ANI (Automatic Number Identification)

ANI, or Automatic Number Identification, is a telephone service feature that automatically displays the caller's phone number to the recipient before the call is answered. It enables businesses and service providers to identify who is calling, often for purposes like call routing, billing, or security. Unlike caller ID, which can sometimes be blocked or unavailable, ANI is primarily used in telecommunications networks for accurate caller identification, especially in emergency services, toll-free numbers, and corporate environments, helping ensure efficient call management and improving overall communication reliability.
