.cz Domain: The Official Country Extension of Czechia
.cz is the country-code extension of Czechia. It entered the root zone on 13 January 1993, twelve days after the country separated from Czechoslovakia. The registry is CZ.NIC, a non-profit association of legal entities based in Prague, which operates the Central Register and the primary name server for the zone. The governing text is the Rules of Domain Name Registration in ccTLD .cz, in force since 20 January 2026, and it carries the alternative dispute resolution rules as its own annex.
The eligibility question has a short answer: there is no requirement. Not one clause in the nineteen-page rulebook asks about nationality, residence or any link to Czechia; the seven conditions for registration are technical and financial, and names are allocated in the order requests arrive. A Turkish resident or company can hold the name directly. The single reference to Europe sits in article 12.6 and bites on demand, not at registration: in a dispute you may be asked to supply a valid delivery address in the EU or EEA, or to name a representative with one.
Names are registered in whole years, for up to ten years. Once the expiry date passes, the name enters a sixty-day protective period the next day; if it is not renewed within the first thirty days, CZ.NIC may withdraw the delegation, and after that no change of name servers brings the address back. If the protective period runs out, the registration lapses and the preferential right goes to auction. Start by checking whether the name you want is free on the domain name search page.

.cz Domain Lifecycle
What happens day by day after it expires
Day 0 is the domain's expiry dateIn short: for .cz the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .cz, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.
Domain Is Available (Available)
A .cz address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.
Domain Is Active (Active Period)
Once registration is complete, the domain is registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.
Domain Is Available Again
Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .cz Domains
The questions people actually ask before registering — answered plainly.
-
Yes, in your own name. Nothing in CZ.NIC's registration rules asks about nationality, residence or any link to Czechia; the conditions are that the name is free, complies with the naming rules, has a contact assigned in the holder role, and that the fee is paid. The only European condition sits in article 12.6 and applies on demand: if a dispute or official proceeding arises, you may be asked to supply a valid delivery address in the EU or EEA, or to name a representative with one. Nothing of the sort is asked at registration.
-
No. The rulebook contains no pre-registration document check; none of the seven conditions in article 4.5 involves paperwork. CZ.NIC's power to request further data is limited to two situations: where your identity must be established unambiguously in a court, arbitration, administrative or criminal proceeding, details such as date of birth or company number may be requested; and you must report any change in your registered data without delay and evidence its accuracy on request. So there is no document file, but there is later verification.
-
From one to ten years, in whole years. Article 4.3 sets the ceiling at ten years and article 5.2 applies the same ceiling to renewals, which may be repeated indefinitely. Every term in between is selectable — a two, three or seven-year registration is equally possible. The renewal instruction must reach CZ.NIC by the expiry date at the latest; after that, a retroactive extension is still possible during the protective period.
-
The day after the expiry date the name enters a sixty-day protective period. If it is not renewed within the first thirty days, CZ.NIC may withdraw the delegation; from that point changing name servers or assigning a new server set will not bring the address back, so the website and email stay down. If the protective period also runs out, the registration lapses and the preferential right to the name is auctioned in CZ.NIC's Doménový prohlížeč service. In short, you have sixty days to recover a missed .cz name.
-
There are two separate operations. A change of holder is made on an instruction submitted through the designated registrar, and the registrar may only submit it on the written request of both the current and the future holder; the new holder is bound by the version of the rules in force on the transfer date, and the transfer does not change the expiry date. Changing registrar is independent and does not affect the name itself. You can start the process from the domain transfer page.
-
No. Article 4.6 lists the permitted characters as the letters a-z, the digits 0-9 and the hyphen only; a name may not begin or end with a hyphen, nor contain two consecutive hyphens. Czech letters such as č, ř or š therefore cannot be registered under .cz, and the zone offers no internationalised domain names. The upper limit is 63 characters; the rules set no lower limit, which is why very short names exist in the zone.
