About the 551 area code
Area code 551 covers Jersey City, New Jersey, together with Hackensack, Bayonne, Union City, and Fort Lee, all on Eastern time (GMT -5).
It went into service in 2001 as an overlay of area code 201, the two codes occupying a single territory instead of separate ones. Dialing locally anywhere in that shared footprint means entering the full ten-digit number, area code first.
Dialing note: 551 is part of an overlay complex with 201, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
