FAQ About Calling 911 | 911.gov

When you call 911 from a mobile phone, the call often lands in a regional center. A call-taker in a far-away city or county may answer. In this case, you'll need to supply some important information.

Before they can dispatch help, there are two pieces of information the call-taker needs to know immediately:

1. The city you're calling from
2. The type of emergency you have (police, fire, or ambulance)

Different emergency services use different dispatch centers. Once they have the information they need the call-taker can transfer you to the correct center.

Please remember regional area changes or differences in First Responders/Fire Departments could vary some of the information in these Articles; however, they do still include helpful information:
