Berechtigung & Einschränkungen

Registrant full name mandatory (minimum characters). Single-letter first names are not accepted by the registry.

Transferverfahren

Auth code (token) sent to registrant email by NIC.AT. Valid 21 days. Transfer completes after auth code confirmed. After transfer: domain owner receives email confirmation from registry.

Inhaberwechsel

Change of Holder requires form submission. Electronic consent now accepted (checkbox/digital mechanism) as of 2024/2025. Wet-signed form no longer mandatory. If electronic consent method used: registrar must retain logs for 2 business days. For immediate deletions outside renewal cycle: AT Cancellation Form still required signed by registrant.

Domain Withdrawal available if registrar cannot reach registrant. This gives the domain back to registry; NIC.AT contacts registrant directly.

Verlängerung & Löschung

Domains auto-renew. Deletion requires written or electronic registrant consent (verifiable). If registrant refuses or is unresponsive: Domain Withdrawal to registry.

Wiederherstellung / RGP

Restore supported in real-time via RCP/API only for explicit deletions. Quarantine period applies (duration varies). Domain Withdrawal (Withdrawing) gives domain back to registry; registrar no longer manages it.

WHOIS / Datenschutz

WHOIS privacy (disclosure) controlled per contact field. By default privacy protection disabled. Fields can be disclosed/hidden: X-AT-DISCLOSE, X-AT-DISCLOSE-VOICE, X-AT-DISCLOSE-FAX, X-AT-DISCLOSE-EMAIL.

Registry can initiate registrant verification; failure results in revocation (no restore/refund) and is not communicated to the registrar.

NIS2-Konformität

No .AT-specific NIS2 implementation documented. Standard EU NIS2 obligations apply to registrars operating in Austria.
