In the case of emergencies such as severe weather or other public hazard, Calloway County uses a "reverse 911" system to notify residents. However, more and more people are now using their cell phones as a primary point of contact and may not have (or often answer) landline telephones. In an effort to include all residents should an emergency arise, the county has partnered with the One Call Now system.
