What is a .cz domain?
The .cz domain is the official country code for the Czech Republic (Czechia), managed by CZ.NIC. Prague is a major European business hub, and .cz is well-established among Czech consumers and businesses. Registration is open to anyone worldwide with no local requirements. For UK companies exporting to the Czech Republic or running operations in Central Europe, .cz signals local commitment that a generic .com cannot.
Who should register .cz?
Czech businesses, Prague-based companies, UK firms trading with the Czech Republic, and Central European organisations.

The .cz rules, and the 60-day protection period
Some registries publish nineteen pages of conditions and hide a residency test on page seven. CZ.NIC publishes nineteen pages and does not include one. The rules for .cz, in force from 20 January 2026, register a name when five things are true: the request has no defect that blocks processing, an existing contact is assigned as holder, the required fields are filled in, the applicant has agreed to the current rules, and the fee has been paid. Nothing there asks where you live.
The extension has been in the root zone since 13 January 1993, less than a fortnight after Czechoslovakia split into two countries, which tells you how quickly the new state took its own place on the internet. CZ.NIC, an association of legal entities registered in Prague, has managed it since. Names run in whole years to a maximum of ten, use the ASCII character set only, and can be up to 63 characters.
The part worth planning around is what happens if you forget to renew, because it is staged. The day after expiry the name enters a 60-day protection period. If it is not renewed in the first 30 days, CZ.NIC may pull the delegation, which takes the name out of the zone and stops the website and the email even though you can still recover it. The registration ends only when the full 60 days run out, so the site goes dark a month before the name is actually lost, and changing nameservers does not bring it back.
One duty that stays with you: registrants must report changes to their details without undue delay and, on request, prove those details are correct. CZ.NIC can also ask for extra identifying data such as a date of birth or a company identification number where it needs it to identify you.
Is .cz the right choice for you?
We would rather sell you the right extension once than the wrong one twice.
.cz works well if
- You sell to Czech customers, who look for a .cz the way British buyers look for a .co.uk and treat a foreign address as a question about delivery and support.
- You have an office, agent or supplier in Prague or Brno and want a local address without a Czech company to register it through.
- You are producing Czech-language content and want the country signal that Google says a ccTLD gives, pointed at the right country.
- You want a Central European country extension with short rules, no eligibility test and no documents to file.
Look elsewhere if
- You are covering Central Europe as a region. A .cz points at one country, and Polish, Slovak and Austrian buyers will read it as somebody else's national supplier.
- Your site is English only. The address promises a Czech supplier and the page does not deliver one, which costs more trust than the domain buys.
- You rely on auto-renewal and rarely check your email. The delegation can be pulled 30 days into the protection period, so the site goes dark long before the name is gone.
Not selling into Czechia specifically? A .com carries no country ties and will not narrow you to one Central European market. See .com pricing.
.cz vs .com: which should you register?
The trade here is reach against recognition, and it is the same trade every national extension asks you to make.
.com costs less, works everywhere, and carries no assumptions about where you are. .cz costs more and narrows you deliberately: Google says a country-code extension is a strong signal that a site is intended for a particular country, and Czech buyers read a local address as a supplier who will actually answer the phone in their timezone.
For most UK businesses the .com or .co.uk stays the primary address and the .cz goes over a Czech-language page. What does not work is buying the .cz and redirecting it to an English homepage, which gets you the annual cost of a country domain and none of the recognition it exists to provide.

.cz domain questions, answered
What people ask us before registering a .cz domain.
Can't find what you're looking for?
Ask us directlyNo. The CZ.NIC rules of registration set no residency, local address or local contact requirement. A registration goes through when the request is complete, a holder contact is assigned, the required fields are filled, the applicant has accepted the current rules and the fee is paid. A UK company or a UK individual can register one on the same terms as a Czech applicant, and no documents are filed to prove anything.
You have 60 days, but the site stops working after 30 of them. The day after expiry the name enters a protection period lasting 60 days, and the registration can be renewed at any point in it, backdated to the expiry date. If it is not renewed in the first 30 days, CZ.NIC may cancel the delegation, which removes the name from the zone so the website and email stop. Changing nameservers at that point does not restore it.
Not at present. The registration rules limit a .cz name to the characters a to z, the digits 0 to 9 and the hyphen, up to 63 characters, with no leading or trailing hyphen and no two hyphens in a row. Czech diacritics are not part of that set, so a name is registered in its unaccented form. Plan the name on that basis rather than assuming the accents will survive registration.
It gives you the right signal, not the result on its own. Google states that a country-code extension is a strong signal to users and search engines that a site is explicitly intended for a certain country, and .cz is a plain ccTLD rather than one of the codes Google treats as generic. That helps only if the page behind it is written for Czech readers. A local address over English-only content wastes the signal it just bought.
