.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. 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) and .சிங்கப்பூர் (encoded as .xn—clchc0ea0b2g2a9gcd).
