History of Area Code 340

Area code 340 was created in 1997 as a split from area code 809. Before that change, the U.S. Virgin Islands shared area code 809 with several Caribbean locations. The split gave the territory its own area code within the North American Numbering Plan.

Area code 340 has not been overlaid or split since it was introduced. The change reflected the growth of telephone service and the need for separate numbering resources in Caribbean NANP territories. The U.S. Virgin Islands continues to use 340 for all local geographic telephone numbers.
