Area code 283 has been reserved as an overlay for area code 513, which serves southwestern Ohio, including Cincinnati and its suburbs. Though officially designated, 283 has not yet been implemented as of 2025 due to sufficient availability within the 513 code. When activated, 283 will cover the same region, which includes major employers such as Procter & Gamble, Kroger, and Fifth Third Bank. The Cincinnati metro area is a hub for consumer goods, healthcare, and logistics, and has a thriving arts and sports scene. Once live, a 283 number will represent new entrants into a stable and competitive market. For planning purposes, it’s important to be aware that future numbers in the Cincinnati area may be assigned with the 283 prefix, maintaining continuity across one of Ohio’s key economic centers.
