New Jersey area codes

New Jersey was the third state to join the Union in 1787. Today, it is home to nearly 10 million people and the most number of millionaires in the United States. Nearly every resident has a phone number using at least one of the ten New Jersey area codes. You can identify a caller by looking through the New Jersey phone numbers database. 

The typical phone number in New Jersey in the early 90s used the 2L-5N format. Two letters tell you what the switchboard to dial. The last five numbers were what you gave the operator to route your call.

The demand for new phone numbers soon caused a shift to an all-number system. Three digits replaced the two letters, and the last four digits were the phone number owner’s personal code.

Soon enough, the 7-digit system phased into a 10-digit numbering system as demand for new phone numbers increased. By adding a three-digit area code to the seven digits, phone companies expanded the available pool of numbers. Area codes represent a specific geographic area within New Jersey, based on the North American numbering plan. 

Take your typical ten-digit Newark phone number, 973-NJJ-XXXX, and think of it as a physical house address. 

973 is the area code. In a house address, this would be your county of residence – in this case, Newark. The three digits that come next, NJJ, is the prefix code. In a house address, this would be your town or street within Newark.

The last four digits, XXXX, is the unique line number. In a house address, this would be your house number, flat number, or room number.

New Jersey started with one area code in 1947 – area code 201. One area code was enough to cover all phone owners in the state at the time. Since New Jersey has increased, the state has created 10 area codes using overlay and geographic split.

Besides connecting you with the person you wish to call, area codes also let you identify an unknown caller’s location. But you will need a reverse phone search to get more information about the caller’s address and public records on the New Jersey phone numbers database. Several persons can have the same area code if they live in the same area. Also, several persons can have the same prefix code if they are neighbors. However, line numbers are unique. So, two persons cannot have the same line number, but one person can have several lines. Information on phone number owners is accessible on the New Jersey phone numbers database.
