What is WHOIS?

The .CZ WHOIS database contains a list of all registered .CZ domain names and can give information on whether a domain is registered already, when it is going to expire, and in some cases who the registrant is.

Simply enter the full .CZ domain name into the search bar above and hit enter to see the info. If there are no results then it is likely that the domain name is still available!
