Area code 848 is an overlay for 732, covering central New Jersey, including cities such as New Brunswick, Toms River, Edison, and Woodbridge. Introduced in 2001, the area code was created to accommodate the population and telecommunications growth in this highly developed corridor. The region includes a mix of suburban neighborhoods, coastal communities, and industrial zones. Ten-digit dialing is required. While 732 is more widely recognized, 848 is frequently used for new lines and represents the ongoing expansion and density of one of New Jersey’s most important regions.
