Who can register a .SX domain?
Anyone. There is no residency, citizenship or local company requirement, so individuals and businesses anywhere in the world can register a .SX domain.

Until October 31, 2026, a new one-year .SX registration is $22.75 USD for the first year. After that, registration is $30.00 USD per year. Renewals are $24.00 USD per year and transfers are $20.00 USD, which includes a one-year extension. Prices exclude applicable tax.

Is WHOIS privacy included?
Yes. Every .SX domain registered with AnyKey SX is set to private at the registry free of charge, so your personal contact details are not shown in public WHOIS lookups.
What names are allowed?
A .SX name can be 3 to 63 characters long and use letters a to z, numbers 0 to 9 and hyphens. It cannot start or end with a hyphen.
How long can I register a .SX domain for?
From 1 to 10 years at a time. You can turn on auto-renew in your client area so your domain never lapses.
Can I transfer my .SX domain to AnyKey SX?
Yes. Unlock the domain at your current registrar, get its authorization (EPP) code and start the transfer on our domain transfer page. A domain cannot be transferred within 60 days of a previous transfer, or while it is in a redemption or pending-delete state. The transfer adds one year to your registration and does not change who owns the domain.
What happens if my .SX domain expires?
After expiry there is a 15-day grace period in which you can still renew, with a late fee. After that the domain enters a 30-day redemption period, when it can only be restored for a higher restore fee. If it is not restored, it is deleted and becomes available to anyone.
Can I use my own nameservers or DNS hosting?
Yes. Use AnyKey SX nameservers, or point your .SX domain at any other DNS provider or host from your client area.
Does .SX support DNSSEC?
Yes, the .SX registry supports DNSSEC. Contact our support team and we will help you add your DS records.
Is .SX good for SEO?
Google treats .SX like any other country-code domain, and it is a strong signal for customers in Sint Maarten. Search engines rank your site on its content and links, so a short, memorable .SX name plus a good website is a solid foundation.
