A 201 reads North Jersey native
Restricted to Hudson and Bergen Counties since 1991, 201 carries serious commuter-belt credibility — distinct from the 551 overlay assigned to newer lines.
Get a 201 North Jersey, 973 Newark, 609 Trenton, 732 central NJ, 856 South Jersey or any of New Jersey's 10 area codes on the phone you already own. The Garden State's full prefix map — pick the code your customers will recognise on caller ID.
New Jersey has 10 active area codes — 201, 551, 973 and 7 more. You can get a virtual New Jersey phone number from any of these area codes through CallMama without a US address or SIM card.
New Jersey received one original area code in 1947: 201, covering the entire state. 609 was carved off in 1957 for southern NJ (Trenton south to Atlantic City) leaving 201 with the densely populated north.
The 1990s and 2000s rebuilt the map. 908 split from 201 in 1991, 973 split off in 1997 for Newark and Essex County, 732 split from 908 in 1997 for central NJ, and 856 split from 609 in 1999 for Camden and the south.
Overlays followed as cellular demand exploded: 551 (over 201, 2001), 862 (over 973, 2001), 848 (over 732, 2001) and 640 (over 609, 2018) — keeping pace with North Jersey's commuter density.
New Jersey is the most densely populated state in the US — over 1,200 people per square mile, more than five times the national average. That density is why New Jersey runs 10 area codes despite being the fourth-smallest state by land area.
