The rules are not the same for every extension — .tz on its own is far stricter than .co.tz.

Four rules that decide it

Length depends on the extension

A .tz registered on its own is refused below four characters — ab, a1, 123 and 9xy alike, letters and numbers. .co.tz, .or.tz, .me.tz and .ne.tz have no such rule: one character is fine.

Government names are taken

Around 900 names belonging to ministries, district councils, water authorities, regional hospitals, agencies, towns and public officials are held by the registry.

Internet body names too

Names such as icann, iana and afrinic, and strings that are themselves extensions — com, net, org — are reserved by the registry.

Some extensions have eligibility rules

Anyone can take .co.tz, .or.tz, .me.tz and .ne.tz. The academic, school and hotel extensions still register instantly, but the registry can take one back from a holder who does not qualify.

Which .tz extension can you use?

Four are open to anyone. The rest are limited to a particular kind of organisation.

Questions about .tz names

The domain search asks the registry whether a name is taken, not whether it is allowed — so a name that breaks the four-character rule for a direct .tz, or one that sits on the reserved list, comes back as available. The order completes and the payment is taken, but the registry refuses the registration and the domain is never created. Nothing is lost: we contact you, you choose a different name, and we register the replacement by hand. It costs a day rather than money, which is exactly what the checker on this page is for.

Type the name into the box at the top of this page and we check it live against the registry. If it is free you can register it straight away and pay by mobile money. If you want to know whether a name is reserved before you search, the checker further down tells you instantly.

Yes. .co.tz accepts names from one character upwards, and so do .or.tz, .me.tz and .ne.tz. The four-character minimum people run into is a rule for .tz at the second level — a name registered directly as example.tz. If your brand is a three-letter acronym, take it as .co.tz and it is not a problem.

They are the registry’s to make, not ours, and they do happen — short names have been allowed through where the registry judged there was a reason. What we cannot do is predict one, so we do not let a name that breaks the published rules go through checkout: the ordinary outcome is a refused registration after you have already paid. If you believe your case is exceptional, talk to us before you order and we will put it to the registry first. It costs you nothing to ask.

For a .tz registered on its own the registry forbids names of one, two or three characters, and the rule is about length rather than a list — the published document says the ban is “not limited to the list below”. It applies to letters, numbers and any mix: ab, a1, 12, 123 and 9xy are all refused. Four characters is the minimum there. On .co.tz the same name is fine.

No. Where the length rule applies — on a direct .tz — it counts characters, not what kind they are. A name made entirely of digits is fine once it reaches four characters, and so is a mix. Below four nothing is accepted there, digits included: the registry lists every single digit and every two-digit pair among the forbidden names. On .co.tz the length rule does not apply at all.

Our current .tz prices, including registration, renewal and transfer, are on the domain pricing page. A .co.tz is also included free for the first year with any annual hosting plan.

For the open extensions — .co.tz, .or.tz, .me.tz and .ne.tz — it is immediate once payment confirms. The restricted ones take as long as it takes us to verify your paperwork, usually the same day.

The published list says these names are reserved “in .TZ at the second-level domain name registration”, which is a direct name.tz registration. Whether a given name is also blocked at .co.tz is decided by the registry at the moment you apply, so the only definitive answer is a live availability check. Search the name and you will know in seconds.

Place names and council names appear throughout the reserved list, so the plain name is very likely blocked. What usually works is adding a word: your trade, your area, or the kind of business. Search a couple of variations and take the one that is free.

TCRA, as the authority behind the .tz registry. The list is published and updated by them, and no registrar — us included — can register a name that is on it.

Standard contact details, including an address in Tanzania. For a business name we may ask for your registration certificate. Most registrations complete the same day.

Not at checkout. Those extensions register immediately like any other name — nobody asks you for an accreditation letter, a school registration or a hotel licence before the domain goes live. The eligibility rule is still real, though: the registry checks afterwards and can suspend, block or delete a domain held by an organisation that does not qualify. If you are not an accredited college, a registered school or a licensed hotel, take .co.tz or .or.tz instead.

Yes. The registry can suspend, block or delete a name that turns out to be held by someone not entitled to that extension, and it can do the same to any .tz domain used for illegal activity. Registration is instant, but it is not a guarantee that you get to keep it if either applies.

Not through us. Once a name is registered it belongs to whoever holds it until they let it lapse. You can watch for the expiry, or approach the holder directly, but there is no way to force a transfer short of a dispute at the registry.

No. It is our plain-language guide to a document TCRA publishes. Where anything here differs from their PDF, their PDF is correct — and availability at the moment you order is what actually decides it.
