Number Pooling in Exchange (608) 564
The initial set up of an Exchange was to have all 10,000 numbers (0000 - 9999) for a particular Rate Center allocated to the same local exhange carrier. With the advent of multiple carriers, allocating each one of them their own Exchange Code would be inefficient and soon use up the available number pools for a particular area. To counter this, some exchanges are split into blocks of 1,000 numbers, which can each be allocated to individual carriers. This cuts down on wasted numbers that aren't allocated as each carrier has a smaller pool available.Number Pooling is activated in Exchange 608-564 and the following thousand blocks are currently assigned to carriers.
