Area code 785
Area code 785 is the area code for telephone exchanges in most of northern Kansas. It was created in a split of the numbering plan area 913 on July 20, 1997, and stretches from the Colorado state line on the west to the Missouri state line on the east, while excluding the Kansas side of the Kansas City metropolitan area, which retained 913. The largest city by population in the numbering plan area is the Kansas state capital, Topeka.
History of area codes in Kansas
When area codes were implemented in 1946, the southern half of the state (Dodge City, Emporia, Garden City, Wichita) was designated as numbering plan area 316, while the northern half (Kansas City, Topeka, Lawrence, Goodland, Manhattan, Salina, Hays) received area code 913.
This configuration remained in place for 40 years. However, by the mid-1990s, 913 was close to exhaustion due to the popularity of cell phones and pagers (especially in the Kansas City suburbs, Topeka, and Lawrence), as well as the rapid growth of the Kansas City area.
Late in 1996, the Kansas Corporation Commission, which oversees telecommunications in the state, requested relief from the North American Numbering Plan Administration (NANPA) for the exchanges of area code 913. On February 12, 1997, the NANPA announced a cut back to the Kansas side of the Kansas City area, while most of the western portion of the old 913 plan area was split off in a new plan area, with area code 785, effective on July 20, 1997. Permissive dialing continued until October 3, 1998.
The bulk of 785's landlines and cell phones are in the eastern portion, in and around Topeka and Lawrence. Despite this, 785 is nowhere near exhaustion. Under the most recent NANPA projections, it will remain in its present configuration for the foreseeable future.
The boundary between 785 and area code 620, which covers southern Kansas outside of the Wichita metropolitan area, runs from west to east roughly following a path along K-4 and K-96. The code boundary dips along I-135 in McPherson County and continues east to just north of Emporia in Lyon County along the Kansas Turnpike. At this point, area code 785 reaches its easternmost boundary with the current boundary for area code 913, although a small portion of the northeast corner of Kansas across the Missouri River from St. Joseph, Missouri is part of 785.
The numbering plan area contains the entire counties of Anderson, Cheyenne, Franklin, Rawlins, Decatur, Norton, Phillips, Smith, Jewell, Republic, Washington, Nemaha, Marshall, Brown, Sherman, Thomas, Sheridan, Graham, Rooks, Osborne, Mitchell, Lincoln, Cloud, Ottawa, Clay, Riley, Pottawatomie, Jackson, Wallace, Logan, Gove, Trego, Ness, Rush, Ellis, Russell, Ellsworth, Saline, Dickinson, Geary, Wabaunsee, Shawnee, Osage, and Douglas, as well as portions of Doniphan, Atchison, Coffey, Lyon, Jefferson, Morris and McPherson counties.
One exception to this rule is the city of Elwood, which retained the 913 area code while the rest of Doniphan County switched to 785. This is because Elwood's servicing wire center is in St. Joseph, Missouri, which is part of the Kansas City, Missouri LATA, located in area code 816. It would have been too expensive for Southwestern Bell to reroute Elwood's trunk lines so it could follow the rest of Doniphan County into 785. All bordering 816/913 rate centers have each other's area codes.
