Non-Emergency Numbers
9-1-1 (nine-one-one) is for reporting emergency events only. Law Enforcement, fire, and medical resources will be sent out directly when there is an immediate threat to life or property.
If you are unsure about what you are reporting is an emergency, call 9-1-1 and assistance will be dispatched to the most critical situations first.
9-1-1 should also be called when there is a good chance of arresting a crime suspect or preventing the development of a serious crime situation by reporting suspicious persons, vehicles, or circumstances, threats of violence or injury, escalating disturbances or actions which if not controlled quickly could lead to an emergency.

The Sheriff's Dispatch Bureau is the primary answering point for 9-1-1 calls within the unincorporated areas of Sonoma County, the Town of Windsor and the City of Sonoma. 9-1-1 calls for law enforcement are processed on-site. Fire and/or Ambulance assistance will be quickly routed on to the appropriate dispatch center of jurisdiction.
9-1-1 calls from land line phones are automatically sent to the emergency dispatch center via dedicated phone lines and receive priority answering. A database display linked to 9-1-1 calls shows caller location and phone number information to the 9-1-1 dispatcher. Calls requesting fire/medical support will be transferred promptly to the appropriate dispatch facility of jurisdiction, along with the accompanying 9-1-1 data display. The 9-1-1 dispatcher will remain on the line until communication has been established with the receiving dispatch center. If there is a situation where the caller hangs up, the 9-1-1 dispatcher will immediately provide the fire/medical dispatcher with the location and nature of the call.
Wireless 9-1-1 calls from cellular phones are initially received at the California Highway Patrol's (CHP) dispatch facility in Benicia, CA. The CHP dispatcher will route law enforcement calls for service to the Sheriff's dispatch center via dedicated phone lines.
Steps in Preparation for possible Emergency Situations |
|
|
Have the 9-1-1 number posted next to or on all telephones. |
|
Make sure your house number is displayed so that emergency resources can find your home. In an emergency, every second counts. Numbers should be displayed so that they do not blend into the house. Dark on light or light on dark works well. If you live off the roadway and/or have no mailbox, place a sign at the end or your driveway displaying your address information. If you live on a long driveway with many turns please display your house number at each turn or fork in the road. |
|
Know the nearest intersecting street to your address. This will help the operator provide directions to your location in cases of duplicate street names. |
|
Post a card with your address, family name and telephone number next to the telephone to assist children and visitors in providing that information in an emergency. |
