Area code 920

North American telephone area code 920 covers much of eastern Wisconsin. It was created on July 26, 1997, in a split from area code 414. 414 formerly covered the entire eastern third of the state. 920 will eventually be overlaid with area code 274 to bring ten-digit dialing into the area, but 920 is not predicted to be exhausted until 2028.

Wisconsin area codes.

A mnemonic device many used for the new area code was to remember Green Bay Packer Reggie White's jersey number, 92, and add a zero.[1]
