The 937 area code was created in 1996 when it split from the 513 area code, which now serves only the Cincinnati metro area. The split was necessary to accommodate growing demand for phone numbers in southwestern Ohio.
In 2020, the 326 area code was added as an overlay to the same geographic region. Both 937 and 326 now serve the same area, so new phone lines may be assigned either area code. This means 10-digit dialing (area code + number) is required for all local calls. For regulatory details, visit the Public Utilities Commission of Ohio (PUCO).
The Miami Valley has a strong economic base driven by aerospace, defense, manufacturing, healthcare, and education:
