Area codes

340

Dialing the USVI from the mainland is a domestic call: 1 340 plus seven digits, no exit code, no trunk zero — the territory has sat inside the North American Numbering Plan on area code 340 since its 1997 split from the Caribbean 809. Islanders dial 011 to call outside the plan, just like any US state.

Ten NANP digits under area code 340, covering St. Thomas, St. John and St. Croix; seven digits locally.
