ZIP Codes in New Jersey
New Jersey is the most densely populated state in the country, and its ZIP codes reflect that intensity - with around 9.3 million residents packed into a relatively small footprint, New Jersey has more ZIP codes per square mile than almost anywhere else in the US. Wedged between New York City and Philadelphia, much of the state functions as commuter territory for both major metro areas, while the Jersey Shore draws heavy seasonal tourism along the Atlantic coast.
How ZIP Codes Are Organized Across the State
New Jersey's ZIP codes fall within the 07000–08999 range under the USPS system. Newark and the northern New Jersey suburbs, closest to New York City, occupy the lower end around 071xx, Trenton, the state capital, sits near 086xx, and southern New Jersey, including Camden across the river from Philadelphia, carries codes closer to 081xx.
New Jersey's Major Metro Areas by Population
The chart below shows how population concentrates heavily in northern New Jersey, closest to New York City, with southern New Jersey considerably less dense.
Newark's ZIP codes cover New Jersey's largest city, home to one of the busiest airports on the East Coast and a major port that handles a huge share of the region's shipping traffic. Jersey City, directly across the Hudson River from Manhattan, has transformed dramatically in recent decades into a dense high-rise financial district of its own, sometimes called "Wall Street West."

North Jersey and the New York Commute
Much of northern New Jersey functions as an extension of the New York City commuter belt, with towns close to the border with New York seeing daily rail and ferry traffic into Manhattan. ZIP codes here carry some of the highest property values in the state, driven by proximity to the city and access to transit options like PATH trains and NJ Transit rail lines.
South Jersey and the Jersey Shore
South Jersey has a noticeably different character, with Camden sitting directly across the Delaware River from Philadelphia and functioning more within that metro area's orbit than New York's. Along the coast, the Jersey Shore's famous boardwalk towns - Atlantic City, Wildwood, and Cape May among them - see enormous seasonal population swings, with ZIP codes here reflecting a mix of gaming, tourism, and beach-town real estate.
Why ZIP Codes Matter Beyond Mail
In New Jersey, ZIP codes are closely tied to property taxes, among the highest in the country, and to school district quality, both of which can vary dramatically between adjacent towns given the state's dense patchwork of small municipalities. The Jersey Shore's tourism and gaming industries rely on ZIP-level data to plan for massive seasonal population swings. And the Port of Newark-Elizabeth, one of the busiest on the East Coast, depends on ZIP-level logistics coordination for the enormous volume of goods passing through it.
Border Regions and Neighboring States
New Jersey shares borders with New York, Pennsylvania, and Delaware, with the Hudson and Delaware Rivers forming much of its boundary. To the north, the New York border drives the state's dense commuter suburbs. To the west, Pennsylvania connects Camden and Trenton into the broader Philadelphia metro economy. And to the south, the Delaware Bay separates New Jersey from Delaware itself.
