Trinidad and Tobago, also known as HNPA (home numbering plan area) dialling, callers simply use seven-digit dialling (i.e. dialling the last seven digits of the phone number).

- To North America (NANP)
When calling other places in the North American Numbering Plan, callers dial as if undertaking regular ten-digit dialling in those countries. Callers dial 1 + NPA area code + seven digit phone number.
Though usually toll-free when dialled from the US, not all 1-800 phone numbers are toll-free when dialled from Trinidad and Tobago, and may be treated as a toll call.

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