Find any 601- phone number in Mississippi

The 601 area code is the telephone area code for Mississippi. It is the second of two area codes for Mississippi, the other being 228. This area code was created in March of 1999 as an overlay for Mississippi, when the phone lines that previously serviced the state with the area code 601 became exhausted. The 601 area code also serves three counties in Louisiana.

The system that designates the 601 area code is the North American Numbering Plan (NANP). The NANP is an international numbering plan that organizes phone numbers in North America into structures made up of 3-digit area codes, and 7-digit local numbers. The NANP is administered by the North American Numbering Plan Administration and is shared by the United States, Canada, and some Caribbean and Pacific nations. The NANP is used to create phone numbers within services like landlines, cell phones, and VoIP, and to enable cross-border and international calls.
