New Jersey Area Codes: Complete Guide to All 10 NJ Codes (2026)

New Jersey has 10 area codes packed into the most densely populated state in America — 1,259 people per square mile across just 8,723 square miles of land. NJ's original area code, 201, was the very first area code assigned in the entire North American Numbering Plan in 1947. Today, 9.5 million people share 10 codes across 21 counties.

This is the state where Thomas Edison held 1,093 patents, where the Hindenburg burned in 34 seconds, where the first organized baseball game was played, where all the Monopoly streets are real, where Alexander Hamilton was shot in a duel on the cliffs of Weehawken, where Washington crossed the Delaware to win the Revolution's turning point, where Bruce Springsteen was born to run, and where there are more diners per square mile than anywhere else on Earth. New Jersey is the Garden State — and the state that invented everything.

Thomas Edison: 1,093 Patents from New Jersey

Thomas Edison established his first major laboratory in Menlo Park, NJ in 1876. Over the next decade, he filed approximately 400 patents from this location, inventing the carbon-button telephone transmitter, the phonograph (1877), and a complete system of incandescent electric lighting. His first patent ever — the electric vote recorder — was granted June 1, 1869.

In 1887, Edison moved to his final laboratory in West Orange, NJ, where he produced more than half of his lifetime total of 1,093 U.S. patents. West Orange inventions included the Kinetoscope (early motion picture viewer), the Kinetograph (movie camera), an early fluoroscope, and the rechargeable battery. Edison died in West Orange on October 18, 1931.

The Hindenburg: 34 Seconds Over Lakehurst (1937)

On May 6, 1937, at approximately 7:25 PM, the German airship LZ 129 Hindenburg — 803 feet long, filled with 7,062,000 cubic feet of hydrogen — burst into flames while attempting to land at Lakehurst Naval Air Station in the 732/848 area code. The fire destroyed the entire airship in 34 seconds.

Of the 97 people on board (36 passengers, 61 crew), 35 were killed, plus 1 ground crew member — 36 total deaths. Remarkably, 62 survived. Radio reporter Herbert Morrison recorded his famous broadcast: "Oh, the humanity!" The disaster effectively ended the age of the rigid airship. The Hindenburg had made 17 transatlantic round trips in its only full year of service.

Atlantic City: The Boardwalk, Monopoly, and the First Casino

The Atlantic City Boardwalk opened June 26, 1870 — the first boardwalk ever built in the United States. Initial cost: just $5,000. Originally 8 feet wide and 1 mile long, it was designed to keep sand out of hotel lobbies. Today it stretches 5.5 miles — the longest boardwalk in the world.

When Parker Brothers published Monopoly in 1935, all the street names came from Atlantic City: Boardwalk, Park Place, Baltic Avenue, Mediterranean Avenue — all real streets in the 609/640 area code.

A 1976 referendum legalized casino gambling, restricted to Atlantic City. Resorts International opened as the first legal casino outside Nevada on May 26, 1978, with 84 table games and 893 slot machines on 33,735 square feet of floor space.

Washington Crossing the Delaware: The Battle of Trenton (1776)

On the night of December 25–26, 1776, George Washington led 2,400 Continental Army troops across the ice-choked Delaware River into Mercer County, NJ (609/640 area code). Temperatures ranged from 29 to 33°F with wind, rain, snow, and sleet. Colonel Henry Knox managed to transport 18 cannons across the 300-yard-wide river.

The Battle of Trenton began at approximately 8:00 AM on December 26. The surprise attack against 1,380 Hessian soldiers was devastating: 22 killed (including commander Colonel Johann Rall), 84 wounded, 886 captured. American casualties were negligible. The victory rescued the Revolution and inspired re-enlistments that kept the army together.

The Burr-Hamilton Duel: Dawn at Weehawken (1804)

At dawn on July 11, 1804, sitting Vice President Aaron Burr and former Treasury Secretary Alexander Hamilton met on a narrow ledge on the Palisades cliffs in Weehawken, NJ (201/551 area code). Both men left Manhattan at 5:00 AM, rowed separately across the Hudson. The Weehawken site was popular for dueling — NJ was less aggressive than New York in prosecuting duelists.

Hamilton had told confidants he intended to "throw away his shot" — his bullet hit a tree branch above Burr's head. Burr's shot struck Hamilton in the abdomen above the right hip, fractured a rib, tore through his diaphragm and liver, and lodged in his spine. Hamilton survived approximately 31 hours, dying on July 12, 1804.

Bruce Springsteen: Born to Run from the Jersey Shore

Bruce Springsteen was born September 23, 1949, at Monmouth Medical Center in Long Branch, NJ, and raised at 87 Randolph Street in Freehold (732/848 area code). He launched his career playing venues in Asbury Park — the Stone Pony (opened 1974) became his legendary home stage.

Born to Run (his 3rd album) was released August 25, 1975. Recording took 14 months, with nearly half that time on the title track alone. Columbia spent $250,000 on promotion. Springsteen appeared simultaneously on the covers of TIME and Newsweek the week of October 27, 1975 — the first rock star to achieve this. The album has sold over 6 million copies and was inducted into the Library of Congress National Recording Registry in 2003.
