Registration

.COM.SG

.COM.SG domains can only be registered for companies. Admin-c have to be an individual.

Companys or individuals located in Singapore have to state an additional parameter to register a .SG and .COM.SG domains:

X-SG-RCBID = <TEXT>
X-ADMIN-IDNUMBER = <TEXT>

Special SG transfer procedure

Additionally to the authorizationcode, the registry requires that the current contact information of the domain will be submitted with the transfer request. To do so, you have to use the ownercontact0, admincontact0, techcontact0 and billingcontact0 parameters in the following syntax:

command = TransferDomain
domain = <domain>
auth = <auth>
ownercontact0 = <contact handle>
admincontact0 = <contact handle>
techcontact0 = <contact handle>
billingcontact0 = <contact handle>

Be sure that you've created valid contact handles with the current contact information of the .SG domain you wish to transfer the respective domain. After 7 days, the registry will reject the transfer if the losing registrar did not react.

Several registrars also need a so called AGNT number before they will approve an outgoing transfer, our AGNT number is AGNT-1643.

Deletion

To delete a .SG domain please contact our support team at [email protected].

Ownerchange

The current registrant will receive an email by NIC.sg, which must be approved for the changes to take effect.
