Short answers for buyers who need to confirm .SU use cases, restrictions, transfers, bulk search, payment, or reseller/API support before continuing.
.SU is a legacy country-code top-level domain originally associated with the Soviet Union. It remains present in the root zone, but buyers should treat it as a policy-sensitive ccTLD rather than a normal generic TLD.
Availability and eligibility depend on current registry and registrar support. Public sources reviewed also describe mandatory registrant identification changes for .RU, .РФ, and .SU from September 1, 2026, so customers should confirm current requirements before ordering.
Public sources reviewed state that mandatory identification for .RU, .РФ, and .SU registrants is scheduled from September 1, 2026. Customers should prepare accurate registrant information and follow the current process supported by the registrar.
Public reporting in 2025 discussed ICANN moving toward retirement of the legacy .SU domain over a future period. Because policy handling can change, customers should use .SU only after reviewing current registry and registrar support.
You can use .SU when it fits your brand and compliance needs, but for broad global trust many buyers may also compare .COM, .NET, .ORG, or active regional alternatives.
Bulk planning may be possible where supported, but because .SU has policy-sensitive handling, use bulk search as a planning step and confirm current eligibility before committing.
If supported and eligible, you will generally need to unlock the domain where applicable, obtain the authorization code or transfer credentials required by the current process, and submit the request through NiceNIC domain transfer.
Yes. NiceNIC supports automated crypto deposit/payment options for supported assets such as USDT, BTC, ETH, and LTC, while the domain itself remains subject to registry and registrar policy.
Only for resellers who can clearly explain current .SU requirements to customers. NiceNIC bulk tools and reseller API can support domain workflows where the TLD is available and policy requirements are met.
Register a new .SU, transfer an existing domain, or upgrade your account level for bulk registration and reseller API use.
