How to access the D&B DUNSmanager® to submit updates or launch slow payment disputes.



Business owners often submit trade references to be included in their business credit file only to later find they were not accepted or the data is not being included.

This can be especially frustrating after paying for a service intended to do just that. Unfortunately, one never knows when purchasing the service or uploading their vendors whether they will get accepted or not.

When asked why a trade reference was declined, D&B® representatives are only permitted to reveal five possible reasons:

  • Vendor is not a US-based business

  • Vendor does not have a full D&B® file of their own

  • Vendor is a bank, credit card, utility, or financial institution

  • Vendor already auto-reports into D&B®’s automated system

  • Have failed in six attempts to reach vendor to gather credit history

In reality, there are lots more reasons why a trade reference can be declined or blocked from reporting into your file. In addition to the primary 5 above, here are 20 of the more common reasons your trade reference is not being accepted.

  • Your company and vendor have a common principal

  • Reciprocating submissions (reporting on each other)

  • Vendor contact number disconnected/ rings to different business

  • Vendor’s phone only rings to an answering machine or fax tone

  • The vendor declines to report credit references on their clients

  • The vendor’s callback number is not associated to the business

  • Vendor has too low of payment
