In 1998, area code 262 was assigned as a second area code for southeastern Wisconsin due to the near exhaustion of area code 414. Initially, it was proposed as an overlay, but it was implemented as a geographic split in 1999, with most of the old 414 territory outside of Milwaukee County transferring to 262. Prior to October 2021, area code 414 had telephone numbers assigned for the central office code 988 . This area code transitioned to ten-digit dialing by October 24, 2021.
Area code 414 is a general purpose code which was placed in service on January 1, 1947.
