The Collin County Alert Network is a free service provided by the CitizenObserver organization through "tip411" to enable persons to receive alerts from the Sheriff's Office via e-mail or as a text message to a cell phone.

Through this website, The Collin County Sheriff's Office will provide information to help maintain and improve community safety. You can also opt to receive surrounding city and community alerts that are on the CitizenObserver alert system.
