.sc is the Internet country code top-level domain (ccTLD) for Seychelles. The TLD was marketed to businesses in Scotland and the U.S. state of South Carolina, however, the domains are subject to Seychelles registry rules. While SCregistrars, a company who marketed .sc domains to a target audience of Scottish sites, has since closed down the .sc extension remains available through the Afilias Global platform via various well-known registrars internationally for direct registration at second-level.
