The 201 area code serves Hudson County and most of Bergen County in northeastern New Jersey, including Jersey City, Hoboken, Bayonne, Union City, and Hackensack. These areas sit directly across the Hudson River from Manhattan. AT&T assigned the 201 area code in 1947, making it the first area code in the North American Numbering Plan. In 2001, officials added the 551 area code as an overlay. Today, both area codes serve the same region, and callers must use 10-digit dialing for every local call, even when calling a nearby number.

Is 201 a Real Area Code? Is It Safe?
Yes, 201 is a legitimate, long-standing U.S. area code, not a scam code. However, any area code, including 201, can be “spoofed” by scammers who disguise their caller ID to look local and trustworthy. A call from a 201 number is not automatically safe just because the area code is real. If you receive an unexpected call from a 201 number asking for money, personal information, or gift cards, treat it with the same caution you would any unknown caller; the area code tells you nothing about who is actually dialing.
