Abstract:  An underlying assumption in INC’s work on the expansion of the NANP has been the release of the D digit coincident with NANP expansion. This is necessary to effect a transition in which both the existing and the expanded numbers can be dialed by using the historic D digit as a trigger. Release of the D digit would permit any digit value from 0-9 to be used in that position. The objective of this report is to identify and investigate the technical impacts of D digit release.
