Buy your .si domain today

A .si domain is the country-code address of Slovenia, so it is the natural fit for businesses, organizations and creators who serve Slovenian customers. Local shops, tourism operators, startups and agencies can use it to show visitors right away that the site is built for Slovenia.

Since September 2026 it has also drawn AI teams and brand owners who read "SI" as shorthand for super intelligence. That group is newer, so check that your audience reads it the same way before you build a brand on it.

No, you do not need to live in Slovenia to register a .si domain. The registry's terms define a holder as any natural or legal person, with no nationality or residency condition.

Registration goes through an accredited registrar rather than with the registry directly, and you give your name, address and contact email during checkout.

A .si domain is officially Slovenia's country code, and since September 2026 it has also been bought as shorthand for super intelligence.

That second meaning is a trend rather than an industry standard, because the US executive order behind it covers federal agencies only. If your brand sits in AI, a .si works as an extra address beside your main domain, while .ai remains the extension the AI industry already uses.

A .si domain can rank outside Slovenia, but Google reads it as a signal that the site is meant for Slovenian users. Google treats country-code domains as a strong geographic signal and handles only a short list of them as generic, and .si is not on that list.

That works in your favor for a Slovenian audience. For a global audience, keep a .com or another generic domain as your main address and point the .si at it.

A .si domain makes more sense than a .com when most of your customers are in Slovenia and you want the address to say so. A .com is the stronger main address for a global audience, because it carries no country signal.

If you want both, register the .si, keep one address as primary and redirect the other to it. Update your email signature, social profiles and Google Business Profile to the primary address so visitors see one consistent name.

A .si dispute goes through the registry's own procedure, called ARDS, rather than the UDRP process used for many other extensions.

To win, you need to show rights recognized in Slovenia, such as a trademark valid there or a company name from the Slovenian court register, plus bad faith and no legitimate interest from the holder. If your brand has no Slovenian rights, registering the .si name yourself avoids that test.

A .si domain can be deleted by the registry if its contact email stops working or you lose access to it. The registry requires a valid address that you control directly, and it may delete the domain on its own initiative if you do not keep that address and your other details current.

Use a shared role address that will outlive any one person, and update your registrar whenever your details change.
