Random New Jersey Phone Number Generator

The Random New Jersey Phone Number Generator gives you one to ten made-up phone numbers that start with a real New Jersey area code. Each number is written the way Americans write them, +1 (201) 555-0123 style, and shows on its own card with a copy button. The area code is chosen from the nine currently assigned to New Jersey; the seven digits after it are random. That makes the results useful as test data for anything that has to look like a Garden State number, while making it unlikely you will land on a specific person's line by design.

What you can set

Just the count. Enter a number from 1 to 10 and press Generate Phone Number. There is no area-code picker on this page: every result draws its code at random from the New Jersey list, so a batch of ten will usually contain several different codes. If you need all numbers in one area code, generate a batch and edit the three digits in parentheses. Every card is labeled with the state and country so you can tell it apart from results copied from the other state generators.

What the numbers look like

Format is +1 (AAA) NNN-NNNN: the +1 country code for the North American Numbering Plan, the area code in parentheses, then a three-digit exchange and a four-digit line number. The exchange and line digits are fully random. Real exchanges never begin with 0 or 1, and the generator does not enforce that rule, so roughly one number in five will have an exchange that could not actually be dialed. For form validation and database seeding that is harmless; for a phone number that a reader should believe, pick a result whose exchange starts with 2 through 9.

Ways people use it

• Testing address and contact forms for apps that serve New Jersey customers, including checks that the area code is accepted and formatted correctly.
• Filling demo CRMs and spreadsheets with realistic-looking local contacts before a client presentation.
• Fiction, scripts and mockups set in Newark, Jersey City, Trenton or the Shore, where a 203 or 212 number would look out of place.
• Teaching examples for lessons on US phone number structure and area codes.

New Jersey area codes

New Jersey has more area codes than its size suggests because of its population density and its history of overlays. The tool uses the nine below.

One code is missing from the list: 640, the overlay that started serving the 609 region in 2018. Numbers with 640 are real and increasingly common in Trenton and along the Shore, so if your test data should cover every possibility, add a few by hand. Because every part of New Jersey now has at least two codes, ten-digit dialing is mandatory statewide, which is why the tool always includes the area code.

The site has the same generator for neighboring and far-off states, including California, Texas, North Carolina and Colorado, and for other countries such as Canada and the UK. See all phone number generators for the full list.
