Find any 664- phone number in Montserrat
The Montserrat area code 664 is part of the international telecommunications system known as the North American Numbering Plan. The plan establishes a three-digit area code for each specific geographic region around the world, including for the island of Montserrat in the Caribbean. All 10-digit phone numbers in Montserrat must begin with the area code 664 and are formatted as "664-XXX-XXXX".
This area code is also known as an ‘overlay’ code, meaning it is used to provide additional phone numbers for an area that is already served by an existing area code. In this case, 664 was added in 2011 on top of the existing area code, 464. 664 was chosen as the new area code to designate the additional phone numbers needed due to the large influx of cell phone users.
