Area Code 326 Location

Area code 326 serves Dayton, Ohio and the broader Miami Valley in southwest Ohio as an overlay to area code 937. It was introduced in 2020 to add more phone number capacity without changing existing numbers, and both area codes cover the same geographic area. This means 10-digit dialing is required for local calls across the region, but calling areas and rates stayed the same. Dayton’s central role in aviation history—home of the Wright brothers—adds extra recognition to this area, with major employers and institutions anchored here.

Major cities and communities covered by the 326/937 overlay include:

• Dayton
• Springfield
• Kettering
• Beavercreek
• Huber Heights
• Fairborn
• Xenia
• Troy
• Piqua
• Sidney
• Miamisburg
• Centerville
• Greenville
• Wilmington These communities also connect to key landmarks like Wright-Patterson Air Force Base and the National Museum of the U.S. Air Force, one of the region’s biggest attractions.

The 326 overlay works alongside 937, which has served the area since 1996 after a split from 513, keeping local identity intact while expanding number availability. New lines may get a 326 phone number, while existing 937 numbers continue to work as before. As the Public Utilities Commission of Ohio notes, 10-digit dialing ensures a steady supply of numbers for residents and businesses. Fun fact: Ohio proudly promotes the area’s aviation roots with the slogan “Birthplace of Aviation” (State of Ohio), and much of that story centers on Dayton.
