The area code 868 is assigned to Trinidad and Tobago, a member of the North American Numbering Plan (NANP). The telephone numbering plan for the country is known as the National Numbering Plan.[1] It is part of a system used for assigning telephone numbers in Trinidad and Tobago, and functions as a part of the North American Numbering Plan (NANP). It is regulated by the Telecommunications Authority of Trinidad and Tobago, which holds responsibility for telecommunications in the country.[2]
Due to a long established affiliation with NANP,[3] phone numbers in the Republic of Trinidad and Tobago are often styled as "(868) NXX-xxxx". However, the International Telecommunications Union's standards such as E.164[4] and E.123 both strongly advocate the inclusion of a "+1" prefix to indicate "868" is a part of the NANP.[5]
