Area code 283

Area code 283 serves Ohio, including Cincinnati, Hamilton and Clermont (Eastern time). It has been in service since April 28, 2023 and shares its area with 513.

Numbers starting with 283 drew 148 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 52 complaints to the FCC since November 2023. The number on your screen can be faked, so a 283 number proves nothing about where a call came from.

Phone companies holding 283 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
