The SX Registry
The registry of the .SX Top Level Domain (TLD) is managed by SX Registry SA.
SX Registry promotes the usage and the registration of .SX domain names on a national and an international level via attractive Registrar packages and a dedicated Marketing program.
Truly global, the Registry is based on the island of Sint Maarten with technical operations performed by CIRA in Canada, and management in Luxembourg.
Registrars are accredited organizations that are allowed access to the automated system of the .SX registry in order to register Domain Names for their customers or themselves.
SX Domain Names can only be registered via Registrars that are accredited with SX Registry. A full list of Registrars with whom .SX Domain Names can be registered is viewable
