North American telephone area code 262 covers much of Southeastern Wisconsin, and was created on September 25, 1999 when it was split from area code 414. It covers most of the suburbs of Milwaukee, but not Milwaukee County itself.
When it became apparent that 414 was running out of numbers, original plans called for 262 to be an overlay for all of southeastern Wisconsin. But overlays were a new concept at the time, and there was resistance to the mixing of area codes in the same area and the requirement for ten-digit dialing. As a result, 262 was made a separate area code for nearly all of the old 414 territory outside of Milwaukee County.
