Is area code 713 a scam?
No. Area code 713 is a legitimate area code serving Houston since 1947. Scammers spoof caller ID to display 713 numbers, which is why complaints exist against a code that is itself genuine.
Neighbour spoofing is the reason a local-looking number is not a guarantee. A caller anywhere in the world can display a 713 number, and the number they display may belong to a real business in Houston that has nothing to do with the call.

Why am I getting text messages from area code 713?
Texts from 713 numbers follow the same pattern as calls — mostly local businesses and services. Treat any text asking for payment or credentials as suspect regardless of the code.
The common patterns are a wrong-number opener that turns into conversation, an unsolicited job offer, and a crypto or investment tip. Do not reply, do not follow the link, and forward the message to 7726 (SPAM) to report it to your carrier.

Area codes that overlay 713
Area code 713 shares its geographic footprint with 2 other codes: 346, 832. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Area code 713 is the original Houston code, in service since 1947, and it still signals the city's core more than its newer overlays 832 and 346. Houston is the energy capital of the United States. ExxonMobil, Chevron, Shell, ConocoPhillips, and a deep bench of oilfield services firms like Halliburton, SLB, and Baker Hughes run major operations here, and the Houston Ship Channel handles one of the largest port complexes in the country. The city is also home to the Texas Medical Center, the largest medical complex in the world, and to NASA's Johnson Space Center, which anchors an aerospace cluster on the southeast side. Houston had 2.33 million residents and an employed population of 1.15 million in 2024 (DataUSA).
Who lives in the 713 region
The customer base behind a 713 number is young, international, and enormous. Median age in Houston was 34.4 in 2024, 29.2 percent of residents were born outside the country, and 44.2 percent of the population is Hispanic (DataUSA, 2024). Median household income was $64,813, with a poverty rate of 19.9 percent, so the metro spans everything from energy-executive wealth to working-class neighborhoods in the same dialing area. Spanish-language capability is a practical requirement for consumer-facing businesses across much of the city.
What a 713 number signals to a caller
Business in Houston moves fast and deals get done over the phone more than outsiders expect. Callers describe a culture that is friendly on the surface but transactional underneath, a place where relationships matter in energy and real estate but nobody wastes time on ceremony. The city runs on Central Time, and calling windows for energy-sector offices tend to start early. Because 713, 832, and 346 all overlay the same territory, locals dial ten digits by habit and treat all three as Houston, but a 713 prefix still carries a hint of legacy status with longtime residents of Texas.
Area code 713 serves Houston and surrounding communities in Texas. It is in the Central Time zone.

Why am I getting calls from 713?
Calls displaying a 713 number come from businesses and individuals in the Houston area, and from anywhere at all when caller ID is spoofed to look local. 1,117 713 numbers were reported to the FTC in the 30 days to 8 October 2026.
How do I block calls from area code 713?
