The area code 868 is assigned to

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]

History

Area code 868 ("TNT") was created during a split from the original

Area code 809 with permissive dialing beginning 1 June 1997.[6]
With the end of permissive dialing on 31 May 1998, all calls placed to the Republic of Trinidad and Tobago required the use of the +1 868 prefix.[6] The local telephone regulator proposed the area code 868, which corresponds to "TNT"—an abbreviation for Trinidad and Tobago—to reflect the nation's identity within the NANP.

Dialing to Trinidad and Tobago

  • From within North America (NANP)

When calling Trinidad and Tobago from elsewhere in the North American Numbering Plan (e.g., from the

phone number
.

  • From outside NANP

When calling to Trinidad and Tobago from outside the NANP (e.g., from the United Kingdom), callers must dial their international dialing prefix followed by 1 to access the North American Numbering Plan. For example, a call placed from the United Kingdom would be dialled as 00 + 1 + 868 + local seven digit phone number.

Dialing within Trinidad and Tobago

When placing a

phone call from Trinidad and Tobago, also known as HNPA (home numbering plan area) dialing, callers simply use seven-digit dialing
(i.e. dialing 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

phone number
.

Though usually toll-free when dialed from the US, not all 1-800 phone numbers are toll-free when dialed from Trinidad and Tobago, and may be treated as a toll call.

  • To areas outside the NANP

When calling to areas outside 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.
