How to Register a .co.tz Domain in Tanzania: A 2026 Step-by-Step Guide

Everything a Tanzanian business needs to know to register a .co.tz domain — the requirements, real costs, the step-by-step process, and the mistakes that get applications rejected.

Your domain name is the foundation of your online identity. For a business operating in Tanzania, a local .co.tz domain signals that you are an established, locally rooted company — which builds trust with Tanzanian customers in a way that a generic .com sometimes cannot. This guide walks you through exactly how domain registration works in Tanzania in 2026, what it costs, and how to avoid the delays that catch most first-time applicants.

Understanding the .tz domain namespace

Tanzania's country-code top-level domain is .tz, administered by the Tanzania Network Information Centre (tzNIC). Rather than registering directly under .tz, most organisations register under a second-level domain that describes the type of entity they are. The most common ones are:

• .co.tz — for companies and commercial businesses (the most popular choice)
• .or.tz — for non-profit organisations and NGOs
• .ac.tz — for academic and higher-education institutions
• .sc.tz — for schools
• .go.tz — for government bodies
• .ne.tz — for network infrastructure providers

For the vast majority of businesses, .co.tz is the right choice. It is instantly recognisable to Tanzanian customers and is rarely already taken for your exact business name.

What you need before you register

Domain registration is fast when you have your details ready in advance. Before you begin, prepare the following:

1. 1Your preferred domain name (and two or three backups in case your first choice is taken).
2. 2A valid business contact — full name, email address, and a Tanzanian phone number.
3. 3Your physical business address.
4. 4For some second-level domains such as .ac.tz or .go.tz, supporting documents proving you qualify (for example a registration certificate). Standard .co.tz registration usually does not require document verification.

Step-by-step: registering your domain

1. Check that your domain is available

Start by searching for your preferred name through an accredited registrar. If the exact name is taken, resist the temptation to add hyphens or numbers — these look unprofessional and are easy for customers to mistype. Instead, try a slightly different but still natural variation of your business name.

2. Choose an accredited registrar

You register .tz domains through a tzNIC-accredited registrar rather than from tzNIC directly. A good local registrar handles the technical paperwork, gives you a dashboard to manage your domain, and offers support in case anything needs renewing or transferring later. Choosing a registrar that also offers hosting and email keeps everything in one place.

3. Provide your registrant details

Enter your business contact information carefully. The registrant name and email address you provide become the official owner record for the domain — getting these right matters, because they determine who controls the domain in future.

4. Pay and confirm

Once you pay the registration fee, the domain is typically active within minutes to a few hours. You will receive confirmation and access to a control panel where you can point the domain to your website and email.

How much does a .co.tz domain cost in 2026?

Pricing varies between registrars, but .co.tz domains are affordable and billed annually. The headline registration fee is only part of the picture — when budgeting, also consider renewal fees (which you pay every year to keep the domain), and whether hosting and business email are bundled in. At Saby Infotech, a domain comes free for the first year with our website packages, after which domain and hosting renew together from around TZS 100,000–150,000 per year depending on your package — so there are no surprises at renewal.

We register and manage .co.tz and .com domains for businesses across Tanzania through our domain portal, and set them up to work with your website and email from day one. The most common problem we fix for new clients is a domain that a previous developer registered under their own account — which is exactly why we always register yours in your own business name, so you keep full ownership.

Common mistakes that cause delays

• Using a personal email you no longer check as the registrant contact — you may miss renewal notices and lose the domain.
• Letting a third party register the domain under their own name, leaving you without ownership.
• Choosing an overly long or hyphenated name that customers struggle to remember or type.
• Forgetting to renew — set a calendar reminder a month before your domain expires, or enable auto-renewal.

After registration: what comes next

A domain on its own does nothing until you connect it to a website and email service. The usual next steps are to set up hosting so your website has somewhere to live, configure professional business email on your new domain, and point everything together using DNS records. If that sounds technical, it is the kind of thing a good provider handles for you as part of getting your site live.

Final thoughts

Registering a .co.tz domain is one of the simplest and most worthwhile steps a Tanzanian business can take toward a credible online presence. Pick a clear name, register it in your own name, keep your contact details current, and never let it lapse. With the domain secured, you have the foundation for a website, professional email, and everything else that helps customers find and trust you online.
