What system allows communication centers to receive location and number information on emergency calls?

The system that allows communication centers to receive location and number information on emergency calls is known as Automatic Number Identification (ANI) and Automatic Location Identification (ALI). ANI provides the phone number of the caller, enabling dispatchers to identify the individual making the call, while ALI provides the address associated with that number. This combination is critical in emergency situations, as it allows telecommunicators to quickly access essential information needed to dispatch emergency services to the correct location even when the caller may be unable to provide that information themselves.

This technology is foundational for effective emergency response, as immediate access to reliable caller information can significantly reduce response times and enhance the overall effectiveness of emergency services.
