Area code 262 is a telephone area code in the North American Numbering Plan for the southeastern part of the U.S. state of Wisconsin. The numbering plan area comprises suburbs that are a part of the Milwaukee and Chicago metropolitan areas. The area code was created on September 25, 1999, in an area code split of area code 414.
The eastern portion of Wisconsin had been served by area code 414 for half a century until the Green Bay and the Fox River Valley were designated a new numbering plan area (NPA) with area code 920 in 1997, to provide more telephone numbers in the densest populated area of Milwaukee County. Although this was intended as a long-term solution, within a year 414 was again approaching exhaustion due to the continued proliferation of cell phones and pagers. The original mitigation plans called for 262 to be added as an overlay code for all of southeastern Wisconsin. However, overlays were a new concept at the time, and met with some resistance to the mixing of area codes in the same area and the ensuing requirement for ten-digit dialing. As a result, 262 was designated for a separate numbering plan area with nearly all of the territory outside Milwaukee County. A few slivers of Waukesha and Washington counties stayed in 414.
Projections in early 2019 suggested the Milwaukee suburbs would not need another area code until 2044 at the earliest, but later in 2019 no exhaust date was listed, meaning the date is 30 years or more in the future. [1]
Prior to October 2021, area code 262 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021. [2]
The area code serves the following six counties:
These counties include the municipalities of
Area codes 314 and 557 are telephone area codes in the North American Numbering Plan (NANP) in the U.S. state of Missouri, serving St. Louis and most of its inner-ring suburbs in neighboring St. Louis County. The numbering plan area is bordered to the west by area code 636, which serves St. Louis' outer suburbs to the west, south, and north. Across the Mississippi River to the east, 314 is adjacent to area code 618, which serves southern Illinois and most of Metro East.

Ten-digit dialing is a telephone dialing procedure in the countries and territories that are members of the North American Numbering Plan (NANP). It is the practice of including the area code of a telephone number when dialing to initiate a telephone call. When necessary, the ten-digit number may be prefixed with the trunk code 1, which is referred to as 1+10-digit dialing or national format.
Area codes 561 and 728 are telephone area codes in the North American Numbering Plan (NANP) for Palm Beach County in the U.S. state of Florida. 561 was created on May 13, 1996, in a split of area code 407. The numbering plan area (NPA) comprises nearly every major city in the county, the largest of which being West Palm Beach, Boca Raton, Wellington, Boynton Beach, Jupiter, Delray Beach, and Belle Glade. On March 10, 2023, area code 728 was added to the same numbering plan area to form an all-services distributed overlay.
The Milwaukee metropolitan area is a major metropolitan area located in Southeastern Wisconsin, consisting of the city of Milwaukee and some of the surrounding area.

It is the largest metropolitan area in Wisconsin, and the 39th largest metropolitan area in the United States.
Area codes 920 and 274 are telephone area codes in the North American Numbering Plan (NANP) for a large area of eastern Wisconsin. Area code 920 was created on July 26, 1997, in a split of area code 414, one of the original North American area codes of 1947. 274 was added to the same numbering plan area (NPA) on May 5, 2023 to create an area code overlay.

Area code 804 is the telephone area code in the North American Numbering Plan (NANP) for the east-central portion of Virginia. The numbering plan area is anchored by Virginia's capital, Richmond, and includes most of its metropolitan area. Other communities included are Chesterfield, Henrico, Hopewell, Mechanicsville, Powhatan, Midlothian, Petersburg, and Colonial Heights. This also includes the Northern Neck and the Middle Peninsula.

Area code 608 is a telephone area code in the North American Numbering Plan for much of southwestern Wisconsin, including the state capital city Madison. The area code was assigned in 1955 to a numbering plan area created from areas with area code 414 and area code 715, and was the third area code created in Wisconsin. Rapid growth of the area, specifically in Dane County, has brought the area code close to exhaustion of central office prefixes, with NANPA projections in 2022 projecting the need for relief by late 2023. In September 2022, the Wisconsin Public Service Commission and North American Numbering Plan Administrator (NANPA) announced an overlay complex for the numbering plan area with new area code 353, with an in-service date of September 15, 2023. New central office code orders were accepted starting on July 11, 2023, but can only be activated once all 608 central office codes are assigned.
