Understanding Ohio's overlay area codes
Some Ohio regions have multiple area codes because of overlay plans. An overlay adds a new area code to the same geographic area as an existing one, rather than splitting the region. For example, Columbus originally used only 614, but population growth and the demand for new phone numbers required the addition of the 380 overlay. This applies to every area code in the state, including 216, 614, 513, and 937.
How to use an Ohio area code
For long-distance calls within the United States to Ohio, dial 1, then the area code, then the number. No specific iPhone or Android menu path, app button, or carrier-specific step is required to use an Ohio area code, simply dial the number as described. For local calls within the 937 area code, you must include the area code even for local calls.
