Telephone number distribution: a snapshot at the beginning of 2000

The United States is depleting its stock of telephone numbers for assignment to telecommunications carriers. If current trends continue the industry could run out of numbers as soon as 2015. There is little empirical examination of this problem in the economics literature. This analysis examines the distribution of telephone numbers across the United States and quantifies the effects of several key factors. The authors examine the effects that population density, competition for local telephone service, wireless telephone service provision and rate exchange area consolidation have on telephone number assignment.
