What Is an Area Code?
An area code is the first three digits of a phone number. It shows which part of the United States the number belongs to. For example, area code 914 is for Westchester County, 212 is for New York City, and 213 is for Los Angeles, California. These codes help phone networks connect calls to the right area.
