DOT SG Domains are the Top Level Domains of Singapore. These are domains ending with SG. The DOT SG Domains of interest to the public are Dot.Com.SG, Dot.Org.SG, Dot.SG and Per.SG.

SG Domains are not freely registered like for eg International Top Level Domains. There are rules which differ according to which extensions you are registering for.

Specific Rules for SG Domains

1.   DOT SG is the least restrictive for registration. Anyone can apply for Dot SG Domains. However applicants who are not resident in Singapore must appoint a local agent having a valid Singapore postal address as the Administrative Contact for the domain name, who shall also be authorized to receive all communications from SGNIC relating to the application.

2.   DOT COM.SG is for commercial entities registered in Singapore. A foreign company can only register such a domain name if it appoints a locally registered entity as its administrative contact. The foreign Registrant is required to submit a duly authorised letter to confirm the appointment of the locally registered entity.
