North American area code 513 serves southwest Ohio including Cincinnati and many surrounding cities, such as Forest Park, Hamilton, Lebanon, West Chester, Mason, Middletown, Norwood, Oxford, Harrison, Cleves, Miamitown and Trenton. It is one of the original area codes established in 1947, and originally covered the entire southwest quadrant of the state. In 1996, however, most of the northern and eastern portion of the old 513 territory, including Dayton, was split into area code 937.
Parts of area code 513 are long distance from Cincinnati depending on the prefix (for example, calls to Middletown). Area code 513 also has a large quantity of numbers belonging to people living in southeastern Indiana and Northern Kentucky due to the usage of cell phones.
