What is what area code is 847?

Area code 847 is located in the northeastern part of Illinois and covers the northern suburbs of Chicago, including towns such as Arlington Heights, Des Plaines, Evanston, Glenview, and Skokie. The area code was created in 1996 when it split off from area code 708. At the time, the split was necessary due to the increasing demand for phone numbers in the region. Area code 847 is currently overlaid with area code 224, meaning that both area codes cover the same geographic area, and new phone numbers can be assigned with either area code.
