.AT is the TLD for Austria, and is regulated by the nic.at 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 Domain NIS2 Compliance
nic.at is updating .AT domain registration rules to comply with Austria's national implementation of the EU NIS2. These changes affect registrant data requirements, WHOIS publication, and identity verification, and apply to both new and existing .AT domains.
| ⚠ Important Domains that fail to meet these requirements may be suspended (serverHold) or permanently deleted. |

Key Dates at a Glance
| Date | What Changes |
|---|---|
| 1 October 2026 | The new registrant-data requirements, WHOIS publication changes, and the risk-based verification process take effect for all .AT domains. |
What Registrant Data Is Now Required
For all new registrations, ownership changes, and contact updates, the following information must be accurate and complete:
- Full name (of the registrant)
- Organisation name (only where the registrant is a legal entity)
- Valid email address
- Valid, working phone number-no placeholder or dummy numbers
- Full postal address
What Is Published in WHOIS
Organisations (Type: "organisation")
- Name, address, email address, and phone number are published for all .AT domains held by a legal entity.
Private individuals (Type: "privateperson")
- Personal contact details are not published in the public WHOIS database.
Contact Data Changes
Fax number field removed
- The optional fax-number field is being removed completely. Transactions that still include a fax number will be rejected with an error.
Hide/disclose function removed
- The option to hide phone, email, or fax details is being discontinued. For registrants designated "organisation," all contact data will be visible in WHOIS.
- nic.at recommends avoiding personal addresses for legal entities-e.g., use info@yourcompany.com rather than firstname.lastname@yourcompany.com.
Registrant Verification Process
New registrations, transfers, owner changes, and contact updates on .AT domains are risk-assessed at the point of order. If a domain's data is classified as suspicious or high-risk, a verification process is triggered:
- OpenSRS contacts registrant directly to verify their name, postal address, and email address. The registrant receives a secure verification link, valid for 51 days.
- Nic.at (registry) will also contact the registrant directly, but only as part of its standard procedures – specifically on day 14 if verification is still outstanding, when domain name is set to serverHold, and when domain is locked (SNV locked applied for non-verification).
- Resellers are not cc’ed on any of these direct verification notifications, whether from us or from nic.at
- Phone numbers do not need to be explicitly verified through this process, but remain mandatory and must be correct and functional-an obviously false or non-functional number can still trigger verification.
Resellers will be notified-separately from the registrant's verification request when:
- a domain is flagged and up for verification,
- a domain has been suspended (serverHold) because verification wasn't completed in time, and
- an SNV (non-verification) lock has been applied.
Verification Timeline
| Timeline | What Happens |
|---|---|
| Day 0 | Verification process begins; the reseller is notified. |
| Day 14 | If still unresolved, nic.at contacts the registrant directly as a reminder. |
| Day 21 (+3 days) | The verification window closes. |
| Next 30 days | serverHold is applied; the domain is removed from the DNS. |
| Day 51 (+3 days) | SNV (non-verification) status is applied |
| Day 51–110 | A roughly 59-day lock / cooling-off period applies. |
| Day 110 | The domain is permanently deleted if verification is still incomplete. |
Effect on Other Domains Linked to the Same Registrant
- If a domain fails verification and is placed on serverHold, other domains associated with the same registrant handle will also be selected for verification.
- Those other domains are not placed on serverHold immediately-each proceeds through its own complete verification process first.
Withdraw During Verification
- The "Withdraw" is blocked for a domain from Day 0 of the verification process until the domain is either successfully verified or deleted. This covers the pending, serverHold, and SNV stages.
Retention of documentation
- As per registry policy, we will retain the registrant documentation used for verification for 1 year. All documents will be deleted after 1 year.
Acceptable verification documents
Depending on the registrant type, nic.at may request supporting documentation:
Natural persons
- Passport or national ID
- Utility bill
- Bank statement
- Payment verification
- Video or on-site identity verification
Legal entities
- Commercial register extract
- Founding documents
- Federal Gazette entry
- VIES request
- Comparable official documentation.
