An automatic number announcement circuit (ANAC) is a special telephone number that is meant to be used by phone company technicians and other telecommunications technicians to determine the phone number of a particular line.
Calling this special number gives a pre-recorded announcement indicating the caller's own number.
The ANAC number is useful primarily during the installation of landline telephones to quickly identify one of multiple lines.

Famous quotes containing the words automatic, number, announcement and/or circuit:
“Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.”
—Richard Dawkins (b. 1941)
“In this world, which is so plainly the antechamber of another, there are no happy men. The true division of humanity is between those who live in light and those who live in darkness. Our aim must be to diminish the number of the latter and increase the number of the former. That is why we demand education and knowledge.”
—Victor Hugo (1802–1885)
“Losing faith in your own singularity is the start of wisdom, I suppose; also the first announcement of death.”
—Peter Conrad (b. 1948)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
—Robert Graves (1895–1985)
