Area code 414, Telephone prefix in Milwaukee, United States.
Area code 414 is a telephone prefix serving the Milwaukee region in Wisconsin. It covers Milwaukee County and portions of Waukesha County, where millions of people live and work.
This area code was introduced in 1947 as one of the original numbering plans for Wisconsin. It emerged from the North American Numbering System that organized telephone networks across the region.
The number sequence 414 has become part of Milwaukee's local identity. Residents use it daily in their daily lives, and the city established April 14th as Milwaukee Day to celebrate this connection.
Calls within this area code avoid long-distance charges between different locations. This makes it practical to stay in touch with people across the region without worrying about extra costs.
In the 1980s, a group of Milwaukee teenagers known as The 414s gained national attention by accessing computer systems across North America. This hacker group became the basis for strict laws against computer crimes.
