nic.at Requirements
To support its NIS2 compliance requirements, nic.at is introducing several changes affecting .AT contact data, domain transactions and verification procedures. The following changes will take effect on 1 October 2026.
Mandatory Telephone Numbers
A telephone number will be required for .AT contacts. CentralNic Reseller already requires telephone numbers in the correct format, so no technical change or customer action is expected.
Fax Numbers
Fax numbers will no longer be sent to nic.at. You can continue to store fax numbers in your CentralNic Reseller contacts. When a contact is used for a .AT transaction, our system will automatically exclude the fax number to prevent the registry from rejecting the transaction.
nic.at is discontinuing the option to hide phone numbers and email addresses. For legal entities (contacts with the person type ISORGANISATION) these details will be displayed in WHOIS. CentralNic Reseller will therefore stop supporting the X-UNDISCLOSE parameter for .AT contacts. Organizations could use generic email addresses, such as [email protected] instead of personal addresses.
nic.at will use a risk-based approach to identify contact data that may be inaccurate. This does not mean that every .AT contact will need to be verified. Instead, a technical process will identify individual cases and send them to the responsible registrar for review.
CentralNic Reseller will forward the relevant X-VERIFICATION* extensions to nic.at.
Registrars must specify how the contact was verified and retain the supporting documents for one year. If verification is unsuccessful or is not completed by the deadline, nic.at may apply serverHold, prevent further registrations using unverified data, or delete the affected domain.
