What Is the 201 Area Code?
Area code 201 is one of the original area codes the Bell System activated on October 19, 1947, and it was the very first to go live under the new North American Numbering Plan.
It originally covered the entire state of New Jersey, from the New York suburbs down to the Delaware Bay. As the state's population grew, regulators split that single code into smaller regions to keep the numbering plan from running dry.
The southern half of the state split away to form area code 609 in 1956. Area code 908 split off in 1991 to cover north-central New Jersey.
Then, in 1997, area code 973 took Essex, Passaic, Morris, and Sussex counties, leaving 201 with only Bergen and Hudson County. That smaller footprint is what the 201 area code covers today.
- Activado: October 19, 1947
- National first: the first area code placed into service under the NANP
- Split off: area code 609 (1956), area code 908 (1991), area code 973 (1997)
- Overlay partner today: 551
- Regla de marcación: marcación local obligatoria de 10 dígitos
Counties and Cities the 201 Area Code Covers
Regulators added the 551 area code as an overlay on December 1, 2001, layering it directly on top of 201 rather than splitting the territory again.
That overlay covers the same footprint: Bergen and Hudson County in the northeastern corner of New Jersey, bordering New York City across the Hudson River.
Major cities carrying a 201 area code number include Jersey City, Hoboken, Hackensack, and Bayonne, plus dozens of smaller Bergen County towns.
Jersey City anchors the region as a finance and corporate hub, drawing business lines from Manhattan-facing firms that want a New Jersey presence.
Hoboken adds a dense concentration of startups and professional services along the waterfront, while Hackensack and Bayonne round out the region's healthcare and logistics base.
Business owners serving customers on both sides of the Hudson should also know about the 917 area code, which covers all five NYC boroughs and matters if your customer base reaches into Manhattan too.
Most new mobile numbers and small-business lines in Bergen and Hudson County now draw from 551, while area code 201 remains the older, more recognized prefix in the region. That legacy status still carries weight with local customers reading a caller ID.
201 Area Code Time Zone and Dialing Rules
The 201 area code sits entirely inside the Eastern Time Zone, matching the rest of New Jersey and New York City. Eastern Standard Time (EST) runs UTC −5:00 from early November through mid-March.
Eastern Daylight Time (EDT) runs UTC −4:00 the rest of the year. That places northeastern New Jersey in the same time zone as Manhattan, simplifying scheduling for teams working across the Hudson.
Because 201 shares its territory with 551, the same seven-digit sequence can exist under either code. Ten-digit dialing became mandatory for the region the day the overlay launched in 2001, and it still applies today.
Even a call between two offices on the same Jersey City block needs the full prefix: (201) XXX-XXXX. International callers dial +1 (201) XXX-XXXX.
- Hora estándar del este (EST): UTC −5:00, desde principios de noviembre hasta mediados de marzo
- Hora de verano del este (EDT): UTC −4:00, desde mediados de marzo hasta principios de noviembre
- vs. Chicago: one hour ahead
- contra Los Ángeles: tres horas por delante
- Formato de marcación local: (201) XXX-XXXX — 10 digits required
- Formato internacional: +1 (201) XXX-XXXX

How to Identify and Avoid 201 Area Code Scam Calls
The same local recognition that makes a 201 area code number valuable for businesses also makes it attractive to scammers. Caller ID spoofing software lets fraudsters display a fake number on a screen.
The call can originate anywhere in the world, borrowing the prefix's trust without any real connection to New Jersey.
Common scripts here include callers posing as toll-road billing agents or utility collectors demanding fees. Others pose as bank fraud investigators or tech support reps citing a well-known local company.
None of these callers demand instant payment by gift card or wire transfer, and a real area code 201 prefix on the screen proves nothing about who is calling.
El Guía de suplantación de identidad de la FCC publica orientación continua que cubre exactamente estas tácticas y cómo denunciarlas.
Dejar que las llamadas desconocidas vayan al correo de voz, filtrarlas con las herramientas gratuitas de su proveedor y reportar números sospechosos reducen las probabilidades de perder dinero por una llamada falsificada.
- Deje que las llamadas no reconocidas vayan al correo de voz; las personas que llaman legítimamente dejan un mensaje.

- Informe llamadas sospechosas a la FCC y la FTC.
“The 201 area code tells a Bergen or Hudson County customer that the business calling them belongs here — and that recognition is worth more than any unfamiliar toll-free number.”
Why Businesses Choose a 201 Area Code Number
A local 201 area code number tells a Bergen or Hudson County customer the business belongs there, even if the team sits in another state.
Ese reconocimiento genera tasas de respuesta más altas, ya que es mucho más probable que se ignore un número gratuito desconocido o de otro estado que un prefijo que un cliente ya ve en los teléfonos de amigos y vecinos.
A 201 area code number also builds trust faster in a market as competitive as the New York metro area. Vendors and service businesses pitching Jersey City or Hoboken clients gain instant credibility with a local listing on their website and invoices.
Combinando esa identidad con proveedores de servicios voip construido para el crecimiento ayuda a que un equipo pequeño suene como un jugador local establecido.
