History of Area Code 340
Area code 340 entered service on June 1, 1997, after the U.S. Virgin Islands split from area code 809. Before that change, area code 809 served the territory as part of a broader Caribbean numbering area.
The 1997 split gave the U.S. Virgin Islands its own geographic North American Numbering Plan code. Area code 340 remains the territory's single area code, with no overlay or later area-code split assigned.
