This document describes the technical approach for the deployment of fixed number portability (FNP) service by the facilities based operators offering fixed line level 6 voice service.

** The FNP Guidelines, prepared by the existing fixed telephony service providers using level "6" numbers, describes the current implementation of FNP amongst these operators. Notwithstanding, new FBOs who intend to offer or will be offering fixed telephony service using level "6" numbers, are free to adopt the existing or any other workable alternative solution to implement FNP. Please contact the existing operators (via the contact information on page 4 of the FNP Guidelines) for more information.
