The 847 area code is an area code of the North American Numbering Plan used in the state of Illinois. It was activated in 1996 and covers the northern suburbs of Chicago, including Evanston, Arlington Heights, and Skokie. It serves Cook, Lake, and McHenry counties and parts of Kane and DuPage counties.
The North American Numbering Plan consists of an area code and a prefix number. The area code divides districts in a geographic area into distinct areas of service. Each area code contains a maximum of 7.92 million numbers and can easily identify where a caller is located. This allows for efficient routing of incoming calls to the correct center. The area code for 847 was assigned by the Federal Communications Commission and meant to relieve the existing 312 and 708 area codes in the Chicago area.
