The Complete Guide to the 973 Area Code in Northern New Jersey

Introduction

The 973 area code serves northeastern New Jersey — one of the most commercially dense and historically significant regions on the entire East Coast. For anyone calling a business in Newark, tracking an unfamiliar 973 number, or building a local presence in northern New Jersey, understanding this code gives you a clear advantage. This guide covers every angle: which cities and counties the 973 area code spans, how and when it was created, the Eastern Time zone details, the industries driving demand for local numbers, and how to get a virtual 973 phone number in minutes. The full picture is right here — read on.

What Is the 973 Area Code?

The 973 area code is a North American Numbering Plan (NANP) geographic code assigned to northeastern New Jersey. It is not a toll-free or premium-rate code — calls to 973 numbers are billed at standard domestic rates, the same as any other US local call. The region shares its territory with the 862 overlay code, introduced in 2001 when the 973 number pool itself began filling up. Because both codes coexist, every caller within the region must dial all 10 digits — the area code plus the seven-digit number — even when calling a neighbor.

Below is a quick at-a-glance summary of everything you need to know about the 973 area code.

Where Is the 973 Area Code Located?

The 973 area code stretches across the northern tier of New Jersey, beginning just west of the Hudson River and extending into the rolling hills of Sussex and Warren counties. Essex County anchors the eastern portion with Newark at its heart — New Jersey's largest city and a major hub for air travel, finance, law, and culture. Morris County extends westward with a prominent belt of corporate headquarters and pharmaceutical campuses, while Passaic County brings Paterson, one of America's first planned industrial cities, into the mix.

Major Cities in the 973 Area Code

The 973 footprint covers dozens of cities, townships, and boroughs across five counties. Here are the largest and most notable communities.

Counties and Neighboring Area Codes

The 973 area code spans five New Jersey counties: Essex, Morris, Passaic, Sussex, and the eastern portion of Warren. It borders the 201 area code to the east along the Hudson River corridor, the 908 code to the south, and the 845 New York code to the north. Businesses across these neighboring regions routinely connect with customers across the entire greater northern New Jersey market.

History of the 973 Area Code

The story of the 973 area code begins with the exhaustion of New Jersey's original 201 code. For decades, 201 covered virtually all of New Jersey, making it one of the most number-depleted codes in the country by the mid-1990s. Explosive population growth, rapid corporate expansion, and the surge in mobile phone adoption combined to push the 201 pool toward exhaustion far ahead of schedule.

On June 1, 1997, regulators split 201 into two regions: the northeastern Hudson River corridor retained 201, while the rest of northern New Jersey was reassigned to the brand-new 973 area code. Four years later, in 2001, the 862 overlay was added to the same 973 territory. This means the region now has two valid area codes sharing the same geography — both 973 and 862 numbers reach communities in Newark, Paterson, Morristown, and beyond.

Why Northern New Jersey Needed a New Code

• New Jersey's population grew by more than 500,000 between 1980 and 1997, consuming phone numbers at a rapid pace.
• Corporate expansion in Morris County drew pharmaceutical giants, insurers, and tech companies — each requiring hundreds of dedicated business lines.
• The mobile phone boom of the mid-1990s accelerated number exhaustion across the entire 201 pool far faster than forecasters predicted.
• Regulators chose a geographic split in 1997 to preserve 7-digit local dialing, though the 862 overlay added in 2001 made 10-digit dialing mandatory anyway.

973 Area Code Time Zone

Every community within the 973 area code observes Eastern Time — Eastern Standard Time (EST, UTC−5) from early November through mid-March, and Eastern Daylight Time (EDT, UTC−4) from mid-March through early November. New Jersey follows the standard US daylight saving schedule, so clocks spring forward in March and fall back in November alongside the rest of the East Coast.

Calling the 973 Area Code from Other Time Zones

Standard business hours in the 973 region run 9 AM – 5 PM ET. The table below shows the best calling window when reaching a 973 number from another US time zone.

West Coast callers who dial a 973 number at 9 AM Pacific find Newark already three hours into its business day — making midday Pacific calls ideal for East Coast outreach. Because the 973 area code shares Eastern Time with New York City, coordinating calls between Newark, Morristown, and Manhattan is seamless.

Why Businesses Choose a 973 Area Code

Northern New Jersey is one of the most economically productive corridors in the country. Its proximity to New York City — combined with lower operating costs, direct airport access via Newark Liberty International, and a deep professional talent pool — makes the 973 region prime territory for corporate headquarters, pharmaceutical research, financial services, and logistics operations. A local 973 area code number signals to customers in Newark, Morristown, and Paterson that you are genuinely part of their market.

• Legal and professional services — Newark's federal courthouse and extensive law firm ecosystem create steady demand for credible 973 numbers.

Is the 973 Area Code Safe? Common Scams to Watch

The 973 area code is entirely legitimate — it is used every day by millions of New Jersey residents, businesses, healthcare providers, and government agencies. However, like every US area code, 973 numbers can be spoofed by fraudsters who want calls to appear local and trustworthy. Here is what to watch for.

Common 973 Phone Scams

• IRS and government impersonation — callers claim to be from the IRS, Social Security Administration, or a New Jersey state agency and demand immediate payment or personal information.
• Utility shutoff threats — scammers pose as PSE&G or Jersey Central Power & Light and threaten service disconnection unless you pay immediately by gift card or wire transfer.
• Neighborhood spoofing — fraudsters display a 973 number matching your own prefix to increase the likelihood you pick up.
• Healthcare billing fraud — given the region's dense hospital and insurance sector, scammers pose as billing departments to steal personal data or insurance information.
• Prize and lottery scams — callers claim you have won a local prize and request a fee or personal details to release the winnings.

How to Protect Yourself

• Let unknown 973 numbers go to voicemail — legitimate callers always leave a message.
• Never share your Social Security number, bank account, or payment card over the phone unless you initiated the call.
• Use a reverse-lookup tool to research unfamiliar 973 numbers before calling back.
• Report suspicious calls per the FCC guidelines for unwanted calls.
• Enable your carrier's built-in spam screening (T-Mobile Scam Shield, Verizon Call Filter, AT&T Call Protect).
