About This Item

 

Full Description

Reissued with the resolution of Issue 680.

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.
