.sx Domain: Sint Maarten's Official Country Extension
.sx is the country code top-level domain of Sint Maarten and entered the root zone on 20 December 2010. Sint Maarten is a constituent country within the Kingdom of the Netherlands and covers the southern half of the island of Saint Martin. The zone belongs to SX Registry SA B.V., a company seated on the island whose technical operations run on CIRA in Canada and whose management sits in Luxembourg. The extension opened to the world on 15 November 2012, taking over from the retired .an domain. The registry accepts no direct applications; you register through an accredited registrar.
There is no eligibility test on .sx, and the registry says so in its own launch announcement: it places the extension among «open» registries alongside .de, .us and .co, and states that no local presence on the island is required. You do not need to live there, hold a company there or file any document; individuals and organisations register on identical terms, and priority goes purely to whoever applies first. The only limit lies in the name itself: names reserved for the Government of Sint Maarten and public bodies, and names on the registry's premium list, are closed to general registration.
Two details matter once the name is yours. The first is privacy: the registry's whois output publishes only the holder's organisation and country and masks the name, street, phone and email fields, so registering as a private individual leaves no personal data in public. The second is the dispute route: the policy channels every domain dispute to a single arbitration body, the Czech Arbitration Court, and freezes any transfer while proceedings run. Find out whether the name you want is still free on the domain name search page.

.sx Domain Lifecycle
What happens day by day after it expires
Day 0 is the domain's expiry dateIn short: for .sx the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .sx, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.
Domain Is Available (Available)
A .sx address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.
Domain Is Active (Active Period)
Once registration is complete, the domain is registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.
Redemption Period (Redemption Period)
The domain is not released the moment it expires — during this window it is still yours and can be recovered. Some extensions charge an extra restore fee at this stage, so renewing before expiry is always the cheaper route.
Pending Delete Period (Pending Delete Period)
If the redemption window is missed too, the domain enters the final stage and waits to be deleted. Renewal and recovery are no longer possible here; when the period ends the registration is removed for good.
Domain Is Available Again
Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .sx Domains
The questions people actually ask before registering — answered plainly.
-
No. The registry's own question page puts it plainly: every natural person or organisation may register its .sx domain names, and an address on the island of Sint Maarten is not required. An individual living in Türkiye and a company incorporated there apply on exactly the same terms. There is no local address, local contact or trustee requirement, and no commercial register extract or identity document is asked for. The only compulsory intermediary is an accredited registrar: the registry takes no direct applications and processes a registration only through an authorised company. Names are allocated first come, first served.
-
Between one and ten years, in whole years. The policy requires whoever registers or renews the name to choose the number of years and sets the ceiling at ten. The term starts on the day of registration and ends on the same day of that month, so your expiry follows your own anniversary rather than the calendar year. You may renew at any point before the term runs out. One more detail is worth knowing: if the holder of the domain changes, the current term is extended by one year, subject to the ten-year ceiling.
-
You get eighty days in total, but the three stages differ sharply. When the term ends a forty-five-day grace period starts: the name is renewed automatically and stays active, so your site and email are not cut off. A thirty-day redemption period follows, during which the name stops working and recovering it costs a restore fee on top of the renewal. The last link is a five-day pending delete period; no operation is possible, and at the end the name is purged and opens to anyone. The registry is not obliged to warn you beforehand, so put the date in your own calendar.
-
There are two separate operations. For a change of registrar you appoint the new company, it notifies the registry, and the registry emails you an authorisation code directly. If you do not confirm within seven days a reminder follows with a further seven-day window, and failing that the request is cancelled automatically. This is why the email address held by the registry must be working. For a change of holder both the transferor and the transferee confirm, and once the move completes the registration term is extended by one year. Start on the domain transfer page.
-
Largely, no. In the registry's whois output the name, street, city, postal code, telephone and fax fields of the registrant, admin, technical and billing contacts all come back marked as redacted for privacy, and instead of an address the email line prints a fixed sentence pointing you to the registrar. Exactly two fields are published: the registrant's organisation and country. In practice that means a name held by a company shows the company, while a name held by a private individual has no organisation to show and leaves no personal data public. Check yours on the whois search page.
-
At a single arbitration body. The policy states that every domain name holder accepts that any proceeding concerning the name is conducted before the Czech Arbitration Court, applying ICANN's uniform domain name dispute resolution policy and the rapid suspension procedure. That separates the extension from many generic ones, where a complainant can pick among several approved providers; here the route leads to one institution. The holder also undertakes to take part in good faith. One consequence matters commercially: while proceedings run the name cannot be transferred, and a transfer becomes possible only after the decision.
-
No. The policy states that a .sx name may consist only of the letters a-z, the digits 0-9 and the hyphen, so accented characters and any non-Latin script are refused. The hyphen has its own rules: a name may not begin or end with one, and it may not carry two consecutive hyphens in the third and fourth positions — that last rule closes off the position the punycode prefix occupies. The registry has also published no language table in IANA's repository of internationalised domain name tables. A name in another script therefore has to be written out in Latin letters.
-
The extension was born together with a country. On 10 October 2010 the Netherlands Antilles were dissolved and Sint Maarten became a constituent country within the Kingdom of the Netherlands, on equal footing with Aruba and Curaçao; the island was assigned the ISO country code SX, and .sx entered the root zone on 20 December of the same year. It took over from the Netherlands Antilles address .an, and the handover was written into the rules: holders of .an names resident on the island were given a priority window to claim the matching .sx name. After trademark, local priority and land rush stages the zone opened to the world on 15 November 2012.
