201 Area Code
for Jersey City Businesses

Area code 201 is the original telephone area code for New Jersey, established in 1947. It covers northeastern New Jersey including Jersey City, Hoboken, Bayonne, and Union City in the New York metropolitan area.

Area code 201 holds the distinction of being one of the original 86 area codes established in 1947 as part of the North American Numbering Plan. Originally covering the entire state of New Jersey, 201 was strategically assigned to the Garden State because AT&T's Bell Laboratories was headquartered in North Jersey and played a key role in developing the numbering plan. The code initially served all of New Jersey until 1958, when the state's growing population necessitated the creation of area code 609 for South Jersey. As suburban growth continued around New York City, further splits occurred: 908 was created in 1991 for western regions, followed by 973 in 1997 for additional northern territories. By 2001, the increasing demand for phone numbers led to the implementation of the 551 overlay, which serves the same geographic area as 201. Today, 201 remains one of America's most historic area codes, serving the densely populated Hudson and Bergen County regions that form New Jersey's gateway to New York City.
