201 Area Code: Jersey City, New Jersey

The 201 area code is the original area code of New Jersey and now serves the state's northeastern corner across from New York City. Jersey City — sitting directly across the Hudson from Lower Manhattan — anchors the directory's records here. The city has reshaped itself substantially through the past three decades alongside the surrounding waterfront development; office towers, residential construction, and a steady inflow of finance employment have transformed a working-port city into one of the larger commercial centers in the broader New York metro. The 201 footprint covers Bergen and Hudson counties along with parts of the surrounding northern New Jersey region.

In records the directory has compiled for 201 numbers, other New Jersey cities — Cherry Hill, Edison, Elizabeth, and Newark — recur frequently. None of those are inside the 201 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across New Jersey and addresses linked across multiple cities. The directory currently documents 682 distinct prefixes within 201 in detail, a working subset of the prefix population the code carries.

Jersey City's home values come in well above the US median, in line with broader Hudson waterfront pricing pressure. Median household income runs notably above the national reading, the city's median age sits a few years under the US figure, and population places Jersey City among the larger cities in New Jersey — substantial enough to anchor its own civic identity within the broader New York metropolitan area, even as the city has continued to absorb substantial residential and commercial growth.
