OR Find the Cities/Towns in an Area Code:
Important note on using this feature:
The database that powers this feature is based on US Census data.
If your search returns more than one area code, either the city/town lies within an overlay area, or an area code boundary passes through the city/town.
The database contains only cities and towns with populations greater than 20,000. To find the area code for a smaller city or town, try searching on one or more area codes you think might be correct, or search on the entire state . Seeing a list of the larger cities/towns in these area codes may give you insight into where the area code boundaries lie. If there is still doubt in your mind, you can check with your long distance operator.
