A PLACE AND A POSSIBILITY

Why choose a .si domain?

.si is Slovenia's country-code domain, managed by Register.si at ARNES. It is a natural choice for a Slovenian business, a local service or a brand reaching customers in Slovenia.

For a technology project, the letters SI can also suggest super intelligence or superior intelligence. That is a creative branding connection, while .si remains Slovenia's national domain. Use a memorable name for your AI tool, software product or research project, with a matching email address such as hello@yourname.si.

A few things to know

Can I register a .si domain from outside Slovenia?

Yes. Individuals and organisations can register .si domains without being based in Slovenia. Provide accurate registrant and contact details and choose a name that meets the registry's rules.

Does .si mean super intelligence?

Officially, .si is the country-code domain for Slovenia. Super intelligence and superior intelligence share the initials SI, making them possible branding associations for an AI project. A .si registration does not certify a product's capabilities or imply official endorsement.

How do I register a .si domain?

Search for your preferred name above. If it is available, choose one of the offered registration periods and complete your order. The available-name list can help you explore alternatives.

Which registration periods are available?

The registry allows registration and renewal for one to five years. Open the pricing table above to see the periods offered through ISTanCo and their total prices.

Can I transfer an existing .si domain?

Yes. Arrange an AuthInfo transfer code with your current registrar and provide it when using our domain transfer form. Changing registrar does not extend the registration period, so check your expiry date separately. Contact us if you need help.

Can I use .si for a website and email?

Yes. Your domain can be the address for your website and for email such as hello@yourname.si. Website and email hosting are separate services: explore our web hosting and email hosting options.
