In telecommunications, an exhaust date refers to the date at which an area code will run out of numbers due to growth in the number of subscribers.
Projected exhaust dates have been moved up in recent years as population growth has been augmented by subscribers purchasing more devices (e.g. cellular phones) requiring dedicated phone numbers.
Famous quotes containing the words exhaust and/or date:
“Language is like soil. However rich, it is subject to erosion, and its fertility is constantly threatened by uses that exhaust its vitality. It needs constant re-invigoration if it is not to become arid and sterile.”
—Elizabeth Drew (1887–1965)
“There is nothing that I shudder at more than the idea of a separation of the Union. Should such an event ever happen, which I fervently pray God to avert, from that date I view our liberty gone.”
—Andrew Jackson (1767–1845)
