Area code 908

At the time of the split, 1.5 million access lines were served by the new area code.

On January 1, 1997, 908 was reduced to its western portion, forming area code 732 in the central-eastern region of New Jersey.

Middlesex County is largely 908 in South Plainfield and parts of Edison (particularly Inman Avenue and north of Oak Tree Road) and Piscataway (particularly the New Market area near Plainfield).

908 and the Delaware Valley's 856 are the only area codes in the state that have yet to be overlaid.

This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.
