Best Practices Document

Full Document: LNPA NP Best Practices Document

The members of the LNPA have created a "Best Practices" document for porting between and within telephony carriers. This document is NOT a mandate, but rather a gentleman's agreement on porting between carriers.

Please Note: All items from 1 - 44 were developed and agreed to by the WNPO (Wireless Number Portability Operations) team.
