Area code 664

This article is about the North American Numbering Plan area code. For the Mexican area code, see Area code 664 (Mexico).

Area code 664 in the North American Numbering Plan covers Montserrat, a tiny British Overseas Territory in the Caribbean. The 664 telephone area code, standing for "MNI," was created during a split from the original 809 area code, which began permissive dialing 1 July 1996 and ended 1 June 1997.

A domestic call within Montserrat is seven digits. A call from another North American Numbering Plan country (such as the United States or Canada) requires 1-664- and the seven-digit phone number, in the same format as a domestic toll call.

At one time the small island of Montserrat was able to get by with only using four-digit phone numbers internally, as the first three digits after the former 809 area code were the same for everyone (664). As of May 2011, Montserrat has seven-digit numbers beginning with 236, 349, 410, 411, 412, 413, 415, 491, 492, 493, 494, 495, 496, 664, and 724.
