4. 4 LNPA WORKSHOP Number Portability and Pooling are at a rate center level Some local calling plans (e.g., Extended Area Service) have different boundaries than rate centers Some states define rate districts within rate centers as wireline call rating mechanisms Calling Party call rating for all customers is impacted by the above two points Different districts/plans are served by distinct NXXs Therefore, states with different districts/plans should require separate pools within the same rate center Numbering resources for distinct districts/plans may need to be considered separately for code and block acquisition.
