Dialed Number Identification Service. Dialed Number Identification Service (DNIS) is a service sold by telecommunications companies to corporate clients that lets them determine which telephone number was dialed by a customer. This is useful in determining how to answer an inbound call. The telephone company sends a DNIS number to the client phone system during the call setup. The DNIS number is typically 4 to 10 digits in length. Any DID (Direct inward dial) number will have a DNIS. This is the number sent from the central office to the PBX (Private branch exchange) or key system, telling the telephone system which number was dialed.
