Number Portability Industry Forum (NPIF) FAQs

What is the Number Portability Industry Forum (NPIF)?

Originally commissioned as a working group under the NANC (North American Numbering Council) the LNPA WG (Local Number Portability Administration Working Group) dealt with Number Portability issues and processes/procedures. In December 2018, it was renamed the TOSC (Transition Oversight Sub Committee) and dealt primarily with issues related to the transition of NPAC from the previous vendor to iconectiv.

After the re-chartering of the NANC, the group became The Informal LNP Team until November of 2020, when the group restructured into the Number Portability Industry Forum (NPIF). The NPIF works with the NAOWG (Number Administration Oversight Working Group) on any issues that require the involvement of NANC, and continues its mission to manage processes/procedures and issues related to Number Portability.
