Champaign County Area to Add Additional Area Code



URBANA, OH, 07/10/19—The Dayton, Ohio area is expanding and getting a new area code. As the area’s number one provider for telephone service in Champaign County, CT Comm wants to make sure that local residents remain informed regarding the new change.


Area code 937 has covered Bellefontaine, Dayton, Fairborn, Hillsboro, Marysville, Preble County, Springfield, Wilmington, Urbana, Xenia, and areas north and east of Cincinnati since 1996. With Dayton, Ohio and surrounding areas expanding, the current area code is no longer able to accommodate the population’s need for unique number combinations. As a result, a new area code is being added: area code 326.


The new area code, which spells out “DAO” (as in Dayton, Ohio) on a traditional keypad, is scheduled to provide overlay for the 937 area by early 2020. On February 8, 2020, traditional seven-digit calling will no longer be available and callers will have to dial ten digits to make a call. The change is expected to take place in a series of steps, with completion anticipated for January, 2020.


Here is what local residents need to know*:

Your current telephone number will not change.

Calls currently considered local calls will remain local calls. Calls between 937 and 326 can be local calls.

911 and other three-digit numbers, when available, will not change (ie: 211, 311, 411, 811 etc.)


Since two area codes will now serve the region, customers within the 937/326 geography will need to dial the correct area code followed by the seven-digit phone number when dialing all local calls. Long-distance calls will still require the 1 + ten digit dialing.


A transition period is expected to begin August 10, 2019 with mandatory ten-digit and 11-digit dialing going into effect February 8, 2020. March 8, 2020 is the earliest date that new numbers will be activated using the new 326 area code.


CT Comm is available to answer any questions you might have regarding this upcoming transition. Please feel free to call our Champaign County office at (937) 653-4000, option zero for CT Comm Customer Service.
