.sg domain is Singapore’s country code Top-Level Domain and is managed by Singapore Network Information Center (SGNIC). The service was introduced in 1988 and has been active since then. The country had two ccTLDs that were meant for registration of domain names in Singapore’s local language.
SGNIC requires that the entity that is opting to register for the .sg domain should be a citizen of Singapore or be operational within the country if it is a company. This is because the main objective for introducing the domain was so that it can be used across the country. This regulation is sometimes seen as inappropriate and unnecessary because it is rare to find a company in, for example, Brazil registering a domain name with another country’s ccTLD.
