North American telephone area code 414 is a state of Wisconsin area code which was created along with area code 715 as one of the two original area codes assigned to Wisconsin in October 1947. Currently, the 414 area code is nearly exclusive to Milwaukee County, including the city of Milwaukee. However, a few small portions of Muskego and Brookfield, in Waukesha County, are also part of this area code.
The 414 area code originally covered all of eastern and southern Wisconsin, with 715 covering the north and west. The first split from the original 414 occurred in 1955, when much of the western portion was split off to form the 608 area code. The 414 was split again on July 26, 1997, when the northern half became the 920 area code. The current 414 area code was formed on September 25, 1999 by switching nearly all of its territory outside Milwaukee County to the 262 area code.
The area code gained infamy in 1983, when a gang of six Milwaukee-area teenagers calling themselves The 414s broke into several high-profile computer systems across the United States and Canada.
