The 713 area code, an integral part of the North American Numbering Plan, holds significant relevance in the telecommunications landscape of Texas, USA. Geographical Coverage and Major City: The 713 area code is located in the state of Texas, with its largest city being Houston. This area code primarily serves the southeastern part of Texas, spanning from the Sabine River to the Brazos Valley​​​​. History and Development: Area code 713 has a rich history dating back to January 1, 1947, when it was officially put into service. It has undergone several changes over the years. In 1982, the 713 area code was split to form area code 409. Further splits occurred in 1996 to create area code 281, and in 1999, area codes 713 and 281 were recombined and overlaid with area code 832. Additionally, area code 346 was introduced on July 1, 2014, as part of this area code overlay complex​​​​. Population Coverage and Overlays: As of the latest data, the 713 area code, along with its overlays (281, 346, 832), serves a significant population of approximately 6.57 million people. These overlays are part of a complex system designed to serve the same geographic area, ensuring adequate numbering resources for the region's growing telecommunications needs​​. In conclusion, the 713 area code is not only a key component of Texas' communication infrastructure but also a testament to the evolving nature of area code allocation and management. It plays a vital role in connecting millions of people in the Houston area and its environs, adapting to the region's expanding telecommunication demands.
