= Telephone number pooling
{wiki=Telephone_number_pooling}
Telephone number pooling is a regulatory practice used to conserve the supply of telephone numbers, particularly in areas where the demand for new numbers is high. Traditionally, telephone numbers were assigned to telecommunication providers (such as local exchange carriers) in blocks of 10,000 numbers. This approach often led to inefficiencies, where service providers might have large blocks of unused numbers due to varying customer demand.
