# Ohio Area Code 380

The 380 area code is an overlay area code that serves the Columbus, Ohio metropolitan region, operating alongside the established 614 area code. Implemented in 2018, the 380 area code was created to address the exhaustion of available phone numbers within the 614 code area. As Columbus experienced significant population growth and increased demand for phone numbers from businesses, residents, and mobile services, the North American Numbering Plan (NANP) designated 380 as a solution to expand the available number pool. Both area codes now service the same geographic region, allowing telecommunications companies to assign new numbers from either code to customers in the Columbus area.

The North American Numbering Plan is a standardized system that manages telephone numbering across North America, including the United States, Canada, and several Caribbean nations. Under this system, area codes are assigned to specific geographic regions and are managed by the North American Numbering Plan Administrator (NANPA) to ensure efficient distribution and prevent number depletion. When a single area code becomes saturated with numbers, overlay area codes like 380 are introduced rather than splitting the existing territory, a practice that eliminates the need for customers to change their phone numbers. This systematic approach ensures that the telecommunications infrastructure can accommodate growth while maintaining service continuity for existing customers in established regions like Columbus.
