[edit] History of area codes in Kansas
Despite a relatively small population, Kansas was scheduled to receive two area codes under the original North American Numbering Plan proposal from the Bell Telephone Company in 1946. Originally, area codes would follow sequentially based on geography, and under the 1946 plan, Kansas would receive area codes 617 and 618.(1)
In October 1947, the final plan was adopted, and Kansas still had its two area codes, although the numbers had been radically altered from the original plan. The southern half of the state (Dodge City, Emporia, Garden City, Wichita) would receive 316, while the northern half (Kansas City, Topeka, Lawrence, Salina, Hays) would receive 913. All long-distance calls using area codes would not be implemented until late in 1951.

The two area codes of Kansas remained constant for more than 40 years, but by the mid-1990s, the proliferation of cell phones, the population explosion in the Kansas City metropolitan area (most notably Johnson County), and deregulation due to the Telecommunications Act of 1996, the exchanges for area code 913 were quickly being exhasuted.
Late in 1996, the Kansas Corporation Commission, which oversees telecommunications in the state, requested relief from the NANPA for the exchanges of area code 913, and on February 12, 1997, the NAPNA responded by splitting off most of northern Kansas from area code 913 into the new 785 area code. From July 20, 1997 through October 2, 1998, a period of permissive dialing was in use, allowing customers affected by the new area code to use either 913 or 785 when dialing long-distance. At 12:01 a.m. on October 3, 1998, the 785 area code became mandatory in thew new calling area.
The southern half of the state would soon follow. With a similar proliferation of cell phones, especially in and around Wichita, the KCC requested relief for area code 316. On September 21, 2000, the NANPA announced relief by splitting off most of southern Kansas and giving it the new 620 area code. A period of permissive dialing was initiated on February 3, 2001, where numbers in the affected area could be dialed using 316 or 620. The use of 620 became mandatory on November 3, 2001.

[edit] Boundaries of area code 316
When most of area code 316 was moved to the new area code 620, all of Sedgwick County, as well as portions of Butler and Harvey counties remained in area code 316.
When area code 316 covered all of southern Kansas, the boundary ran from west to east roughly following a path along K-4 and K-96. The code boundary dipped along I-135 in McPherson County and continued east to just north of Emporia in Lyon County along the Kansas Turnpike, and ended at the Missouri state line.
With the area code now shrunk to a fraction of its former size, 316 is the only one of Kansas' four area codes that does not reach the Missouri border.
