Good morning, I am planning on doing a mass mailing searching for any Fitch surname connections in Harrison County. Yahoo has a directory listing and a lot of the listings have a 712 area code, for cities not even in Harrison County. Is this normal in Iowa to have the same area code for more than one county? Or is yahoo using 712 as a coverall number for what they have not researched maybe? Welcome all comments. Thank you, Deborah
