North Jersey - Two-portion Approaches

Two-portion Approaches

Some define North Jersey as all points in New Jersey north of I-295 in the western part of the state and all points north of I-195 in the eastern part of the state. Others define it using the two original telephone area codes- 201 and all its additions for north and 609 (today plus 856) for south.

Others, primarily those who live in the northern tier of counties, count only that area north of the mouth of the Raritan River.
