In the context of Enhanced 911, ANI stands for what?

• A. Automatic Location Identification
• B. Automatic Number Identification
• C. Automatic Network Identification
• D. Address Number Identification

Answer: (B)

In Enhanced 911, ANI stands for Automatic Number Identification. This is the system’s way of automatically providing the caller’s phone number to the dispatcher. Having the caller’s number lets responders identify who is calling and, when linked with the location data, trace back to the address associated with that number. The related concept used for showing where the caller is located is Automatic Location Identification (ALI), not ANI. The other terms don’t fit the role of identifying the telephone line in E911.
