Who works in the Houston area?

Houston is the energy capital of the western hemisphere, and area code 346 covers all of it. The code arrived in 2014 as the third overlay on the 713 territory, added because the city's growth kept exhausting numbers. The industries doing that growing are oil and gas majors and the engineering firms that serve them, the Texas Medical Center, which is the largest medical complex in the world, the Port of Houston, and NASA's Johnson Space Center. ExxonMobil, Chevron's relocated headquarters, and dozens of midstream and oilfield services companies run their operations from the metro.

What a 346 number signals to a caller
