Ohio 937 / 326 Area Code Overlay FAQs

General Information

  1. What is the Ohio 937 / 326 area code overlay?

    An overlay is the addition of another area code to the same geographic area as an existing area code. In Ohio, the 326 area code is being added to the area served by the 937 area code to ensure a continuing supply of phone numbers.

    You won't have to change your existing area code or phone number. However, because more than one area code will now serve the same geographic area, it does require you to dial or enter the area code and the 7-digit number for all calls, including calls within the same area code.

     

  2. Who's affected by the Ohio 937 / 326 area code overlay?

    Anyone who has a phone number with a 937 area code is affected, as well as anyone who receives a phone number from the 326 area code in the future. The 937 area code serves the west central portion of Ohio, serving communities such as Bellefontaine, Dayton, Greenville, Marysville, Springfield, Wilmington and Xenia.

    The 326 area code will cover the same geographic area as the 937 area code. The map below shows the 937 / 326 overlay area.



     

  3. What's the new calling procedure for customers with a 937 or 326 area code?

    The new 326 area code is being added to the geographic area served by the 937 area code. Because more than one area code will serve the same geographic area, if you have a 937 or 326 phone number, you'll need to enter the area code for all calls -- including calls within the same area code. To complete local calls from a phone with a 937 or 326 area code, the new calling procedure requires you to enter the area code and 7-digit phone number.

  4. When will the Ohio 937 / 326 area code overlay calling change begin?

    Beginning August 10, 2019, if you have a 937 area code, you should start entering the area code for all calls. There will be a grace period, so if you forget and enter just 7 digits during the grace period, your call will still be completed.

    Beginning February 8, 2020, if you have a 937 area code, the new calling procedure will be required for all calls. On and after this date, if you don't use the new calling procedure, your call won't be completed and a recording will instruct you to hang up and dial again, including the area code.

    Beginning March 8, 2020, new telephone lines or services may be assigned numbers with the 326 area code. If you have a 326 area code, you must enter the area code and 7-digit phone number on all calls or the call won't be completed.

     

  5. Will the Ohio 937 / 326 area code overlay affect my service?

    No, the only change is entering the area code for all calls. Your current area code and phone number won't change. The price of a call, your plan and coverage area, and other rates and services won't change because of the overlay. All local calls will remain local, regardless of the number of digits entered.

    • Calls that are considered local now will remain local calls, regardless of the number of digits entered
