.si

.si is the country-code top-level domain for Slovenia and is operated by Register.si at ARNES. It provides a direct Slovenian identity for companies, organizations, services and personal projects.

Register.si describes the namespace as first-to-file: an available name can be registered without a general requirement that the holder be Slovenian or own a corresponding trademark. Trademark and other prior rights still matter, and the registry's terms prohibit registrations that infringe third-party rights.

The current verification framework also requires registrars to verify at least one contact channel, such as the holder's email address or telephone number, when a new domain is registered. This is a data-quality requirement rather than a Slovenian residency test.

The extension is especially natural for Slovenia-focused websites, while international registrants should remember that the country signal remains strong.

VYR classifies .si as open, subject to Register.si terms, contact verification, reserved names, dispute procedures and third-party rights.
