973 Area Code: Newark, New Jersey — Cities, Overlay & Business Guide

The 973 area code is the telephone code for Newark, New Jersey, and the northern part of the state — Essex, Passaic, Morris, and Sussex counties, on Eastern Time. It stretches from Newark's downtown and Ironbound district out through Paterson, Montclair, and the Morris County suburbs — a territory that ships containers, invents medicines, and underwrites insurance for much of the country. For a business, the prefix is shorthand for North Jersey credibility.

This guide explains what the 973 area code covers, the cities and communities inside it, how the 862 overlay changed dialing, which codes sit next door along the Hudson and in central Jersey, what powers the Newark-area economy, and how any business can activate a 973 number in minutes.

973 is the North American Numbering Plan code serving Newark and a broad swath of northern New Jersey, including Essex, Passaic, and Morris counties. It was created in 1997, split from the 201 territory that once covered all of North Jersey, as the region's appetite for phone, fax, and mobile lines outgrew a single code. The later addition of the 862 overlay means all local calls in the territory are dialed with ten digits.

• Dialing format: (973) 555-0123
• International format: +1 973-555-0123
• Time zone: Eastern Time (ET) — UTC−5 Standard, UTC−4 Daylight Saving
• Year introduced: 1997

The code runs from New Jersey's largest city westward into the suburbs and hills of Morris County — a mix of dense urban neighborhoods, historic mill towns, commuter villages, and corporate campuses, all within the orbit of New York City yet firmly Jersey in identity.

Newark

Newark is the state's largest city and the anchor of the code. Its downtown holds universities, a performing arts center, and corporate towers, while the Ironbound district beside Penn Station serves some of the best Portuguese and Brazilian food in the country. The city's airport and seaport make it one of the East Coast's great gateways.

Paterson

Paterson grew up around the Great Falls of the Passaic River, whose water power made it America's first planned industrial city. The falls are now a national historical park, and the city remains one of New Jersey's most diverse, with silk-era mills finding new lives around its historic core.

Morristown

Morristown, the Morris County seat, pairs Revolutionary War history with a thriving modern downtown of restaurants, offices, and a lively green. It has become one of North Jersey's most desirable business addresses, drawing law firms, financial offices, and headquarters operations to its walkable center.

Montclair

Montclair is the territory's arts suburb — an Essex County town known for its film festival, galleries, independent bookshops, and a commuter rail link to Manhattan. Its mix of Victorian neighborhoods and busy commercial strips makes it a magnet for creative professionals.

Counties and Communities the 973 Code Serves

The prefix reaches across four northern New Jersey counties, from the dense cities near the Hudson to the hills of the northwest. Anyone checking whether a local number will land in the right market can use the list below as a quick reference for the communities the code covers.

• Essex County — Newark, Montclair, Bloomfield, West Orange, and the Oranges
• Passaic County — Paterson, Clifton, Passaic, and Wayne
• Morris County — Morristown, Parsippany, and Dover
• Sussex County and the shared 862 overlay — every community above can also receive an 862 number on the identical footprint

Less than a decade after 973 launched, North Jersey again ran short of numbers, and the 862 overlay was layered across the identical territory. Existing lines kept their digits, newer assignments often carry 862, and ten-digit dialing became the rule for every local call in the region.

The neighboring map reflects the state's density. Along the Hudson waterfront — Jersey City, Hoboken, and Bergen County — the original 201 area code and its 551 overlay serve the towns facing Manhattan. To the south, 908 covers central Jersey communities such as Elizabeth, Westfield, and the Somerset hills. Together these codes carve one of America's most crowded telephone landscapes into clear local identities.

• 862 — the overlay sharing the exact same North Jersey footprint as 973
• 201 / 551 — the Hudson waterfront and Bergen County
• 908 — central New Jersey, from Elizabeth toward the Somerset hills

The code observes Eastern Time (ET) — UTC−5 during Standard Time and UTC−4 during Daylight Saving Time, which runs from mid-March to early November. Newark keeps the exact same clock as New York City, a few miles east.

For business, that alignment matters: a North Jersey number operates on the same schedule as Wall Street, Midtown, and the entire East Coast corridor. Companies serving metro-area clients can promise same-business-day responsiveness without any time-zone arithmetic.

Newark's economy moves goods, medicine, and money at national scale. Its firms work shoulder to shoulder with Manhattan — many keep a North Jersey line beside a 212 area code listing so clients on both sides of the Hudson see a local presence — and the region's own industrial base stands on three deep pillars.

Port & Logistics

Port Newark and the adjacent container terminals form one of the busiest cargo complexes on the Atlantic coast, feeding warehouses and rail yards across the region. Newark Liberty International Airport adds passenger and air-freight capacity, making the city a complete gateway for goods and travelers entering the Northeast.

Pharmaceuticals

Northern New Jersey has been called the medicine chest of the world, and the corridor through Essex and Morris counties helped earn the title. Global drugmakers, research campuses, and a deep bench of chemists and regulatory specialists keep pharmaceutical discovery and manufacturing central to the region's identity.

Finance & Insurance

Major insurers are headquartered in downtown Newark, where their towers have shaped the skyline for a century. Around them cluster banks, accounting practices, and fintech offices that serve both the local market and the wider New York metropolitan economy.

A similar dynamic plays out in the 215 area code, where Philadelphia companies weigh the same trade-offs.

A North Jersey number is available to any business through a cloud phone provider — no Newark office or New Jersey address required. Activation takes minutes in three steps.

1. 1Choose a provider — create an account with a cloud phone service such as MeraTalk that carries Newark-area numbers.
2. 2Pick a number — search available 973 combinations and select one that fits the brand.
3. 3Activate and route — verify the account and point the number anywhere; calls ring on any device, whether a desk phone near Penn Station or a mobile app across the ocean.

Once live, customers reach the business at (973) 555-0123 from within the US or +1 973-555-0123 internationally, and features like auto-attendant, call recording, and CRM integration can be enabled immediately.

North Jersey does business with the world through its port and airport, so international callers reach 973 numbers constantly. The pattern follows the standard North American format: dial the local international exit code, then the US country code 1, then the ten-digit number.

• From the UK and most of Europe: 00, then 1 973 and the seven-digit number
• From Brazil — a natural link given the Ironbound's community ties: 0021 or another carrier code, then 1 973 and the number
• From any mobile phone worldwide: +1 973 followed by the seven digits — the plus sign substitutes for the exit code
• From Canada and other North American Numbering Plan countries: simply 1 973 and the number

Newark runs on Eastern Time, so overseas callers should plan around it. A 9 am to 5 pm ET business day corresponds to 2 pm to 10 pm in London and 10 am to 6 pm in São Paulo during overlapping daylight-saving periods — a comfortable window for both European and South American partners.

Fraudsters spoof local prefixes because people answer numbers that look like their own community, and North Jersey's dense, diverse population makes it a frequent target. A local-looking caller ID proves nothing about where a call actually originates.

• Utility shut-off threats — impostors posing as the electric or gas company demand instant payment; genuine utilities issue written notices before any disconnection
• Toll and traffic-fine texts — messages claiming unpaid highway tolls with a payment link; official agencies do not collect this way
• Immigration and court impersonation — callers threaten arrest or deportation unless fees are paid by gift card or wire transfer
• Package delivery cons — fake customs or redelivery fees tied to shipments supposedly held at the port or airport

The defense is the same everywhere: never pay by gift card, never confirm personal details to an inbound caller, and phone the organization back on its published number. Suspicious calls can be reported to the FCC and the New Jersey Division of Consumer Affairs.
