ANI vs. DNIS: Automatic Number Identification (ANI) vs. Dialed Number Information Service (DNIS)

Automatic Number Identification (ANI) is a telecommunication feature that identifies a caller’s phone number, allowing businesses to recognize incoming calls, route them properly, and track caller information in real time. It operates in the background as soon as a call is placed.

ANI was originally developed by telephone companies for billing purposes, call returns, and call tracking. Today, businesses use ANI to improve call management, recognize frequent or high-value callers, and ensure important calls reach the right department quickly. In call centers, ANI helps identify returning customers, allowing businesses to access customer records and provide personalized service promptly.

Dialed Number Information Service (DNIS) is a telephony feature that identifies the specific phone number a caller dialed to reach a recipient. It transmits information about the destination number, allowing the system to determine call-routing details. It means that when a call comes in, DNIS tells the business which of its numbers was dialed, helping direct the call appropriately. It also works with IVR systems to play customized greetings and menu options based on the dialed number.
