Geographic Coverage & Key Cities

The 832 area code spans Houston and its surrounding communities, encompassing eight counties: Harris, Brazoria, Chambers, Fort Bend, Galveston, Liberty, Montgomery, and Waller. Beyond Houston's city limits, it encompasses flourishing communities such as Sugar Land, The Woodlands, Pearland, Pasadena, and League City.

The 832 area code was introduced in 1997 as an overlay to the original 713 area code, which had served Houston and its environs since 1947. The overlay was implemented to address the rapid population growth and increasing demand for telephone numbers driven by the city’s expanding residential and business sectors. Later, the 281 area code was also introduced as an overlay, further expanding the region's numbering capacity.

Houston stands as America’s fourth-largest city and forms the center of one of the country’s most economically diverse regions. The 832 territory is home to global energy headquarters, with traditional oil and gas companies joined by expanding renewable energy sectors. The region also boasts the renowned Texas Medical Center, NASA’s Johnson Space Center, and the bustling Port of Houston. This unique economic blend creates diverse business opportunities, while Houston’s remarkable diversity, with residents speaking over 145 languages, provides natural connections to global markets.
