Top .si domain registrars: detailed list
Not many domain registrars offer .si domains yet. Below, I take a closer look at the available options, including their pricing, additional features, and how easy it is to register a .si domain with each provider.
1. Hostinger – best .si domain registrar in 2026
| .si domain price: | $11.99 |
| .si renewal price: | $16.99 |
| WHOIS privacy: | ✅ Included |
Hostinger is the top .si domain registrar because it offers the most affordable .si domain registration at $11.99 for the first year. You can even register a domain for up to 3 years at an even lower annual price.
What’s nice is that WHOIS domain protection is included at no extra cost. If you don’t have a website yet, you can pair your domain with Hostinger’s hosting and website builder, too.
I found Hostinger’s domain management clear and easy to navigate. It was easy to find everything I needed, including subdomains, DNS records, and nameserver settings. You can transfer your domain or access the domain lock settings in just a few clicks, too.
2. Dynadot – best .si domain registrar for bulk domains
| .si domain price: | $12.12 |
| .si renewal price: | $13.59 |
| WHOIS privacy: | ✅ Included |
Dynadot is a reputable domain registrar that offers .si domains, along with over 800 other TDLs. It offers .si domains starting at $12.12 for the first year. The renewal price is also pretty reasonable at $13.59.
You can also bulk-buy domains on Dynadot or participate in domain auctions. It offers security features like WHOIS protection, which helps keep your identity safe when buying or selling domains and reduces spam and phishing emails.
The dashboard is easy to use, too. I like that you can set up 2FA for extra security. If you own a lot of domains, you can also organize them, bulk-edit them, and quickly see which ones need to be renewed.
3. Netim – best .si domain registrar for resellers
| .si domain price: | $21.50 |
| .si renewal price: | $21.50 |
| WHOIS privacy: | ✅ Included (partial) |
Netim offers .si domains starting at $21.50/year, which is almost twice as expensive as my other options. That said, the price stays the same upon renewal. I still wanted to include Netim specifically for resellers.
Netim has a convenient control panel where you can manage all your domains, hosting services, and email addresses in one place. Yes, Netim also offers hosting and email. You can also connect reseller tools, including Netim’s API, modules for WHMCS and Blesta, and Netim Direct.
With over 1,300 TLDs available, Netim lets you register not only a .si domain but virtually any other domain extension too.
How to get a .si domain: step-by-step guide
Registering a .si domain is simple. The main challenge is finding a registrar that offers .si domains, as the extension isn’t as widely available as more popular TLDs. All registrars on my list offer .si domains. Here’s what the registration process usually looks like:
- Choose a domain registrar. I recommend Hostinger because it offers some of the cheapest .si domain registrations and makes domain management simple.
- Enter your domain name. Search the domain name you want and check if the .si version is available. If it isn’t taken, you can purchase it right away. You can also register the .com and other relevant extensions to protect your brand.
- Add the domain to your cart. Select the domain and review the registration period, renewal price, and any add-ons before continuing.
- Fill out your information. Provide your account details or create a new account if you don’t already have one. You may also need to provide the contact information required for the domain registration.
- Complete the payment. Pay the registration fee using one of the payment methods supported by your registrar.
- Verify your registration. Follow any verification instructions sent to you by the registrar or registry. Your domain may not become fully active until any required verification is completed.
- Connect your domain to your website. Once your domain is active, use your registrar’s DNS settings to point it to your website or connect it to your hosting account.
