Area Code
Area code is a 3-digit telephone number prefix assigned to a geographic area in the United States and used before an individual 7-digit telephone number. You can use area codes to define your target location.
Remember that you are selecting geography and not just records containing telephone numbers with selected area codes.
Area code geographies might overlap. However, even if you select overlapping area codes, you will get no duplicate records because they will automatically be eliminated.
You can limit the results of your search to records containing ZIP+4 information. For more information, see Order Only Records with ZIP+4.
