About Area Code 201
Area code 201 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the New Jersey region anchored on Jersey City.
201 now shares its territory with an overlay code (551). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 201 are portable: a person who moved away from Jersey City may still carry a 201 mobile number on their device. If you receive an unexpected call from a 201 number, run it through the reverse lookup tool above for the most accurate, free identification.
