3 CO/NXX WORKSHOP ORPHANED CODES INC finished documenting procedures for NANPA, the PA, and SPs to follow when codes with ported out TNs are returned or abandoned. These procedures, contained in separate appendices, support the interim FCC direction that was provided to NANPA and the PA.

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.
