The SCP NPA-NXX List (NXX) page allows an Administrator to view the list of NXXs that are supported by a given SCP pair for a specific NPA. In addition, an Administrator can control the calls to be handled by each SCP pair within their Common Channel Signaling (CCS) Network by creating SCP NPA-NXX Lists. Responsible Organization (Resp Org) users are not permitted to view the NXX page, unless their role is an SCP Administrator role.
All users having permissions for the NXX page can view, create, update, copy, and delete NXX Lists. In addition, an Administrator can remove an entire NPA from the Master Number List for a user-specified SCP pair.
To access the NXX page from the TFNRegistry™'s Landing page or from any page, select the Menu icon (in the upper left corner), the SCP Administration menu item and then the “SCP NPA-NXX List (NXX) sub-menu item. Once the "SCP NPA-NXX List (NXX)" sub-menu item has been selected, the sub-menu item will be highlighted and the NXX page will be displayed.
Please Note: If you do not have permissions to the SID page within the Network and SCP Administration menu, the SID page will not be available to you. If you need permission to the SID page, you must contact your Resp Org's Primary Contact or Company Administrator(s) for assistance. SCP Administrators can add, modify and delete SCP information within their own network.
