About .sg domains

About .sg domains

.SG is a country-code top-level domain (ccTLD) in the DNS root zone. It is designated for Singapore. The IANA root zone lists the registry manager as Singapore Network Information Centre (SGNIC) Pte Ltd. Registration policies (who may register, local presence, pricing) are set by the registry and its accredited registrars — not by IANA.

.sg is the Internet country code top-level domain (ccTLD) for Singapore. It was first registered in September 1988. It is administered by the Singapore Network Information Centre (SGNIC). Registrations are processed via accredited registrars. In 2011, two new internationalized country code top-level domains were registered for Singapore, intended for domain names in the local languages. These domains are .新加坡 (encoded as .xn--yfro4i67o) for Chinese websites, and .சிங்கப்பூர் (encoded as .xn--clchc0ea0b2g2a9gcd), for Tamil websites.

Who can register .sg domains?

Eligibility is defined by the registry operator and its registrars. Most gTLDs are open to anyone worldwide. Many ccTLDs are also open globally; some require local presence, citizenship, or trademark rights. Always confirm current policy with the registry or your registrar.
