An area code is a three-digit number that is used to identify a particular telephone service region in a country. In the United States and Canada, area codes are used as the first three digits of a 10-digit phone number to identify a particular geographic region. For example, the area code 212 is used in the state of New York to identify the phone numbers in the Manhattan borough of New York City. Area codes are used to route phone calls to the correct location and to help prevent phone numbers from being duplicated in different parts of the country. In some cases, a single area code may cover a large geographic region, while in other cases, multiple area codes may be used to serve a smaller region.
