This INC Interim NANP Expansion Report documents the status, as of year end 1999, of the North American industry's efforts to establish a NANP expansion plan. In this report the INC has identified five options for further analysis and evaluation. These five options are described in detail in this report. The INC's objective is to select a single option for recommendation to NANP area national regulatory authorities for final approval. Two major assumptions regarding use of the INC Uniform Dialing Plan and release of the D digit have been highlighted and national regulators have been urged to comment on these two assumptions.
