Access the NPAC

The NPAC contains the proprietary data of competing communications service providers. Given the critical and sensitive nature of this data entrusted to the NPAC by competitors working together to make LNP work, access to the NPAC and usage of NPAC data is strictly defined and limited to specific, permitted uses.

Service providers and providers of telecommunications-related services are the only users permitted to access and/or use NPAC data for the exclusive purpose of routing, rating, or billing of calls, or for performing network maintenance in connection with the provision of telecommunications-related services.
