Alert Rockville
Rockville residents can be notified instantly of a variety of emergency situations through the Alert Rockville program. Residents must sign up for Alert Rockville, which will send emergency alerts as e-mails that go to their computers or as text messages delivered to their cell phones, as messages sent to personal electronic communication devices such as pagers or BlackBerrys. The system is free for users.

Reverse 911
Reverse 911 is a separate operation from Alert Rockville, but is just as vital. Reverse 911 allows contact of citizens and/or businesses via telephone to inform them of urgent situations. Citizens must sign up to be part of the Alert Rockville notification system. Participation in the Reverse 911 is automatic for all phone users.

Reverse 911 operates through a database of City of Rockville phone numbers provided by the local telephone company. Damage from hurricanes and other extreme weather conditions, fires, hazardous chemical spills, public water supply concerns and serious criminal investigations (i.e., searches for suspects, missing children, etc.) are examples of when a Reverse 911 alert phone call may be made to citizens in an affected City neighborhood or throughout the entire City.
