How to Call and Use 911

If you are calling from a business, provide the name of the business along with the suite number if there is one.

3. Name & Address Give your name and address. If your address is different from the location of the crime, be sure to let the dispatcher know. Dispatchers will verify your address and telephone to ensure that the telephone company address that is sent with the call is current and accurate. People living in mobile home parks, condominiums or on private roads, often have addresses that differ from the telephone company street.

Calling from a CELL - WIRELESS - MOBILE Phone
The California Highway Patrol (CHP) has jurisdiction over cell phone repeaters on or near freeways and highways. If you are calling 911 and you are near a freeway or highway, it is likely the call will be answered by CHP dispatchers. If the area given is not covered by the CHP, they will transfer you to the correct public safety agency. Follow steps 1 thru 6 above.
Calling from VoIP (Voice over Internet Protocol)
VoIP uses an internet data connection to connect a standard telephone device to another similar device, or to the public switched telephone system, in order to connect to any telephone in the world. To call 911 from VoIP, you must first arrange for E911service with the internet provider.
If the caller does not arrange for this service, they may not reach the appropriate dispatch center or have their address and phone number displayed for the call taker. Follow steps 1 thru 6 above.
