What a DUN Report Is
A DUN report is a business credit file maintained by Dun & Bradstreet. It aggregates payment data, public records, and company details into a single profile used by lenders, vendors, and partners to evaluate creditworthiness. The report is built around a unique nine-digit D-U-N-S number assigned to each business location.

Unlike personal credit reports, a DUN report focuses on commercial obligations. It tracks how a business pays suppliers, lenders, and other creditors, and it may include details about industry risk, company size, and payment trends. Because many creditors report to Dun & Bradstreet, the DUN report can become a central reference in B2B credit decisions.
Key Components of a DUN Report
A typical DUN report includes several sections that together paint a picture of a business's financial reliability.
- Company Profile: Legal name, trade names, address, phone number, year established, employee count, and industry codes.
- D-U-N-S Number: The unique identifier linking all data to the specific business location.
- Payment History: Summary of how the business pays trade creditors, often shown as a paydex score or payment trend indicator.
- Public Records: Liens, judgments, bankruptcies, and other filings that affect credit standing.
- Trade References: Details on creditor relationships, including credit limits and payment performance reported by suppliers.
- Financial Statements: Where available, balance sheet and income data submitted by the business or pulled from public filings.
Understanding the Paydex Score
The paydex score is one of the most referenced data points in a DUN report. It ranges from 1 to 100 and reflects a business's payment history with Dun & Bradstreet's trade suppliers. A score of 80 or above generally signals that a business pays on or before terms, while lower scores suggest late payments or delinquencies.
The score is weighted toward recent behavior, so consistent on-time payments can lift it over time. A single late payment can have an outsized impact, particularly for younger businesses with a short credit history. Because the paydex depends on trade data actually reported by creditors, a business with few reported relationships may have a thin or incomplete score.
How Businesses Use DUN Reports
Lenders often pull a DUN report before approving commercial loans or lines of credit. Vendors use them to set payment terms, credit limits, and pricing for new customers. Investors and business partners may request a DUN report during due diligence to assess the financial health of a company they are considering working with.
For the business itself, reviewing a DUN report regularly can catch errors before they cause problems. Inaccurate payment data, outdated company information, or missing trade references can all distort the picture of a company's creditworthiness. Dun & Bradstreet provides a dispute process for correcting errors, though resolution times can vary.
Limitations and Considerations
A DUN report is not the only business credit product. Equifax, Experian, and other agencies maintain separate business files with different scoring models and data sources. A lender may rely on one, several, or none of these reports depending on the industry and the size of the credit request.
Because reporting is voluntary, not all creditors share data with Dun & Bradstreet. A business that pays on time but works with creditors that do not report will have a less complete DUN report than one with broad trade reporting. Additionally, the DUN report reflects historical data and may not capture a business's current cash flow or recent improvements in financial performance.
Accessing and Monitoring Your DUN Report
Businesses can request a free copy of their DUN report through Dun & Bradstreet's website. The report is also available through paid subscription services that provide ongoing monitoring, alerts for changes, and more detailed analytics.
Regular monitoring is especially valuable for growing companies that plan to seek financing, enter new markets, or work with large corporate buyers. A strong DUN report can open doors to better credit terms, lower interest rates, and faster approval processes. A weak or thin report may require time and deliberate effort to build, starting with establishing trade relationships that report to Dun & Bradstreet.
