Area code 214 serves central Dallas and portions of its immediate suburbs in northern Texas. As one of the original area codes established in 1947, 214 once covered all of northeastern Texas before being split to form 903 and later overlaid with 972 and 469. Today, it is part of a complex overlay system that includes 972, 469, and 945, all serving the Dallas–Fort Worth metroplex. Known for finance, technology, and transportation, the Dallas area continues to expand rapidly. The 214 code remains a prestigious and highly sought-after number in the region.
