Administrator and Registry Operator of the Co.ZA, Net.ZA, Web.ZA, Org.ZA country code second level domains and the .Joburg, .CapeTown and .Durban Top Level Domains. The ZA Central Registry, formerly known as UniForum SA, was established as a non-profit organisation in 1988 by a group of end users, developers, and vendors who cooperated to form a professional association that would promote and exchange information on open systems. It was assigned the responsibility of administering the CO.ZA domain name space in 1995 because it was seen as not only having the technical skills and resources to do so, but also committed to neutrality and unity of purpose. At startup the co.za zone contained in the region of 400 entries. Today, with over 900 000 domains, amounting to over 95 % of the total registrations in the .ZA ccTLD, co.za ranks as a medium to large zone and within the top 30 registries world-wide in terms of size.
