Area code 559

Area code 559 serves California, including Fresno, Visalia and Clovis (Pacific time). It has been in service since November 14, 1998 and shares its area with 357.

Numbers starting with 559 drew 1,690 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 533 complaints to the FCC since November 2023. The number on your screen can be faked, so a 559 number proves nothing about where a call came from.

Phone companies holding 559 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 79% 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.
