History of the 405 Area Code
The 405 area code was established in 1947 as one of the original area codes under the North American Numbering Plan. Over the years, the demand for new numbers increased, leading to changes in the area code's structure. In 1997, area code 580 was created as a split from 405 to accommodate the growing need for additional phone numbers. This change was necessary to ensure that residents and businesses in the region could continue to receive new telephone numbers without interruption. For more historical details, visit the North American Numbering Plan Administrator (NANPA).
