Toll Free Number Growth

The Number Administration Summary Report for the week ending Saturday, May 1, 2010, shows a total of 4,001,861 numbers remaining in the spare pool. The quantity of numbers in use increased by 175,891. Please see CSB NUM-10-18 for full details.

A statistical analysis performed in February 2010, relying on data from August 1997 to January 31, 2010, indicates the current pool of Toll Free numbers will exhaust in second quarter 2014. The forecast also indicates that the 90% threshold of the current pool, or 28,629,000 Toll Free numbers in use, will be reached in fourth quarter 2011. Toll Free number utilization will continue to be monitored and the forecast will be updated as required.
Toll Free number growth has risen significantly since the statistical forecast was conducted.  If usage continues at the same level as the average growth rate for the last six (6) weeks, the estimated exhaust date for the current Toll Free number pool is as follows:

(A) Total Spare Numbers  = 4,001,861
(B) Average Growth/Week  = 72,822
(C) Spare/Average Growth = 55 Weeks (estimated exhaust date of 05/14/11)
