Area code 340

Area code 340 serves U.S. Virgin Islands, including Chtamstths, Chnstdstcr and St Croix (Atlantic time). It has been in service since June 1, 1997.

Numbers starting with 340 drew 12 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 5 complaints to the FCC since November 2023. The number on your screen can be faked, so a 340 number proves nothing about where a call came from.

Phone companies holding 340 exchanges
