The .at domain is the country-code top-level domain (TLD) for Austria. "AT" is derived from the English name "Austria". The .at domain has existed since 1988, and since 1998 it has been managed by nic.at GmbH. The Salzburg-based company works closely with the University of Vienna, where much of the required infrastructure is located. Austria's own country domain is very popular – more than 1.2 million .at domains are currently registered.

Besides the classic .at domain, Austria offers further options for domain registration. These include .or.at for organisations and .co.at for companies and businesses. These second-level domains are also particularly well suited for search engine optimisation (SEO).

Registration takes only minutes, so an .at domain can be used right away. Changes such as a change of owner, deleting a domain or switching providers also require little time or effort.

At a glance: key facts about the .at domain

• .at domains have been available since 1988; since 1998 they have been managed by nic.at GmbH in Salzburg, which cooperates closely with the University of Vienna
• An .at domain must have at least one character, so domains such as f.at are now possible, as are domains like 1a.at – the upper limit is 63 characters
• With .or.at and .co.at there are also two Austrian second-level domains intended mainly for organisations and companies; ac.at, gv.at and other extensions are now available as well
• There are no registration restrictions for .at domains, so they can also be registered by users outside Austria; only individual second-level domains may be restricted (for example to government institutions)
