History of Area Code 414
Area code 414 was created in 1947 as one of the original North American area codes. At that time, it served a much larger part of Wisconsin than it does today. It was one of the first codes assigned when AT&T and the Bell System launched the North American Numbering Plan.
Area code 414 later shrank through splits as demand for phone numbers grew. In 1997, area code 920 split from 414. In 1999, area code 262 split from 414, leaving 414 mostly limited to Milwaukee County. In 2023, Wisconsin regulators approved an all-services overlay with area code 274, and 10-digit dialing became required in the 414 region on October 24, 2023.
