Union City, NJ is currently using two area codes 201 and 551. Union City, NJ utilizes an area code overlay in which area
codes 201 and 551 serve the same geographic area. The area code overlay which is in use in Union City, NJ today was established in 2001 at which time area code 551 was created as an overlay of area code 201.
Area code 201 originally covered the entire state of New Jersey, including Union City, New Jersey when it was established in 1947. Ten digit dialing (area code + seven digit number) is necessary in Union
City because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
Today, in addition to Union City, NJ, area codes 201
and 551 serve the larger communities of Bayonne, Bergenfield, Cliffside Park, Englewood, Fair Lawn, Fort Lee, Hackensack, Hoboken, Jersey City, Kearny, North Bergen, Paramus, Ridgewood, Teaneck, and West New
York, NJ in addition to many smaller communities. |
