Kansas originally had two area codes, 316 and 913, when the numbering system was established in 1947. It was not until thirty years later in 1997 that Kansas experienced sufficient growth in population and telephone use to need an additional area code. To meet this increase in demand there were two area code splits. The first split was in 1997 and the second was in 2001.
