Area code 214 serves Dallas and its surrounding suburbs in north-central Texas. It was one of the first area codes created in 1947 and now operates in an overlay with 469, 972, and 945, necessitating ten-digit dialing. Dallas is a major hub for commerce, telecommunications, and finance, and 214 carries significant weight in these sectors. Despite multiple overlays, 214 remains a primary identifier for long-standing institutions and residents within the Dallas-Fort Worth Metroplex. The code reflects both legacy and modern growth in one of the fastest-growing regions in the U.S.
