Document Name:  D Digit Report
Document Date:  January, 2003
Document Number:  ATIS-0300073
Document Version:  1/24/2003
Committee:  INC
Collaborating Forum(s): 
Document Type:  Guidelines
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.
