New Jersey, positioned in the Northeastern region of the United States, utilizes multiple area codes as part of its telecommunications framework. The state is primarily served by several area codes, including 201, 551, 609, 732, 848, 856, 908, and 973, reflecting its dense population and diverse urban centers. As of the 2020 census, New Jersey had a population of approximately 9.3 million, making it one of the most densely populated states, which necessitated the allocation of multiple area codes to accommodate its extensive communication needs.
The original area code for New Jersey, 201, was established in 1947, and has since undergone several splits and overlays to manage demand. For instance, the 973 area code, introduced in 1997, was created from the original 201 area to serve the northern and western regions of the state, while 609 and 856 were introduced to address the growing population in southern New Jersey. The overlay of 551 onto 201 in 2001 further reflects the need for additional numbers for a state with a high concentration of residents and businesses.
Unique characteristics of New Jersey's telecommunications landscape include the rapid adoption of mobile devices and VoIP technology, contributing to an increasing demand for new telephone numbers. The state’s proximity to major metropolitan areas like New York City and Philadelphia also influences call patterns and telecommunications services, adding another layer of complexity to its communication infrastructure.

New Jersey has 9 area codes (609, 201, 551, 862, 973, 856, 732, 848, 908). These area codes are split between cities or states, so if you want to call to New Jersey, you need to know exactly where you would like to call.
The first 3 digits to call New Jersey may vary depending on where you want to call to, being one or the other depending on the region or city. Take a look at our listing above to find out which area code you need.
Calling New Jersey from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for New Jersey. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
When making calls within the United States, dialing +1 depends on several factors. On most modern mobile phones, carriers automatically recognize the country code when calling within the U.S., so dialing +1 is usually not required; you can simply enter the area code followed by the phone number, such as 213-555-1234. If you’re using a landline, dialing 1 (the U.S. country code) before the area code and phone number is often necessary for long-distance calls; for example, calling from one state to another may require dialing 1-213-555-1234. When calling the U.S. from another country, dialing +1 is necessary, so a call from abroad would be formatted as +1-213-555-1234. VoIP and internet-based calling platforms, like Skype and WhatsApp, generally handle country codes automatically, making it unnecessary to dial +1 manually for U.S. numbers.
