IANA currently lists .SU as a country-code top-level domain managed by the Russian Institute for Development of Public Networks, also known as ROSNIIROS. Its continued operation is documented in the IANA .SU delegation record.
Considering this extension for your website? Start with NiceNIC's .SU domain search to check your preferred name, review current pricing, and understand the registration requirements.
Why register a .su domain name?
The strongest reason to choose .SU is that it fits your project’s identity. Consider how the complete address will look, sound, and make sense to your audience.
Give a historical or cultural project a relevant address
A Soviet history archive, research publication, or cultural collection may find that .SU reinforces its subject matter. The connection is visible in the website address before someone opens the page.
Make the project’s purpose equally clear on the website. Explain who maintains the collection, where its material comes from, and how visitors can explore or contribute. These details help turn an unusual domain into a useful destination.
Find a concise name that suits your brand
Your preferred wording may be available under .SU even when another extension is already registered. A concise address can be useful on printed materials, presentation slides, and social profiles.
Evaluate the whole name before buying. Can someone spell it after hearing it once? Will they remember the extension? Does it resemble an existing organization too closely?
Use NiceNIC's bulk domain search to compare several candidates before deciding.
Maintain an established online identity
For an existing .SU website, the domain may already appear in bookmarks, publications, customer correspondence, and inbound links.
Keeping that address operational can preserve continuity for readers and customers. Maintain access to the account, keep registrant information current, and plan verification and renewal tasks ahead of their deadlines.
Use multilingual naming where supported
The .SU registry supports internationalized domain names, including Cyrillic and other approved scripts. This can help a project use a name familiar to its audience. The registry describes these capabilities on its official .SU information page.
Before ordering an internationalized name, confirm that NiceNIC supports the exact characters you need and test how the address appears in your intended applications.
What are the current .SU registration requirements?
Identity verification is an essential part of planning a .SU registration.
The rules effective September 1, 2026 provide for identification through Russia's Unified Identification and Authentication System, commonly called ESIA. They also require annual identification to maintain the right to administer a domain. The registry publishes the current registration rules.
Applicants must provide accurate personal or organizational information. The rules include provisions for foreign legal entities, so a blanket statement that all foreign companies are prohibited would be inaccurate. However, practical registration depends on completing the required verification through a supported registration channel.
If you are applying from outside Russia, contact NiceNIC support with your country and applicant type before paying. Ask which verification process is available and what information you must provide.
The current rules allow names of 2-63 characters before .SU, subject to permitted characters and other restrictions. Names must begin and end with a letter or number; internationalized names also have a Punycode length limit. Confirm the availability and handling of any unusually short name before ordering.
How does .SU handle WHOIS privacy?
Public contact information and registrant verification are separate matters.
The registry has announced that, from October 5, 2026, WHOIS will display a registrar contact-form link instead of the domain administrator's email address and telephone number. This change allows contact without publishing those particular details. See the official WHOIS announcement.
This does not remove identification requirements or mean that every registration field becomes private. Review the current disclosure rules for your applicant type before submitting information.
Is a .SU domain good for SEO?
Google includes .SU among the country-code extensions it treats as generic for geographic targeting. That means its search treatment differs from a country-code extension that strongly signals one particular country. This distinction appears in Google's international website documentation.
Choose .SU for audience and naming relevance. The extension itself does not establish your expertise or guarantee search visibility.
For a useful website, publish clear answers to your audience’s questions, identify the people behind the project, and connect related pages with descriptive links. If you publish in several languages, provide separate URLs and appropriate language annotations so visitors and search engines can find the relevant versions.
How to register a .SU domain with NiceNIC
1. Search and compare your preferred names
Enter your chosen name on the NiceNIC .SU registration page.
Shortlist names that are easy to communicate and appropriate for your project. Check for conflicting brand names before committing to an address.
2. Confirm verification and ongoing costs
Review the registration price, renewal price, and any applicable service charges. NiceNIC's domain pricing page helps you compare the initial purchase with ongoing costs.
Confirm the supported identification process and follow the instructions for your applicant type. For an existing domain, review any verification notices as well as the renewal date.
3. Complete the order and prepare your website
Submit the required information and complete payment through the available checkout process. Check the order status and registration confirmation before announcing the domain publicly.
Once the domain is active, configure its nameservers and DNS records for your chosen hosting service. Test the website address, contact forms, and email configuration before launching.
Build more than a domain registration
Your domain gives visitors an address. The services connected to it make that address useful.
NiceNIC Business Email lets your team communicate using domain-based mailboxes. Choose recognizable mailbox names for inquiries, editorial submissions, or customer support, and assign responsibility for monitoring them.
Your website also needs HTTPS. Review what your hosting provider includes, and explore NiceNIC SSL certificates when you need a suitable certificate. Install it correctly and test the pages where visitors submit information.
For a commercial website, make the next step obvious: show the offer, explain the price, answer common questions, and provide a clear purchase or inquiry button.
Frequently asked questions
Is .SU still active?
