DUNS vs BRELA: Which Does Your Tanzanian Business Need?

One of the most common confusions we encounter at Ghostech Team is the assumption that DUNS and BRELA are alternatives, or that getting one means you no longer need the other. They are not the same thing, they do completely different jobs, and most Tanzanian businesses that operate seriously online need both. This article explains what each one is, what each one is for, and the decision tree for working out which you need first.

BRELA: your business's legal existence in Tanzania

The Business Registrations and Licensing Agency, known as BRELA, is the Tanzanian government body responsible for registering companies, business names, trademarks and industrial property. When you register a company with BRELA, you receive a Certificate of Incorporation; when you register a business name, you receive a Certificate of Registration. Either way, this is the document that proves your business legally exists under Tanzanian law.

BRELA registration is a legal requirement before you can:

• Apply for a TIN at the Tanzania Revenue Authority.
• Open a corporate bank account in Tanzania.
• Sign contracts in the company's name.
• Apply for a Business Licence at your municipal council.
• Hire employees and pay statutory PAYE, SDL and NSSF contributions.
• Apply for almost any government tender.

In short: BRELA is non-optional for a real business in Tanzania. Without it, you are trading as an individual and your tax, liability and contractual position are very different from what most owners assume.

DUNS: your business's identity outside Tanzania

The Data Universal Numbering System (DUNS) is a private nine-digit identifier issued by Dun & Bradstreet, a credit reporting agency headquartered in the United States. It is not issued by a government, it does not create any legal status, and inside Tanzania almost nobody will ever ask for it. Outside Tanzania, however, it has quietly become a standard way for foreign platforms and procurement systems to confirm that your company is real and to look up basic facts about it.

A DUNS number is commonly required when you want to:

• Register an Apple Developer organisation account.
• Register a Google Play Console organisation account.
• Become a vendor on Amazon Business, SAP Ariba, Coupa, SAM.gov.
• Tender for projects funded by the World Bank, USAID and some UN agencies.
• Open accounts with certain US-based payment processors and banks (Stripe Atlas, Mercury).

We covered the full DUNS application process in our article on how to get a DUNS number in Tanzania.

The decision tree

Use this simple flow to work out what your business needs in 2026:

• Trading only inside Tanzania, no apps, no foreign clients? You need BRELA. You do not need DUNS.
• Trading inside Tanzania plus selling services to foreign clients online? You need BRELA. You probably do not need DUNS unless your clients are using procurement systems that require it.
• Publishing an app on Google Play or Apple as a company? You need both. BRELA first so you can verify your company's existence, then DUNS so Google or Apple can verify it.
• Bidding on foreign government or NGO contracts? You need both, plus often additional vendor registrations (CAGE code, SAM.gov registration etc.).
• Selling on Amazon, SAP Ariba, Coupa, or similar enterprise procurement? You need both. The DUNS file must match your BRELA registration exactly.

Order matters: always BRELA before DUNS

A common and avoidable mistake is to apply for DUNS first because the international deadline feels more urgent. The problem is that Dun & Bradstreet's verification team will sometimes ask for proof of legal registration, and if you cannot produce a BRELA certificate, the application stalls or is rejected. Getting BRELA in place first means that when D&B's analyst emails you, you can answer immediately and the DUNS file goes through cleanly.

The names must match exactly

This sounds obvious and it is the single most common reason DUNS applications are rejected or take twice as long. If your BRELA certificate says Mbalizi Digital Services Company Limited, your D&B application must say the same. Not "Mbalizi Digital Services Ltd". Not "Mbalizi Digital Services Co. Ltd". Spell out the words exactly as they appear on the certificate, including any commas. The same rule applies later when you fill in your Google Play Console or Apple Developer organisation account — the name on the developer account must match the DUNS file which must match the BRELA file. Any inconsistency triggers manual review.

What each one does NOT do

It is just as important to understand what each registration is not.

• BRELA does not give you a tax number. That is the TIN, issued separately by TRA.
• BRELA does not give you a sector licence. That comes from the relevant regulator (TCRA for telecoms, BoT for financial services, TMDA for medical devices, etc.).
• DUNS does not register you with the IRS or any other US tax authority.
• DUNS is not a credit score. Your D&B file may eventually contain payment history and a rating, but a brand-new DUNS file is essentially blank.
• Neither replaces a proper Anti-Money-Laundering programme if you handle client funds. That is a regulatory requirement of its own.

How much they cost

• BRELA: a private limited company in 2026 costs around 200,000 TZS in official fees, plus stamp duty and minor disbursements. Business name registration is cheaper, around 50,000 TZS. Most owners pay an agent or lawyer an additional 200,000 to 500,000 TZS to handle the filing.
• DUNS: free if you apply directly. Paid expedited service through D&B is available but expensive. Any third party charging you for a "DUNS number" is selling their time on the application, not the number itself.

How long they take

• BRELA typically issues a certificate within 5 to 15 working days for a clean filing in 2026.
• DUNS typically issues a number within 8 to 30 working days. Faster if your business is already easily verifiable online.

A worked example

A Mbeya-based startup wants to publish a small Android app for ordering fresh produce. The path looks like this:

1. Register the company at BRELA. Receive Certificate of Incorporation. (1 to 3 weeks.)
2. Get TIN from TRA. (1 week.)
3. Get business licence from Mbeya City Council. (1 to 2 weeks.)
4. Apply for DUNS using the BRELA name and certificate. (2 to 4 weeks.)
5. Open Google Play Console organisation account using the DUNS number. (1 to 4 weeks of verification.)
6. Publish app.

End to end, this is a two to three month administrative project. Treat it as a project plan, not a series of unrelated tasks.

How we help

At Ghostech Team we walk Tanzanian businesses through this whole pipeline. We do not handle BRELA filings ourselves — that is a regulated legal service — but we partner with Tanzanian lawyers who do, and we handle the DUNS application, Google Play Console setup, Apple Developer setup, and the supporting documentation (websites, privacy policies, terms) that the international side of this chain requires. See our services page for the scope or message us for a free initial conversation.

BRELA and DUNS are not in competition. BRELA gives you legal existence in Tanzania; DUNS gives you a recognised identity abroad. Most ambitious Tanzanian businesses in 2026 will need both, and getting them in the right order, with matching details, saves weeks of frustration.
