Area code 346

Area code 346 serves Texas, including Houston, Houston Suburban and Bammel (Central time). It has been in service since July 1, 2014 and shares its area with 281, 621, 713 and 832.

Numbers starting with 346 drew 1,925 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 822 complaints to the FCC since November 2023. The number on your screen can be faked, so a 346 number proves nothing about where a call came from.

Phone companies holding 346 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.
