Getting started
What is .si and who can register one?
What .si is, who can register it, which characters are allowed and who we are.
What is .si?
.si is the country-code top-level domain of Slovenia, run by the national registry, Register.si, which is part of ARNES (the Academic and Research Network of Slovenia).
Does .si officially mean superintelligence?
No. .si is Slovenia's country code and has no official connection to AI. The appeal is that “SI” is used as shorthand for superintelligence in AI circles, in the same way .ai (Anguilla's code) appeals to AI companies.
Who are you? Are you affiliated with the registry?
We are an independent reseller of .si domains. We are not affiliated with Register.si or ARNES, nor with any AI company. We register domains through the registrar platform Openprovider and take payment through Stripe.
Who can register a .si domain?
Individuals and companies. The registry's terms define a domain holder as a natural or legal person and do not require you to live in or be established in Slovenia. You must give accurate registrant details.
Which characters can I use?
Letters a-z, digits and hyphens, plus the Slovenian letters č, š and ž. The registry allows other Latin characters too, but we only accept these so that a name you pay for is not rejected afterwards.
How long does a registration last?
The registry allows registrations of one to five years. You can register or renew for 1, 2 or 3 years per purchase.
