Montserrat Area Codes
Montserrat is currently using one area code. Montserrat does not utilize any area code overlays. Area code 664 was created from a split of area code 809.
Area code 809 originally covered most of the Caribbean when it was established in 1958. It was not until 1996 that an area code was established exclusively for Montserrat. Since Montserrat previously shared area code 809 with other Caribbean nations the establishment of area code 664 was technically a split of area code 809.
