Which .tz Domain Should You Choose? .co.tz, .or.tz, .ac.tz Explained

For most Tanzanian businesses the right choice is .co.tz. Other .tz endings exist for organisations, schools and government, and some of them need supporting documents.

Overview

The .tz domain family is divided into second-level endings. Each one tells visitors what kind of organisation owns the site. Choosing the right ending builds trust and is good for local search.

Why it happens

• TZNIC, the national registry, keeps separate endings for different kinds of owners.
• Some endings are restricted to eligible owners, so they may need proof when you register.

What it means

A commercial business normally uses .co.tz. A non-profit uses .or.tz. A school or university uses .ac.tz or .sc.tz. Government bodies use .go.tz. If an ending is restricted, registration may need supporting documents, and the support team will tell you what to send.

How to fix it

1. Business, shop, startup or personal brand: choose .co.tz.
2. NGO, association or non-profit: choose .or.tz.
3. University or college: .ac.tz. Primary or secondary school: .sc.tz.
4. Government body: .go.tz. Other endings such as .ne.tz and .me.tz also exist.
5. Check the name is free with how to check if a domain is available, then order it.
