Help for Area Code Search Help for Area Code Search Search on area code Entering a telephone area code retrieves a list of our locations nearest the geographic center of that area code, and also shows mileage and compass direction from the center of that area code to each location. The locations found will not be limited to the specified area code.
Some area codes cover a very large geographic area, up to an entire state.
Searching for a location near the center of a large area code may not find locations near the boundary of that area code. The exchange is the first three digits after the area code. You would enter 123-456 to search for locations nearest this exchange. An exchange usually covers a small geographical area, so it provides a more accurate location than its area code.
