Edison, NJ utilizes an area code overlay in which area codes 732 and 848 serve the same geographic area. The area code overlay which is in use today was established in 2001 at which time area code 848 was created as an overlay of area code 732. Ten digit dialing (area code + seven digit number) is necessary in Brick because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
In addition to Edison, NJ area codes 732 and 848 serve east central New Jersey including the larger communities of Brick, Carteret, East Brunswick, Edison, Freehold, Lakewood, Long Branch, Neptune, New Brunswick, North Brunswick, North Plainfield, Old Bridge, Perth Amboy, Rahway, Sayreville, Somerset, Toms River and Woodbridge, in addition to many smaller communities within the service area.
