DUNS Number in the UAE: How to Get One for Your Business

A DUNS number (D-U-N-S^®, short for Data Universal Numbering System) is a unique nine-digit identifier assigned to a business by Dun & Bradstreet. It acts as a global "passport number" for your company — the reference that international banks, corporate buyers, tender platforms and software marketplaces use to confirm your business exists, and to look up its credit and payment history.

One point to get straight immediately, because it trips up most UAE founders: a DUNS number is not a UAE government registration. It is issued by Dun & Bradstreet, a private business-information company. It does not replace — and is not connected to — your trade licence number, your Tax Registration Number (TRN), or your establishment card. It sits alongside them, as an internationally recognised business identifier.

What is a DUNS number used for?

In the UAE, businesses most commonly need a DUNS number for one of these reasons:

• Building a business credit profile. The DUNS number is the key that links your company to its credit file. Suppliers, lenders and partners use that file to judge whether to extend credit or payment terms.
• Enrolling in the Apple Developer Program as an organisation. Apple requires a DUNS number to verify a company's legal identity before it will let you publish apps under a business name — this is one of the most common reasons UAE companies apply.
• Tenders and corporate supplier onboarding. Many multinationals, and some government and large-enterprise procurement platforms, ask for a DUNS number as part of vendor registration and due diligence.
• Cross-border trade and partnerships. Overseas customers and distributors often use the DUNS number to verify a UAE counterparty before signing.

If none of the above applies to you, you may simply not need one — it is not a mandatory UAE compliance step for most companies.

DUNS number vs trade licence number vs TRN — what's the difference?

These are three completely different identifiers, issued by three different bodies:

You need the trade licence to operate and the TRN to meet your tax obligations. The DUNS number is optional — you obtain it when a counterparty, platform or lender asks for it.

How to get a DUNS number in the UAE

The application is made directly to Dun & Bradstreet, not to a UAE authority. As a general guide:

1. Check whether you already have one. Established companies are sometimes already in the D&B database. Use D&B's official look-up before applying, so you don't create a duplicate record.
2. Apply through Dun & Bradstreet. Submit the request via the official dnb.com channels for your region.
3. Provide your company details. Typically the legal company name exactly as licensed, physical business address, telephone number, a named contact, your business activity, the year the business started, and the number of employees.
4. Support it with your trade licence. Your UAE trade licence is the primary document proving the legal name, address and activity you have declared. The details on the application must match the licence exactly, or verification stalls.
5. Wait for verification. D&B verifies the business before issuing the number. Standard processing is free but can take several weeks; expedited paid options are available in some markets.

Timelines, fees and the exact application route change from time to time and vary by region — always confirm the current process on the official Dun & Bradstreet site before you apply.

What it costs

Obtaining a DUNS number through the standard route is free. Dun & Bradstreet also sells expedited processing and paid credit-monitoring products; those are optional and separate from the number itself. Treat any third party that charges you a large fee purely to "issue" a DUNS number with caution — the standard application is free and you can make it yourself.

The most common reason UAE applications get delayed

Mismatched company details. D&B verifies your business against independent records, so if the legal name, address or activity on your application does not match your trade licence — a shortened trading name, an old office address, a different activity description — verification stalls or the record is rejected. Before applying, make sure your licence, tenancy/Ejari and contact records all say the same thing.

This is where a lot of companies discover their underlying paperwork is out of date. If your licence details have drifted from reality, our PRO services team can bring the trade licence, address and activity records back into line, and our licence amendment specialists handle any formal changes. If you are still at the setup stage, our business setup consultants will structure the licence correctly from the start — and accurate, up-to-date accounting and bookkeeping is what gives your business a credit profile worth having once the DUNS number is live.
