.sx

.sx is the country-code top-level domain for Sint Maarten, the Dutch part of the Caribbean island of Saint Martin. IANA lists SX Registry SA B.V. as the ccTLD manager.

The two-letter ending can be useful for businesses, tourism projects, local organizations and services connected to Sint Maarten. It is also short enough to be used creatively by brands outside the territory, although that secondary branding does not change its status as a country-code domain.

For a locally focused project, the geographic signal can help make the intended market clear. For an international brand using .sx for its letters rather than the country association, it is worth considering whether visitors will understand the intended meaning.

The official .sx registration policy allows parties to request available names during general availability on a first-come, first-served basis, subject to registry rules. Reserved names, technical requirements and third-party rights can still affect availability.

As with other country-code domains, a registrant using .sx internationally should review current registry terms rather than assuming policies will always match those of a generic TLD.
