The 380 area code is a recent addition to Ohio's telecommunications network, serving the Columbus area.


Introduction as an Overlay: The 380 area code was introduced as an overlay to the existing 614 area code. This implementation, which began on January 30, 2016, was designed to provide additional numbering resources in response to the high demand for telephone numbers in and around Columbus, Ohio. The overlay approach allowed existing 614 subscribers to retain their phone numbers, while new numbers could be assigned either the 614 or 380 area code.



Geographic Coverage: The 380 area code, along with the 614 area code, covers the Columbus metropolitan area and its surrounding suburbs. Columbus is the state capital and the largest city in Ohio, known for its diverse economy, including education, government, insurance, banking, defense, aviation, food, clothes, logistics, steel, energy, medical research, healthcare, hospitality, retail, and technology.



Adoption of Ten-Digit Dialing: With the introduction of the 380 overlay, ten-digit dialing (area code + phone number) became mandatory for all local calls within the 614 and 380 area codes. This requirement, aligning with the standard practice in regions with overlay area codes across the United States, was essential to manage the growing number of phone users and the increasing need for more telephone numbers in the region.


These facts about the 380 area code highlight its vital role in supporting the telecommunications needs of the Columbus area in Ohio. By providing additional numbering capacity and facilitating the transition to ten-digit dialing, the 380 area code ensures that the region's communication infrastructure can keep pace with its growth and evolving needs.
