The LNPA WG (Local Number Portability Administration Working Group) is a subcommittee of the NANC (North American Numbering Council), an advisory body to the FCC (Federal Communications Commission).  The LNPA WG was formed at the behest of the FCC to develop technical requirements for the centralized data base approach to local number portability.

Neustar is the NPAC Administrator for Canada.

Neustar is no longer the Local Number Portability Administrator for the United States. If you are a Law Enforcement or Public Safety agency in the U.S. and need access to look up telephone numbers, please contact the current administrator – iconectiv – at https://lawenforcement.numberportability.com/.

If you are an entity that needs to register as a phone carrier or provider of telecommunications related services for the United States, please contact iconectiv at 844-820-8039. Thank you.

The primary responsibilities of the NPAC include:

•  Data Administration: Ported telephone number data administration, service provider network data administration and audit administration
•  Mass Changes: Area code (NPA) splits and LRN transfers
•  Billing and Cost Appointment

• LNP allows a consumer to keep their current telephone number (TN) when moving to another local communications service provider (both the old service provider and new service provider must be LNP-capable).  The service arrangement using the TN at the new SP is associated with same rate area as was the service arrangement at the old communications service provider.

• LNP allows a wireline communications service provider to offer services, such as foreign wire center (aka "soft FX"), through switch translations when the service offering formerly required physical extension of the customer's loop.

• LNP increases competition among local communications service providers.

LNP was introduced to further increase competition in the local telephone service arena. Studies indicated increased consumer willingness to change communications service providers if their telephone numbers could be retained.
