Geo-targeting may be used in combination with wireless alert capabilities to provide alerts to a more granulated geographical area. Disclosed herein is a system and method for performing geo-targeting for various alert areas such that emergency messages may be delivered to mobile and static devices of different types in a localized area. In an example embodiment, geo-targeting supports the delivery area for wireless emergency alerts by identifying the cell sites that are in a specified geographic area that have technology capable of delivering wireless emergency alerts. The components of the telecommunications system that support a wireless emergency alert system may be identified and mapped to any geographical area. The method and system of geo-target mapping may provide an efficient and more robust way of determining the telecommunication components to be employed for broadcasting emergency alerts.
