How to Register a .co.tz Domain Name

If you want to register a .co.tz domain, you've picked the extension most Tanzanian businesses trust. .co.tz is Tanzania's commercial namespace — the local equivalent of .com for companies operating in the country. Registering one tells your customers, and search engines, that your business is genuinely Tanzanian. This guide explains who .co.tz is for, what it costs, how to register one, and how it compares with the alternatives.

What is a .co.tz domain?

.tz is Tanzania's country-code top-level domain (ccTLD), and .co.tz is the commercial second level beneath it — reserved by convention for businesses and organisations. When someone sees a .co.tz address, they immediately understand they're dealing with a Tanzanian entity. That single signal does a lot of quiet work: it builds confidence before a customer has read a word of your site.

Why choose .co.tz?

• Local trust — customers instantly recognise it as a Tanzanian business
• Local SEO — a .tz/.co.tz domain is a relevance signal for Tanzania-focused searches
• Availability — your preferred name is far more likely to be free than on .com
• Professional email — pair it with addresses like info@yourbrand.co.tz
• Brand protection — secures your name in the namespace your local competitors use

How much does a .co.tz domain cost?

Pricing is shown in Tanzanian Shillings on the .co.tz page and again at checkout, with no hidden card or conversion fees. A domain is priced per year and renews each term to keep it active. You can register for multiple years at once to lock in the name and avoid the risk of a missed renewal.

How to register a .co.tz domain

The process takes only a few minutes. Search your business name, choose the .co.tz result, add it to your cart, and pay with mobile money in TZS — M-Pesa, Tigo Pesa or Airtel Money. The domain is registered automatically the moment your payment succeeds, and then appears in your dashboard where you can manage DNS, email and renewals.

What you can do with your .co.tz domain

A domain is more than a website address. Once your .co.tz is registered you can put up a full website, run professional email on your own name, or simply park the domain and forward visitors to your social pages while you build something bigger. Many Tanzanian businesses start by securing the name and pointing it at a simple one-page site or a WhatsApp link, then expand later. The important thing is that the name is yours — nobody else can take biasharayako.co.tz once you've registered it.

Professional email is one of the most valuable things you unlock. An address like sales@yourbrand.co.tz looks far more credible to customers than a free webmail address, and it reinforces your brand every time you send a message. You set it up by adding the MX records your email provider gives you, all from the same dashboard.

.co.tz vs .tz vs .com

.co.tz is the established commercial namespace; .tz is the shorter, more modern second-level option opened to the public in 2022; and .com is the global default. All three are valid choices — the right one depends on whether your audience is mainly local, whether you want the shortest possible name, and whether you also need international recognition. We break the decision down in detail in our dedicated comparison.

After you register

Once the domain is yours, point it at a website or email by editing its DNS records from your dashboard. If you're new to that, our beginner's guide to DNS explains the common record types in plain language so you can connect your name with confidence.
