Area code 848 is an overlay for area code 732 in central New Jersey, covering communities such as Edison, Toms River, New Brunswick, and Woodbridge. Introduced in 2001, the overlay was implemented to handle the growing demand for phone numbers in the populous corridor between New York City and Philadelphia. As an overlay, 848 requires ten-digit dialing and is commonly assigned to new mobile lines and businesses. The region is economically vibrant, with strong representation in pharmaceuticals, education, and telecommunications. While 732 retains legacy status, 848 plays a crucial role in modern connectivity throughout the area. It reflects the continued growth of central New Jersey’s suburban and coastal regions.
