An area code is a three digit code allocated to the different states of the United States of America. Assigning area codes is a part of the telephone numbering system. A “telephone numbering plan” is essentially about allocating numbers in a telephone network. An area code is assigned as per the technical aspects of the telecommunication network of a geographical region. The area codes indicate the areas within a country that fall under the network of numerous telephone exchanges.

These area codes are essential while making calls from outside the geographical boundaries of an area code or while making calls from a cell phone. While making any call, the area code is dialed after the national access code or the country code. Attributing different area codes to the different states makes it convenient to administer the telecommunication system.

Area code 313 was further broken down in December, 1997 and Washtenaw, Monroe and west Wayne County were put under area code 734.
