This document specifies guidelines for the assignment of NXX codes within the 9YY Service Access Code (SAC) to carriers. These guidelines are provided to accommodate a method which utilizes unique NXX codes within the 9YY SAC to identify individual carriers in order to allow multiple carrier 9YY access. This method requires a Local Exchange Carrier (LEC) to 6-digit translate the 9YY NXX portion of a 9YY-NXX-XXXX number in order to identify the carrier for call routing.
