Geographic Coverage & Key Cities

The 281 area code blankets most of the Houston metropolitan region, connecting you to communities like Katy, Sugar Land, The Woodlands, Humble, Pasadena, Pearland, Conroe, and Baytown. It stretches across eight counties: Harris, Fort Bend, Montgomery, Galveston, Chambers, Brazoria, Liberty, and Waller. This geographic area represents one of America’s most economically important urban regions, linking your business to sectors ranging from energy innovators to tech startups.

The 281 area code was created on November 2, 1996, as a split from Houston’s original 713 area code due to rapid regional growth and increasing demand for telephone numbers. Initially, 713 covered the entire Houston area since 1947. However, as the city expanded, 281 was introduced to serve the suburbs outside Beltway 8, while 713 remained for Houston proper and regions within the beltway.

However, the explosive growth in telecommunications led to the introduction of an overlay system in 1999, combining the 713 and 281 area codes with the new 832 area code across the same geographic region. This overlay system enables businesses to secure Houston phone numbers more easily, even in high-demand situations, providing room to grow as your business expands.

Together, these area codes form a robust numbering plan that supports Houston’s diverse and booming economy, from traditional energy sectors to emerging technology hubs.

Time Zone & Business Impact
