How to Register a .si Domain Name

Who can register a .si domain?

The best news about the .si domain extension is that it is completely open and unrestricted. Anyone from any country can register a .si domain. You do not need to be a Slovenian citizen, nor do you need a local corporate entity or address.

Step 1: Check Availability

Before you can register, you need to make sure the name is available. Use our fast homepage search tool to instantly verify if your desired .si domain is open for registration.

Step 2: Choose an Accredited Registrar

You cannot buy domains directly from the ARNES registry. Instead, you must use an accredited registrar. You can choose a local Slovenian registrar (like Domenca or Neo-Serv) or a massive international registrar (like Namecheap or Gandi).

Step 3: Complete the Registration

Add the domain to your cart and complete the checkout process. You will need to provide standard contact information (Name, Address, Email, Phone Number). Make sure your email is accurate, as you will need to verify it.
