History of the 920 Area Code

The 920 area code was established in 1997 as a result of a split from the 414 area code. This change was necessitated by the increasing demand for telephone numbers in the region, driven by population growth and the proliferation of mobile devices. The area code has not undergone any further splits or overlays since its inception. In 2023, area code 274 was created and is currently an overlay to 920. For more historical details, consult the North American Numbering Plan Administrator (NANPA).
