Area code 856 is a telephone area code in the North American Numbering Plan (NANP) for the southwestern part of the U.S. state of New Jersey. The numbering plan area (NPA) includes the Camden, Cherry Hill, and Vineland areas and a small part of Willingboro Township and the western part of Burlington County. 856 is essentially coextensive with the New Jersey side of the Philadelphia metropolitan area.
The area code was created in 1999 in a split of area code 609. [1]
The entire state of New Jersey was assigned area code 201 in 1947, when the American Telephone and Telegraph Company (AT&T) established a nationwide telephone numbering plan for use in Operator Toll Dialing, which later developed into the North American Numbering plan. [2] The area code had its debut in customer-dialed communication in 1951, with the first trial of Direct Distance Dialing (DDD). [3]
In 1958, the administration divided the state into two numbering plan areas, restricting the use of 201 to the northern part, while the southern part of the state received area code 609. [4]
With the increasing demand for telephone numbers by businesses, increased used of fax machines, pagers and cell phones, area code 609 exhausted its numbering capacity. [5] Area code 856 was announced by Bell Atlantic in March 1999, and was approved by the New Jersey Board of Public Utilities shortly thereafter. The new area code became operational on June 12, 1999. A permissive dialing period of five months ended on November 13, 1999, during which seven-digit was still permitted.
Prior to October 2021, area code 856 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. [6]
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. Area code 557 was added to the 314 numbering plan area on August 12, 2022, to form an overlay numbering plan.
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.

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.
