Area code 959

Area code 959 serves Connecticut, including Hartford, New Britain and New London (Eastern time). It has been in service since August 30, 2014 and shares its area with 860.

Numbers starting with 959 drew 635 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 301 complaints to the FCC since November 2023. The number on your screen can be faked, so a 959 number proves nothing about where a call came from.

Phone companies holding 959 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
