DUNS Number Verification Delayed: What to Do Next

Common Causes of Delay

Delays are rarely random — they almost always trace back to something specific making automated verification harder than usual.

• Business too new to appear in registries. If your incorporation or registration was very recent, government databases D&B checks against may not have fully updated yet.
• Minor name or address mismatch triggering manual review. Rather than an outright rejection, a small inconsistency can simply push your application into a slower, human-reviewed queue.
• International or cross-border verification. Confirming a business registered outside the country D&B is processing from can take longer due to additional cross-checking.
• High application volume. Processing queues can back up during particularly busy periods, extending timelines industry-wide rather than for any one applicant.
• Sole proprietors or individuals without formal business registration. These often require additional documentation to confirm the business exists as a distinct entity, which takes extra time to review.

What You Can Check Yourself While Waiting

1. Re-read your submitted application for mismatches. Compare what you entered against your official registration documents — a small formatting difference could explain a manual-review delay.
2. Check your email (including spam/junk). D&B may have already reached out requesting additional information, and a missed message can look identical to a stalled application.
3. Confirm your business registration is fully processed. Search your business in the relevant government registry yourself to confirm it's fully searchable, not just filed.
4. Search for an existing DUNS number. In rare cases, what looks like a stuck new application is actually because a number already existed — see our Duplicate DUNS Numbers guide if that's the case.

When and How to Contact D&B Support

Once you've passed the typical processing window for your application method — and confirmed there's nothing obviously mismatched on your end — reaching out directly is the right next step rather than continuing to wait indefinitely.

• Have your application reference or confirmation number ready if you received one when you first applied.
• State your business's legal name and the date you applied clearly, so support can locate your specific submission quickly.
• Ask directly whether your application requires anything further from you — sometimes a delay is waiting on a document request you haven't seen yet.
• Keep a record of your communication in case you need to follow up again.
