# Ohio Area Code 283
The 283 area code is an overlay area code serving the Columbus, Ohio metropolitan region, established to meet the growing demand for telephone numbers in central Ohio. Implemented in 2020, the 283 area code was created alongside the existing 614 area code, which has served the Columbus area since 1947. As an overlay code, the 283 area code covers the same geographic territory as 614, meaning both codes serve the same cities and regions, including Columbus, Westerville, Hilliard, and surrounding communities. This overlay system allows telecommunications providers to distribute new phone numbers more efficiently without requiring customers to change their existing numbers or area codes, providing flexibility for the region's continued growth and expansion.
The North American Numbering Plan (NANP) system designates area codes through a hierarchical structure managed by the North American Numbering Plan Administrator (NANPA), which operates under the jurisdiction of the Federal Communications Commission (FCC). Area codes are assigned based on projected demand for telephone numbers, geographic regions, and carrier requirements rather than political boundaries. When an area exhausts its available phone number resources, regulatory agencies authorize new area codes through overlay or split methods. The 283 overlay represents a modern approach to number management, allowing the Columbus region to accommodate new businesses, residents, and wireless devices without the disruption of a traditional area code split, which would have required some customers to adopt an entirely new area code.
