How to Update Your DUNS Number Details in Nigeria 2026

Last Updated: July 14, 2026

Your business has changed. Your DUNS record hasn't.

Maybe you moved offices. Changed directors. Rebranded. Grew from 5 to 50 employees. Whatever it is — if your D&B record still shows the old information, that's what banks, clients, and government agencies see when they look you up.

Here's how to fix it.

Why Outdated DUNS Information Hurts Your Business

Your DUNS number is permanent, but the business profile attached to it is not static. Dun & Bradstreet uses your record to build your D&B business credit file — the same file that lenders, international clients, and procurement officers check before doing business with you.

An outdated record creates real problems:

Vendor verification failures — A client's compliance team checks your address and it doesn't match. They flag your application.
Loan application delays — A bank sees a director who left two years ago still listed as active. They ask questions.
Tender rejections — Government procurement portals cross-check DUNS records. Mismatches cause rejections.
Damaged credibility — An international partner looks up your business and sees a company that appears to have moved or changed without updating its records.

Keeping your D&B profile current is not optional if you're using your DUNS for serious business.

What You Can Update on Your DUNS Record

Field	Notes
Business legal name	Must match updated CAC certificate
Trading / DBA name	No CAC requirement
Registered address	Must be verifiable
Phone number	Active business number
Email address	Active business email
Number of employees	Self-reported, D&B may verify
Annual revenue	Self-reported, D&B may verify
Industry / SIC code	Based on primary business activity
Ownership structure	Requires documentation
Director details	Requires updated CAC Form 7
Parent company	Requires documentation
Website URL	No documentation required

When You Must Update Immediately

You've moved offices Your DUNS is tied to a physical location. If you've relocated and haven't updated D&B, your record shows a business at an address you no longer occupy. This is one of the most common reasons vendor verification fails.

A director has joined or left New directors, departing directors, change in shareholding — all of these need to be reflected. Banks and investors specifically check director information.

You've rebranded or changed your legal name If your CAC certificate now shows a different name, your D&B record must match. A mismatch between your CAC and your DUNS record is a red flag that triggers additional scrutiny.

Your business has grown significantly Updating employee count and revenue figures improves your D&B credit score and business credibility. A company that still shows "2 employees" when it now has 40 looks suspicious.

Your contact details have changed D&B verifies businesses by calling or emailing. If those details are wrong, verification fails and your record gets flagged as unverifiable.

Common Problems With DUNS Updates

Updates rejected without explanation D&B's rejection messages are often vague. The most common reasons: document doesn't match the existing record exactly, document is older than 3 months, or the business name on the document differs slightly from what's on file. We know what they're looking for.

Lost account access If the person who registered the DUNS has left your company and you can't access the D&B account, you'll need to go through account recovery. This requires proof of business ownership and takes additional time.

D&B overrides your update with third-party data D&B collects data from multiple sources. Sometimes after you update your record, a third-party data provider pushes conflicting information and D&B reverts your changes. This requires a formal dispute to lock your record against third-party overwrites.

Address not recognized Nigerian addresses sometimes don't match D&B's address validation system. This causes updates to fail even when the address is correct. There's a specific way to format Nigerian addresses for D&B submissions.

Frequently Asked Questions

Q: Can I update my DUNS number itself (the 9 digits)? A: No. The 9-digit number is permanent. You update the business information attached to it.

Q: My business moved from Lagos to Abuja. Do I need a new DUNS? A: No — update your existing record with the new address. You only get a new DUNS if you're registering a separate business location (branch or subsidiary). Each location gets its own DUNS.

Q: How do I know what my current D&B record shows? A: Search your business at D&B Business Directory and review the public record. Compare it against your current CAC details.

Q: Can a third party change my DUNS record without my knowledge? A: Yes. D&B collects data from public records, trade directories, and data providers. Incorrect information can appear on your record from these sources. You can dispute and correct it.

Q: Does updating my DUNS affect my D&B credit score? A: Keeping information accurate and current generally improves your D&B rating. Outdated or inconsistent information signals instability and can lower your score.

Q: I need to update multiple things — address, directors, and revenue. Is that one fee? A: Contact us for a quote. Multiple updates in one submission are more efficient and we price accordingly.

Q: What if D&B reverts my changes after I update? A: This happens when third-party data sources push conflicting information. We handle the dispute process to lock your record.
