Domain .sx - national domain: Sint Maarten

Domain .sx — Sint Maarten, in two memorable letters

.sx is the country code top-level domain (ccTLD) for Sint Maarten. A ccTLD is the two-letter extension assigned to a country or territory — like .pl for Poland. .sx is open to everyone with no restrictions, and because it's just two letters, it works equally well as a local Caribbean identity or as a short, brandable address for any business.

What is a .sx domain used for?

.sx has two clear strengths. As a local extension, it's perfect for businesses operating in or serving Sint Maarten:

• travel agencies and tour operators
• restaurants, bars, and hospitality
• hotels, villas, and holiday rentals
• local shops and service providers

As a short, brandable extension, it appeals far beyond the island — much like .io or .co. Two letters make for compact, easy-to-type names, so .sx is also a smart pick for tech products, startups, and creative domain hacks.

Are there any restrictions to registering an .sx domain?

Everyone. .sx has no registration restrictions, so you don't need to prove a location or business type. Registration is processed in real time, which means your domain is active right after you complete your order — no waiting period.
