Overview
Area code 913 is a telephone numbering plan area in the North American Numbering Plan. It serves the northeastern portion of the U.S. state of Kansas and is most closely associated with the Kansas side of the Kansas City metropolitan area. The code is part of the standard NPA-NXX-XXXX format used across the NANP; for context see North American Numbering Plan.
Coverage and major communities
Today 913 covers a compact, urban and suburban region in northeastern Kansas. Its service area includes key population centers and many suburbs that are economically and socially linked to Kansas City. Major cities and municipalities in the 913 territory include:
- Kansas City, Kansas
- Overland Park
- Shawnee
- Other communities in Johnson, Wyandotte, and Leavenworth counties
History and development
Area code 913 was one of the original area codes assigned when the NANP was implemented in 1947. Originally it covered a much larger portion of northern Kansas. As demand for telephone numbers grew — driven by population increases, business expansion, and the addition of mobile phones and other services — the numbering plan required changes. In 1997 much of the northern and western portion of the original 913 territory was split off to form area code 785, leaving 913 concentrated on the Kansas City area and its suburbs.
Function, dialing and notable facts
Like other NANP area codes, 913 provides the three-digit prefix that begins local telephone numbers. Calls within the area typically follow local or long-distance dialing rules set by carriers and regulators. The boundaries of 913 reflect telephone service needs rather than strict political lines, so some communities near the edge of the Kansas City metropolitan area may be served by neighboring codes.
