How to Register a .si Domain

Buying a .si domain is a straightforward process. Because there are no geographic restrictions, the registration process is just like buying a .com or .net domain. Here is everything you need to know about purchasing your .si domain.

Step 1: Check Availability

The first step is making sure your desired name is available. You can use our lightning-fast .si availability checker to instantly query the official Register.si RDAP database. Our tool will tell you immediately if the domain is free to register, already taken, and even suggest AI-optimized alternatives.

Step 2: Choose a Registrar

The .si registry (ARNES) does not sell domains directly to the public. Instead, you must purchase through an accredited registrar. While some major registrars don't carry .si extensions, many global platforms do. Popular options for buying .si domains include:

  • Hostinger: Known for competitive pricing and easy setup.
  • INWX: A favorite among domain investors with a massive selection of ccTLDs.
  • Gandi: Offers excellent privacy and DNS management tools.
  • EuroDNS: Specialists in European country-code extensions.

Step 3: Registration Requirements and Costs

Registering a .si domain usually costs between $15 and $30 USD per year, depending on the registrar. Keep in mind:

  • Length: Domains must be between 2 and 63 characters long.
  • Characters: Only letters (a-z), numbers (0-9), and hyphens are allowed. Hyphens cannot be at the beginning or end of the domain.
  • IDNs: .si supports Internationalized Domain Names (including specific Slovenian characters), but for global tech brands, sticking to standard ASCII is recommended.

Secure your brand before someone else does. Check your .si domain availability right now.
