Overview of Area Code 326
Area code 326 is a geographic North American Numbering Plan Area (NPA) code assigned to the state of Ohio, United States. It was introduced as an overlay for the southwestern portion of the state, serving the Dayton metropolitan area and surrounding communities. The overlay was implemented to address the exhaustion of numbering resources in the region, which was previously served by area codes 937 and 513. As an overlay, area code 326 does not require changes to existing telephone numbers; rather, it provides additional numbering capacity for new services.
Geographic Coverage and Administration
The 326 area code covers a significant portion of western and southwestern Ohio, including the cities of Dayton, Springfield, Kettering, Beavercreek, and Middletown. It also serves numerous smaller towns and rural areas within the counties of Montgomery, Greene, Clark, Warren, and parts of Miami, Preble, and Butler. The region is governed by the Public Utilities Commission of Ohio (PUCO) and administered under the North American Numbering Plan Administration (NANPA). The overlay was officially activated on [activation date], and all new telephone lines in the region are assigned numbers with the 326 area code.
Dialing Procedures
For local calls within the 326/937/513 overlay region, ten-digit dialing is mandatory. This means that even for calls between two numbers within the same area code, callers must dial the full 10-digit number (area code + seven-digit local number). For example, to call a business in Dayton from another local number, you would dial +1 326 555 0123 (or 326-555-0123). For international callers, the format is +1 326 XXX XXXX, where the plus sign indicates the international access code, followed by the country code 1, the area code 326, and the seven-digit subscriber number.
Overlay Considerations and Number Portability
As an overlay, area code 326 coexists with the existing area codes 937 and 513 in the same geographic region. This means that customers may have numbers from any of these area codes, and calls between them are considered local. Local calling areas are defined by rate centers, and no long-distance charges apply for calls within the local calling area. Additionally, number portability allows customers to retain their phone numbers when switching service providers, even if the new provider uses a different area code. However, when moving to a different geographic location, a new number with the appropriate area code may be required.
Caller Instructions
For callers within the United States, dialing a 326 number requires the area code and the seven-digit number. For example, to call a landline in Dayton, you would dial 326-555-0123. For international callers, dial your country's international access code (e.g., 011 from the US, 00 from many countries), then the country code 1, then the area code 326, and the seven-digit number. It is important to note that area code 326 is not a toll-free number; standard rates apply depending on your phone plan and the destination.
