Houston and the 713 core
In Houston, 713 is the code of the central city: Downtown, Midtown, Montrose, the Heights, the Texas Medical Center and the neighborhoods toward the Ship Channel. Suburbs such as Spring, Sugar Land and Baytown show up only with a handful of 713 exchanges, because they mostly received 281 and 832 numbers as the metro expanded.
