Area code 435

Area code 435 serves Utah, including Saint George, Logan and Park City (Mountain time). It has been in service since September 21, 1997.

Numbers starting with 435 drew 1,090 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 638 complaints to the FCC since November 2023. The number on your screen can be faked, so a 435 number proves nothing about where a call came from.

Phone companies holding 435 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 64% 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.
