• A. Automatic Location Identification (ALI)
• B. Emergency Service Number (ESN)
• C. Geographical Information Systems (GIS)
• D. Automatic Number Identification (ANI)

Answer: (D)

The key idea is recognizing what Automatic Number Identification (ANI) actually represents. ANI is the telephone number information of a 911 caller. This number is what identifies and can be used to call back the person who placed the call, which is essential for initial contact and, in many systems, for routing the call to the appropriate PSAP. Understanding the other terms helps confirm why ANI is the right match here: Automatic Location Identification provides the caller’s location or address, not the phone number itself. The Emergency Service Number is a routing code used in some systems to identify the type of service or the PSAP region. Geographical Information Systems are mapping tools that help display data like locations and other spatial information, rather than the caller’s phone number. So, the term that corresponds to the telephone number information of a 911 caller is Automatic Number Identification.
