Registering a Domain Name

Before registering a .si domain name, please consider reviewing General Terms and Conditions.

A domain name is a string of characters, chosen to your liking. Nevertheless, some restrictions apply:

  • A domain name cannot be alredy taken or reserved (link to the list of reserved domain names).
  • It should consist of valid characters only (link to the list of allowed characters).
  • A domain name cannot be less than 2 or more than 63 characters long in its textual and/or binary representation.
  • The first and the last character of a domain name cannot be hyphens ( e.g. “” in “”); nor can there be two consecutive hyphens in the third and the fourth position (e.g. “xx‐‐”).

A domain name registrar is an entity where you register domain names. Domain name registrars act as agents between end users (registrants) and registry operators.

Withdrawing from Contract (returning a domain name)

Every domain holder can cancel their domain within 16 days of registration.

Please note that you cannot not issue domain return once you have started to consume the service. In the particular case of domain name registration this means a return is not possible if the domain name has been activated*.

For a domain name to be eligible for return, domain status in WHOIS must be “inactive” and RGP status “Add Period”.

* – We (The Registry), consider a domain name activated as soon as the name server records have been submitted to our domain name activation systems.

Renewing a Domain Name

Anytime after registration and before the expiry of a 30-day quarantine period, you can request your registrar to renew your domain. If you do not know who serves as your registrar, you can find out by doing a WHOIS lookup. Domain names can be renewed for a period of one to five years.

Deleting a Domain Name

Your can delete your domain name anytime. The serving registrar will initiate the process at your request. Your domain name will be set a pending delete status and will remain in this status for 30 days, after which it will be purged and dropped from the registry database.

Updating Domain Name Information

As a domain name Registrant you are responsible for accuracy, completeness, currency, and integrity of information about your domain name. You can change or update the information anytime through your domain name registrar. A functional e-mail address is of paramount significance as it is the primary means of communication between a domain registrant (domain holder), registrar and the registry.

Caution – failure to establish an e-mail communication with the registrant may result in domain deletion!

Registry Lock

To take advantage of the additional security for your domain name, please contact your registrar, who in turn will pass your request to the registry to complete the process. Once we have set your domain a registry lock status, you (or anyone else for that matter), will be unable to make any configuration changes to that domain, except for domain renewal.

Should you want to change/update your domain name information, your domain name registrar will have to make a written request to us. Then, we will first verify the request by placing a call with registrar’s appointed person, before removing the registry lock status from your domain name. Though this procedure provides a higher level of security to your domain name, it makes it less flexible as it takes longer to complete. Furthermore it can only be requested during the registry’s office hours.

Registrar is a service provider who manages your domain names and is an intermediary between a domain holder and registry. List of official registrars is available here.

Changing the registrant

A registrant transfer process can be initiated anytime upon request of the current registrant. The transfer is made through domain registrar after receiving a confirmation from the current registrant and the new registrant. After the process completes, registry will send an automatic email notification to both parties.

Changing the registrar

If you wish to change your registrar you should first set an authinfo code to a domain name you wish to move. This can be arranged at your request through the current registrar or by yourself (e.g. through registrar’s online services). Next, you submit the authinfo code to a new registrar who in turn will complete the transfer process.

Example: Let’s say you choose a password “domain111”. Use the Authinfo calculator below to generate a password digest. Then submit the digest to the current registrar either online or by other means of communication (e.g. mail, phone). Once this code has been set for the domain name you wish to move, submit the original password (i.e. “domain111”) to the new registrar.

AuthInfo SHA-256 code **

Domain dispute is a procedure that can be initiated by the appellant that asserts that the registered domain name of a domain-name holder violates its rights.

In conjunction with legal experts, Registry has prepared a Procedure for Alternative (Domain Name) Dispute Resolution (ADR). All Domain Name Holders, Registrars and Registry are bound by it. This procedure is also a quick and inexpensive way of resolving domain name disputes but it does not exclude the possibility of using other legal remedies.

At some point, you simply need to trust

Information Security Administrator at the Registry, Zala Primožič

Already during my studies at the Faculty of Security Sciences, where we focused mainly on police work, criminology, criminology and criminal law, I also became interested in information technology. So, I started thinking about upgrading my security skills with information security and computing skills, and maybe merging those areas someday.

My constant goal is: to manufacture something, to create something

Andrej Bagon, technical engineer at Registry .si

I have been interested in computer science since I was a child. We had a printing house at home and around ’85 the first computers started to appear in our office. If I remember correctly, my father was the first in our area to have a 286 – this meant Windows 3.0, CorelDraw 2.0 and a dot matrix printer. This caught my attention and it was in this way that I came across first text programming languages ​​- Basic and Pascal.

Teamwork is key

I got into programming by accident. In fact, when I went to high school, I said I would never enroll in a college where there is a lot of math and physics. But it turned out quite differently.
