What information does ANI provide in a wireless E9-1-1 call?

The Automatic Number Identification (ANI) specifically provides the caller's phone number during a wireless E9-1-1 call. This information is crucial for emergency responders, as it allows them to contact the caller directly if necessary and helps to establish the identity of the caller.

In the context of a 911 call, this piece of information becomes vital, especially in situations where the caller may not be able to communicate effectively or is in distress. While other types of information, such as address details or geo-location, are useful for dispatching resources, the primary function of ANI is to relay the calling number. This ensures that emergency services can respond accurately and promptly to the emergency situation presented by the caller.
