Automatic Number Identification is the concept tested. It means the system automatically conveys the originating telephone number to the receiving end, allowing the caller’s number to be identified for routing, billing, and records. In emergency services, this number is used to look up location information in a separate database (Automatic Location Information) to help locate the caller, but ANI itself does not include the address or dispatch details. The option using a misnomer, “Automatic Number Information,” is not the standard term. The other choices describe location or dispatch data, which ANI does not provide.
