A DUNS number gives a business a recognised identity that procurement teams can verify. It is commonly requested when a Nigerian company registers with an international operator, opens a supplier profile or responds to a tender that uses Dun and Bradstreet business data.
The application itself is simpler than many oil and gas vendor registrations. The difficult part is usually keeping the legal name, address and company details consistent across every record. This guide separates the information needed for DUNS registration from the larger document pack an operator may request later.

Key takeaways
- A DUNS number is a unique nine digit business identifier issued by Dun and Bradstreet.
- Search for an existing record before creating a new request because duplicate applications cause avoidable delays.
- The standard request is free, although paid expedited options may be available in some markets.
- Dun and Bradstreet normally asks for core legal and operating information, not an entire oil and gas tender file.
- The number does not expire, but the business record should be updated when the company name, address or ownership details change.
What a DUNS number is
DUNS stands for Data Universal Numbering System. Dun and Bradstreet assigns the nine digit number to a specific business location. Procurement systems use it to match a supplier to a business record and reduce confusion between companies with similar names.
A DUNS number is not a certificate of technical competence, tax compliance or oil and gas experience. It identifies the business. An operator may then use that identity as one part of its financial, compliance and vendor checks.
Why Nigerian oil and gas companies request it
Nigerian regulators do not make a DUNS number a universal licence for operating in the petroleum industry. The requirement usually comes from the operator, international customer, funding organisation or digital procurement platform that is onboarding the supplier.
- Creating a vendor profile with an operator or multinational company
- Participating in a tender that uses Dun and Bradstreet data
- Completing supplier due diligence or business verification
- Applying for a corporate account, grant or international programme that requests the identifier
- Making the company easier for foreign procurement teams to identify
A DUNS number can support vendor onboarding, but it does not place the company automatically on NIPEX or an operator’s approved vendor list. Read our NIPEX registration guide to understand the separate petroleum supplier qualification process.
Information needed for DUNS registration
Dun and Bradstreet’s current application guidance asks for basic information that can identify and verify the business. Prepare the details exactly as they appear in current company records.
- Legal business name and any trading name
- Physical business address and mailing address
- Business telephone number and a monitored email address
- Name and title of the owner, president or chief executive
- Legal structure, such as a limited company or partnership
- Year the business started
- Primary industry or line of business
- Number of employees at the location
CAC records are useful for confirming the legal name, registration date and address. Dun and Bradstreet may request additional proof when it cannot verify the business with the information supplied.
DUNS requirements and vendor registration requirements are different
Tax clearance, VAT records, NUPRC permits, pension compliance, safety documents, audited accounts and insurance may appear on an oil and gas vendor checklist. They are not all universal requirements for obtaining a DUNS number.
Keep the two files separate. First, provide Dun and Bradstreet with the company information needed to identify the business. Then prepare the wider compliance pack required by the specific operator. Mixing both processes can make a simple request look more complicated than it is.
How to get a DUNS number in Nigeria
1. Search for an existing company record
Use Dun and Bradstreet’s lookup service before starting a new application. A former employee, parent company or business partner may already have requested a number for the same legal entity or location.
2. Confirm the legal company details
Compare the CAC name, physical address, telephone number and leadership details with the information you plan to submit. Decide how any recent change of address or company name will be explained and supported.
3. Submit the request
Complete the official request form with accurate information. Use a company email that the responsible officer checks regularly because Dun and Bradstreet may contact the business to verify the record.
4. Respond to verification questions
Provide any additional document or clarification requested. Keep the response limited to the issue raised and make sure names, dates and addresses remain consistent.
5. Record the number and update supplier profiles
When the number is issued, store it with the company compliance records. Add it to operator portals and tender forms only where requested. The legal entity and location connected to the number should match the supplier that is applying.
How much DUNS registration costs
Dun and Bradstreet states that a standard DUNS number request is free. It also offers faster processing options in some locations for a fee, but the price and availability depend on the service presented during the application.
Avoid anyone who claims the number itself must be purchased or renewed every year. If you want help checking an existing record and completing the request, visit our team. We can guide the process so you do not spend money on duplicate or unnecessary applications.
How long the application takes
Dun and Bradstreet advises allowing up to 30 business days for a standard request. An expedited service may complete the request within about eight business days where that option is available. Verification issues can make either route take longer.
Apply before a tender deadline. A buyer may insist on the issued number and may not accept an application receipt as a substitute.
Does a DUNS number expire
The number does not expire and Dun and Bradstreet does not charge an annual renewal fee for it. The business record can still become inaccurate if the company moves, changes its legal name or alters important ownership and contact details. Ask for the record to be updated when those changes occur.
Common causes of delay
- Submitting a new request when an existing number already belongs to the same entity
- Using a trading name where the form expects the registered legal name
- Providing an address or telephone number that cannot be verified
- Ignoring verification emails or calls
- Submitting different company details to the buyer and Dun and Bradstreet
- Waiting until the tender closing date before starting the request
Using the number for vendor prequalification
Once the number is available, the next task is to satisfy the buyer’s own onboarding rules. Prepare a company profile, statutory compliance records, permits, financial documents, health and safety records, references and the product or service categories requested by that operator.
For petroleum opportunities, the company may also need NIPEX qualification and the correct regulatory permit. Our oil and gas compliance services cover the separate approvals that may sit beside the DUNS record.
Frequently asked questions
Can a Nigerian company obtain a DUNS number
Yes. The system identifies businesses in many countries. The company must provide verifiable legal and operating information for its Nigerian entity or location.
Is a DUNS number the same as a CAC registration number
No. CAC issues the Nigerian company registration number. Dun and Bradstreet issues the DUNS number for business identification in its global system.
Can one group have several DUNS numbers
Different legal entities or business locations within a group may have separate numbers. Do not assume that a parent’s number automatically identifies a subsidiary.
Where should the application be made
Start with the official Dun and Bradstreet DUNS request page. Search for the business before submitting a new request.
Get the business identity right the first time
DUNS registration is straightforward when the company details are consistent and the request reaches a contact who can answer verification questions. The number then becomes a reliable identifier across future supplier and tender profiles.
