Number Portability (NP) refers to the right of subscribers to change providers of electronic communications while retaining their telephone number. With NP subscribers do not need to change their numbers when they change providers of electronic communications. So, NP enhances competition in the market as providers try to attract to their network subscribers from other networks.
To facilitate the provision of number portability, a National Reference Database for Portability (NRDBP) has been implemented and operates under the supervision of the EETT. NRDBP includes information necessary for call routing and facilitate providers in dealing with number portability applications.
Number portability is available for both mobile and fixed telephony numbers.
