SGNIC was formed in October 1995 with the main purpose of administering the Internet domain name space in Singapore as well as to provide a forum for the local Internet Service Providers and regulatory bodies to discuss issues related to the efficient administration of internet services in Singapore

In June 1997, SGNIC was incorporated as a private limited company, wholly-owned by the National Computer Board (NCB).  SGNIC was subsequently transferred to the Infocomm Development Authority of Singapore (IDA) when the government merged the NCB and the Telecommunication Authority of Singapore on 1 December 1999.

Today, SGNIC is the appointed national registry responsible for authorising and regulating the registration, administration and management of domain name ending with the .SG Country Code Top Level Domain (ccTLD).
