Exhaust date

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 buying more devices (e.g. cellular phones) needing dedicated phone numbers.
