What number is 551

What is 551?

551 is a three-digit area code used in North America. It is an overlay for the 201 area code in northern New Jersey and covers the same geographic region. The 551 area code was created to provide additional phone numbers to the area as the 201 area code was running out of available phone numbers.

The 551 area code covers several cities in northern New Jersey, including Jersey City, Hoboken, Hackensack, and Teaneck. It is one of the newer area codes in the United States, having been established in 2001.

When calling a phone number with the 551 area code, it is important to include the full 10-digit phone number, including the area code, even if the caller is located within the same geographic region. This is because the 551 area code is an overlay, meaning it shares the same geographic region as the 201 area code, and multiple area codes may apply to the same location.
