This page is intended as a dedicated resource for regulatory documents relating to Geographic Number Portability (GNP), which was fully implemented in South Africa on 26 April 2010. From this date it became possible to port a single number from one provider to another (previously only blocks of 1 000 or more numbers could be ported).
GNP allows consumers to switch fixed line service providers while retaining their fixed line (or geographic) telephone number. It is an important pro-competitive regulatory intervention in that it allows new entrants into the fixed line market – most obviously VoIP providers – to gain market share. Up until the introduction of GNP the inability of a consumer to retain their number(s) when changing providers constituted a major obstacle to taking advantage of better priced offers due to the associated costs and inconveniences of changing number(s).
When you hear three (3) beeps while making a call, it means that the number you are calling is a ported number.
