# Area Code 659: Mississippi's Growing Communication Hub

Area code 659 is a relatively recent addition to the North American Numbering Plan (NANP), established in 2014 to serve central Mississippi. This area code was created as an overlay to the existing 601 area code, meaning both codes serve the same geographic region, which includes the state capital of Jackson and surrounding communities. The overlay system allows telecommunications companies to issue new phone numbers without requiring customers to change their existing numbers, thus reducing disruption while accommodating the region's growing demand for telephone lines driven by population growth and increased business activity.

The North American Numbering Plan is a standardized system that organizes telephone numbers across North America, including the United States, Canada, and several other territories. Developed in 1947, the NANP assigns three-digit area codes to geographic regions, with each area code followed by a seven-digit local number. When an area code becomes saturated with available numbers, regulatory bodies like the North American Numbering Council evaluate options including overlays like 659, or creating entirely new area codes for different regions. This system ensures efficient management of the finite supply of telephone numbers while maintaining the infrastructure necessary for modern telecommunications across the continent.
