That is why Europe Commission decided to include number portability in a universal services directive as a required service to be implemented in all member countries.

    • Updated network may be able to provide new services
    • Lowering barriers to new entrants to market
    • Levelling playing field for existing market
    • Eliminating another barrier for fair competition
    • Raising customer satisfaction
    • Optimise numbering resource usage
