  • Maximum: 63
  • Letters and numbers
  • Hyphens ("-"), however not at the beginning or directly in front of the TLD

Domain Registration

.SU domains can be registered online through webinterface or API.

For organizations incorporated in the Russian Federation the following additional parameters are required:

X-RU-CODE = <Taxpayer identification number>
X-RU-KPP  = <Territory-linked taxpayer number>

For natural persons the following additional parameters are required:



As already announced, the .RU registry has introduced new registration rules:

Registrants of .SU domain names - specifically the owner contact (contact handle) - must verify their identity by submitting respective documents.

These changes also apply to all existing .SU registrations. Effective April 1, 2010, the non-submission of documents to the registry may result in the deletion of domains.

Which documents are required?

- For legal entities / companies:

A copy of a document confirming state registration of a legal entity issued by the state authorities
(certificate of registration, excerpt from the commercial register)
- For natural persons and entrepreneurs:

A copy of passport

Please note:

The documents have to be readable, personal details and date of issue have to be obvious. 
You can submit the documents in your national language. You do not have to translate them.

How to submit the documents?

Please send the documents as PDF file only via e-mail to the e-mail address:

The e-mail subject MUST include the respective domain name and your RRPproxy
account name following this syntax:
domain: <domain name>.su registrar: <RRPproxy account name>
Example: domain: registrar: reseller1


In order to help prevent abuse, please collect yourself the documents of your customers and send us the files in the above format by e-mail.

We will forward the registry response about the successful or unsuccessful confirmation of the owner contact to our resellers by e-mail using the e-mail address given in your RRPproxy account. If a contact handle has been successfully confirmed once, it will not have to be verified again.

Because of the new rules, we are going to change the registration process for new .SU domain effective March 22, 2010: When registering a .SU domain, the ID documents have to be submitted by e-mail in the way described above within three business days at the latest. The domain status will read "processing" until the owner contact has been confirmed by the registry.

Domain Modification


It is not possible to change the registrant of a .SU domain through our system. You have to sent the original letters by mail to the registry. Further information can be found at:

Domain Renewal

As .SU domains can only be registered on a yearly basis, they cannot be renewed explicitly. To renew an .RU domain you have to set the domain renewal mode or default renewal mode to "AUTORENEW" or "RENEWONCE".

Deletion Process

Besides the explicit deletion request through our system you have to sent an original cancelation letter by post to the registry. Further information can be found at:


The contact organization must contain a legal entity. Abreviations of names are not allowed. Full first name and last name is required. RU-Center does not allow to change an existing handle. Please always create a new handle if you want to change contact data. The nameserver list must contain at least two nameservers in different Class C networks. Please make sure that a valid and working email address is given in the contact handles used for registrations or modifications, as this is checked for by the registry. If the email address is not working you will receive an error 402.


.SU transfers can not be done through our API system and are officially not supported. However it is possible.

Transfer procedure

Please follow instructions below:

  • You have to arrange the complete transfer with Nic.Ru yourself. Therefore you will need our registrar id, which is: 1594/NIC-REG
  • If the transfer has been completed successfully please request the domain with the TransferDomain command. It will then be added to your account within a few hours automatically.
  • Please note: If the domain has not been transferred successfully within 14 days, the transfer request will be cancelled.


Generally restores are possible. A restore can be requested via API command or via webinterface.

command = restoredomain
domain  =

Please note: The restore request will be manually processed by our support team. You will be notified by email.
