Grenada is currently using one area code. Grenada does not utilize any area code overlays. Area code 473 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 1995 that an area code was established exclusively for Grenada. Since Grenada previously shared area code 809 with other Caribbean nations the establishment of area code 473 was technically a split of area code 809.
