Choosing a .co.tz domain, and not losing it later
Which .tz extension applies to your organisation, why the registrant name matters more than the price, and the renewal mistake that costs businesses their address.
By Fabonic Admin
A .co.tz address tells a Tanzanian customer that you are a Tanzanian business. It is a small signal, and it does a surprising amount of work — particularly for buyers deciding whether an unfamiliar company is real.
Who can register one
The .tz namespace is run by TzNIC, and each extension has its own rules. In practice most businesses want one of these:
- .co.tz — commercial entities. The common choice for companies.
- .or.tz — non-profit organisations, associations and NGOs.
- .ac.tz — accredited educational institutions.
- .go.tz — government bodies only.
Registering through an accredited registrar means your application goes to the registry directly. Going through a reseller adds a company between you and your own domain, which matters on the day you need something changed quickly.
Register it in your own name
This is the mistake we are asked to fix most often. A developer or agency registers the domain under their own details, the relationship ends, and the business discovers it does not legally control its own address.
Whoever registers it, make sure the registrant on the WHOIS record is your company, with an email address your company controls — not a personal Gmail belonging to someone who may leave.
Do not lose it to a missed renewal
Domains expire. When one does, it goes through a grace period, then a redemption period that costs considerably more to recover from, and then it becomes available to anyone. We have watched businesses lose an address they had used for a decade because a renewal notice went to an inbox nobody reads.
Two things prevent this: keep the contact email current, and set the domain to renew for several years at a time rather than annually.
What to do next
Check whether the name you want is available, and if it is, take it before you finish deciding. Domains cost far less than the time spent choosing a second-choice name later.
