.SI domain policies

Shortcut to this article: opensrs.help/si
.SI is the country code TLD for Slovenia, and is regulated by the Register.si Registry, a part of ARNES (Academic and Research Network of Slovenia).

Registration details

Registration details can be found in the TLD reference chart.

Name server & DNS Requirements

In order to activate a .SI domain, you must provide at least two functional nameservers. The nameservers on the domain must be authoritative in the zone file. The SOA of the nameservers must match.

The DNS predelegation checks occur automatically every couple of hours. The domain name will be added to the DNS automatically once the configuration is correct.


All .SI domains are set to auto-renew by default.

Explicit renewals are allowed.

To allow a .SI domain to expire, auto-renew must be removed more than 2 days prior to expiry.  Domains that expire will be placed on ClientHold status and later deleted.

Deletion of a .SI domain can be done at any point by contacting OpenSRS. The domain will be placed in Pending Quarantine status for 30 days, after which it will be purged and dropped from the registry database.


Authcodes are required for all .SI transfers and can be obtained from the current registrar for the domain. The Authcode expires after 16 days. If you try to use an Authcode after it has expired, you will see a message saying that the Authcode is undefined. A new Authcode can be set using the Update API command.

Changes of ownership

Changing ownership of a .SI domain can be submitted via the Update API command. Ownership changes will not be charged and will not change the expiration date.

Trades are no longer required for .SI domains.
