SAC: Service Access Code
Service Access Code (SAC) refers to a code of the form "NO/lX" that takes the place of an NPA in the dialing sequence in order to access a particular service provided by an IC, BOC, or independent company. SACs currently in use include 700 (IC Services), 800 (800 Service), and 900 (National DIAL-IT* network communications service). SACs are associated with supplementary features that may be ordered by an IC as part of the access charge tariff. A BOC may screen calls and route to an IC-specified point of presence based upon a SAC dialed. There is no requirement that SACs be of the Form N00 nor that all N00 codes be SACs.
