Service & Support



It is internationally usual for registries to make domain data (so-called Whois-data) available to the public. One reason is to get information about the person who is responsible for the content and offerings of a website, as not all websites contain the imprint prescribed by the law. On the other hand, it is possible to contact the domain holder directly in case of a legal infringement (e.g. regarding content, spam, domain grabbing etc.).

Publication regulated in the General Terms and Conditions

With the registration of a domain the holder expressly accepts the publication of his data (see point 1.5. of the General Terms and Conditions). This also applies if the domain was registered by a different person on behalf of the customer.

Appointment of a trustee in order to prevent publication

The display of the phone or fax number as well as the e-mail address can be hidden in the public database – this requires a modification of the person data. If the entire data should be hidden, the domain holder needs to appoint a trustee (e.g. notary, lawyer, ISP) by transferring the domain to him. We recommend to define the trustee’s rights regarding the domain by concluding a (written) contract, as the trustee is specified as the official domain holder who is fully authorised to dispose of the domain.

Whois-queries are subject to copyright

The Whois-database is a copyrighted database. Single domain queries are have been made available to the internet community and are free of charge until further notice. has the sole right to duplicate, disperse, submit or publish the database or parts of it.

Where can I find the current Whois-data?

You can view your domain data by using the domain query on the homepage. This is the most up-to-date and reliable source for .at-domains. Due to data protection, no information about the invoice recipient and the domain's key date are available.

What is an AuthInfo and what do I need it for?

For every domain there is an AuthInfo - a unique number/character combination which serves as confirmation code for the change of provider. It 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. The new ISP/registrar shall then set a new AuthInfo for the domain, otherwise the used one remains valid.

How do I make a data modification?

The relevant data must be sent to electronically - via online application (usually by the ISP). In addition, most data modifications require a written confirmation from the domain holder. As soon as both are available, the modification will be processed. If your ISP is also a registrar, please contact him in order to change data.

If you want to modify a NICAT-handle, please complete the corresponding online form. Please note that this modification of a handle is only possible if the handle is neither administrated by a registrar nor used as a handle of a domain holder.

My domain is administered directly at - how do I get my AuthInfo?

In this case you can request a token code External Link on the website which will be sent to the e-mail address in the domain holder's data. This code is valid for 21 days and is bound to a specific ISP/registrar. Once you have received the token code and transmitted it to your new ISP/provider, he can take the domain automatically into his administration. Alternatively, also the new ISP/registrar can request a token code, but it will always be sent to the domain holder.

What is a change of the holder and how can it be performed?

A change of the domain holder is the transfer of a domain to another natural or legal person. In case of an organisation, modifications of the legal form or company name are also regarded as a change of the holder. Both the old and the new domain holder must confirm this transfer in writing. The required document can be found here. In addition, the data must be submitted to via online application (usually by the ISP).

If together with the change of domain holder the domain shall be transferred to a new registrar, the new registrar is the competent authority: With the AuthInfo he can take over the domain (see above: change of registrar) and change the holder's data. The previous domain holder has to hand over the AuthInfo to the new domain holder so that he can forward it to the new registrar.
