Area code 713

Area code 713 serves Texas, including Houston, Houston Suburban and Spring (Central time). It has been in service since January 1, 1947 and shares its area with 281, 346, 621 and 832.

Numbers starting with 713 drew 2,881 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 557 complaints to the FCC since November 2023. The number on your screen can be faked, so a 713 number proves nothing about where a call came from.

Phone companies holding 713 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 43% 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.
