The main area code, 214, was one of the original area codes established in October 1947. It originally covered the entire northeastern quadrant of Texas, from Fort Worth to the border with Arkansas and Louisiana. Given the rotary dialing technology of the time, the North American Numbering Plan Administrator wanted to keep the number of "clicks" to a minimum for densely populated areas. For this reason, Dallas-Fort Worth, which was well into a dramatic period of growth that continues to this day, was given an area code with seven clicks.
In 1954, most of Tarrant County was combined with much of the eastern portion of area code 915 to form area code 817. In 1990, the entire eastern portion was split off as area code 903.
