# The 658 Area Code

The 658 area code is an overlay area code serving Mississippi, specifically covering the same geographic region as the 601 area code. Established in 2014, the 658 area code was created to address the growing demand for telephone numbers in the state, as the original 601 area code was approaching exhaustion. An overlay area code means that both 601 and 658 serve the same territory, allowing telecommunications providers to issue new phone numbers with the 658 prefix while maintaining existing 601 numbers. This region includes Mississippi's capital and largest city, Jackson, along with surrounding communities and rural areas throughout the central part of the state.

The North American Numbering Plan (NANP) is the standardized system that designates area codes like 658 throughout North America, including the United States, Canada, and several Caribbean nations. Administered by the North American Numbering Plan Administrator, this system assigns three-digit area codes to geographic regions or service providers to organize the vast network of telephone numbers. When an area code becomes saturated with phone numbers, the NANP implements overlay codes like 658 to ensure continued availability of new numbers without requiring customers to change their existing phone numbers or service areas. This systematic approach has allowed the telecommunications infrastructure to accommodate population growth and increased communication demands across North America for decades.
