551 entered service when Northern New Jersey demand for numbers outgrew the 201 supply. Today it sits side by side with 201 across the same neighborhoods, used by newer businesses, mobile lines, and second numbers issued after the older code filled. The two codes route identically, though 201 still carries the older brand weight.
