Area code 432 covers west Texas, including Midland, Odessa, Alpine, and the Big Bend region. Created in 2003 from a split with area code 915, it serves a sparsely populated but economically vital area driven by the oil and gas industry. Midland and Odessa are energy hubs, while the rest of the region is known for desert landscapes, ranching, and national parks. Seven-digit dialing is still used in many places. Area code 432 stands for Texas grit, economic strength, and rugged independence, capturing the wide-open character of the Permian Basin and surrounding areas.
