You did everything right—paid for D&B CreditBuilder or Credit Insights, submitted your trade references, and waited for your business credit file to update—only to discover your vendors were declined and nothing is reporting. If that sounds familiar, you’re not alone. The truth is Dun & Bradstreet may share only a short list of “official” reasons, but there are dozens of real-world issues that can block a trade reference from being verified, accepted, and added to your PAYDEX-building history. In this post, we break down 25+ common reasons vendors get declined (from phone and email verification problems to vendor policies and reporting conflicts) and what to do next so you can choose better trade references and build stronger business credit faster.

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.

In this instance, we will use D&B as an example... When asked why a trade reference is 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

• The vendor did not respond to D&B's request to gather credit history

In reality, there are more than 25 reasons for declined vendors. That number is actually closer to 45. D&B is the only one who can tell you why a trade reference can be declined or blocked from reporting into your file. In most cases, your vendors will get declined for simple reasons that have no bearing on your company or how you pay your bills. In addition to the primary 5 above, here are 10 more of the most common reasons:

• Vendor thinks it's a sales call and tells D&B to never call them again and hangs up

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

• The vendor declines to report credit references on any their clients

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

• Vendor refuses to answer one or more of the required questions

• Vendor does not recognize business name as a current customer

• The vendor's email address bounces back as undeliverable

• The only credit history is an unused line of credit

• The vendor’s SIC code deems their company as unqualified

• Vendor is being investigated for suspicious activity or reporting

Only D&B can accurately identify why a vendor has been declined, but they are not required to provide that information and, in most cases, they will not. If the vendor has been declined twice, your best practice is to accept D&B’s determination and submit a different vendor.

LESSON: You'll have to pay for a Credit Insights Plus service to submit your vendors to D&B. Even though there is a possibility your trade references will not get accepted to report into your credit file, it is still far better to give it a try since that is the fastest way to boost your scores and ratings. You'll generally know within 10 days if it was a hit or miss.
