Area code 817 serves Fort Worth and the western side of the Dallas–Fort Worth metroplex in Texas. Introduced in 1953 from a split with 214, the area now includes overlays 682 and 945, requiring ten-digit dialing. Fort Worth is known for its blend of cowboy heritage and modern industries, including aerospace, healthcare, and finance. The 817 area code is a cornerstone of Tarrant County identity and is often used to distinguish Fort Worth from its larger neighbor, Dallas. It is a symbol of Western character, Texas pride, and metropolitan growth.
