.AT is the TLD for Austria, and is regulated by the registry. In addition to .AT names, OpenSRS offers domain name registrations for the following second level domains: .CO.AT and .OR.AT.

.AT is an open registry; you do not have to be an Austrian resident or business operator to register a .AT domain.

Registration details

Registration details can be found in the TLD reference chart.


.AT domains renew automatically.  A domain must be cancelled 3 days before the expiry date to avoid renewal.


To cancel a .AT registration, you need to submit the .AT Cancellation form. This form must be signed by the registrant and can be submitted by email to

If the registrant is an organization, a company stamp must be affixed to the form in the area labeled Company Chop.

Important: There is no refund when you cancel a .AT name. The cancellation must be processed at least 3 days prior to expiry, otherwise the domain will be auto-renewed by the registry.

Unresponsive Registrant

If the reseller cannot reach the registrant, or if the registrant refuses to pay, refuses to sign the form, or claims not to have heard of the reseller, a Domain Withdrawal can be processed.

To process this withdrawal, the reseller will have to contact OpenSRS support. They can state "I can not reach the registrant, please give the domain back to the registry".  Once OpenSRS support processes the withdrawal the registry will no longer point the domain at OpenSRS.  The registry will take over and contact the registrant.  If the registrant is still unresponsive, the domain is deleted by the registry.

There are no refunds for this process. 


Registrar to registrar transfers require auth codes. The auth code is set by the sponsoring registrar and is foreseen for the domain holder only who can at any time ask his registrar for the AuthInfo.  With this AuthInfo a domain holder can transfer his domain to any ISP/registrar.

For more information on transfers, see "Transferring domains and changing domain ownership"

Changes of ownership

.AT Registrant ownership changes require a form to be completed in addition to the standard request through our web interfaces. The Change of Holder form must be emailed to
