Area code 432 serves western Texas, covering cities such as Midland, Odessa, Alpine, and Pecos. It was established in 2003 from a split of area code 915 to provide more localized telecommunications services in the Permian Basin region. Known for oil and gas production, 432 includes some of the most energy-rich land in the United States. It also contains vast desert landscapes, ranching communities, and growing cities tied to the petroleum economy. The 432 area code supports both industrial growth and rural heritage in West Texas.
