Area code 513

Area code 513 serves Ohio, including Cincinnati, Hamilton and Middletown (Eastern time). It has been in service since January 1, 1947 and shares its area with 283.

Numbers starting with 513 drew 2,153 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 894 complaints to the FCC since November 2023. The number on your screen can be faked, so a 513 number proves nothing about where a call came from.
