Area code 832 is an overlay for the greater Houston area, covering the same region as 713 and 281, including downtown Houston and suburbs like Sugar Land, Pasadena, and Pearland. Introduced in 1999, it was added to meet the demand for new numbers in one of the country’s fastest-growing urban centers. Ten-digit dialing is required for all calls in the overlay region. 832 is widely used for mobile phones, business lines, and new developments. It’s a vital part of Houston’s booming tech, energy, and healthcare sectors, and continues to support rapid expansion across Southeast Texas.
