What is a DUNS Number?


A DUNS number is a unique nine-digit identification number that is assigned by Dun & Bradstreet (D&B) to businesses, organizations, and government entities. It stands for "Data Universal Numbering System" and is widely used as a standard business identifier in the United States and around the world. The DUNS number is used to maintain a comprehensive database of businesses and their financial performance, which is used by credit agencies, lenders, and other organizations to evaluate creditworthiness, risk, and financial stability.

The primary purpose of a DUNS number is to facilitate business-to-business (B2B) transactions, especially those involving credit or financing. A DUNS number allows businesses to establish credit with suppliers, obtain loans and financing, bid on government contracts, and participate in other financial transactions. It also helps businesses to establish credibility and visibility in the marketplace by providing a standardized identifier that is recognized by other businesses and organizations.

How Are DUNS Numbers Used?

DUNS numbers are used by businesses and organizations to establish creditworthiness, track their financial performance, and provide other organizations with a standardized way to identify and learn about them. Here are some specific ways that DUNS numbers are used:

  • Creditworthiness: DUNS numbers are used by credit reporting agencies, lenders, and other organizations to assess the creditworthiness of a business or organization. Having a DUNS number can help businesses establish credit and secure financing.
  • Business identification: DUNS numbers are used by government agencies, suppliers, and other organizations to identify businesses and track their activities. For example, the federal government requires businesses to have a DUNS number in order to bid on contracts.
  • Business intelligence: DUNS numbers provide a standardized way for organizations to access and share information about businesses. This can include financial data, industry classifications, and other key information that can help organizations make informed decisions.
  • Compliance: DUNS numbers are sometimes used to verify compliance with regulatory requirements. For example, some government agencies require businesses to have a DUNS number in order to apply for licenses or permits.

Requirements for Businesses Applying for A DUNS Number


Even though applying for a DUNS number is free and fairly simple, there are some simple things a business should have handy before applying:

  1. Business registration: The business must be legally registered with the appropriate government agencies. This typically involves obtaining a business license or registering with the Secretary of State's office.
  2. Physical address: The business must have a physical address where it conducts its operations. A post office box is not sufficient.
  3. Phone number: The business must have a phone number that can be verified.
  4. Legal structure: The business must have a legal structure, such as a sole proprietorship, partnership, LLC, or corporation.
  5. Credit history: The business must have some credit history, even if it's just a few accounts.
  6. Financial statements: The business may be required to provide financial statements or other documentation to verify its financial stability.
  7. Tax ID number: The business must have a tax identification number (TIN) or employer identification number (EIN) assigned by the IRS.

It's important to note that not all businesses are eligible for a DUNS number. For example, non-profit organizations, government agencies, and individual sole proprietors may not be eligible. Additionally, businesses located in certain countries may have different requirements for obtaining a DUNS number.

Tips for A Successful DUNS Number Application

It may seem as simple as filling out the application and waiting for your result, but there are a few key things you can do to help ensure your application is a successful one. Here are 7 of them:

  • Check for existing DUNS number: Before applying for a DUNS number, check to see if your business already has one.

  • Respond to follow-up inquiries: If the credit reporting agency has any follow-up inquiries or requests for additional information, respond to them promptly and thoroughly.

  • Be patient: The DUNS number application process may take several days or even weeks to complete. Be patient and allow enough time for the application to be processed.

Who Requires A DUNS Number?

You’ve learned all about how to apply for a DUNS number and how advantageous it can be for your business. However, there are some scenarios in doing business where a DUNS number is actually required. Here are some examples:

  • Government contractors: Businesses that want to bid on government contracts or apply for grants from federal agencies are often required to have a DUNS number.

  • International trade: If you plan to do business with companies or organizations outside of the United States, you may need a DUNS number to register with the International Organization for Standardization (ISO) or other international trade groups.

  • Credit reporting agencies: Credit reporting agencies, such as Experian, Equifax, and TransUnion, may use a DUNS number to identify a business when it applies for credit.

  • Business credit issuers: Some credit card companies, such as American Express and Discover, may use a DUNS number to verify a business's creditworthiness before issuing a credit card.

  • Other businesses: Some businesses may require their suppliers or partners to have a DUNS number to ensure that they are legitimate and have a good credit history.

How Does a DUNS Number Impact a Business Credit Report?

A DUNS number can have a significant impact on a business credit report. Business credit reporting agencies, such as Dun & Bradstreet, Experian, and Equifax, use a business's DUNS number to identify and track its credit history.

When a business applies for credit, the lender may check the business's credit report to assess its creditworthiness. The credit report includes information about the business's credit history, payment history, outstanding debts, and other financial data.

Having a DUNS number can help ensure that the credit report is accurate and complete. It can also help establish a credit history for the business, which is important when applying for loans, credit lines, and other forms of financing.

Businesses with a DUNS number may also be eligible for credit products that are specifically designed for businesses, such as business credit cards and lines of credit. These products may offer more favorable terms and lower interest rates than personal credit products.

Finally, a DUNS number can help businesses build credibility with suppliers, partners, and customers. Suppliers and partners may use a business's DUNS number to verify its legitimacy and creditworthiness, while customers may see a DUNS number as a sign of professionalism and stability.

A DUNS number isn’t required for businesses in most scenarios, but can definitely give your business a lift up when it comes to credit-related opportunities.


What If I Don’t Have A DUNS Number For My Business?

It is apparent that a DUNS number brings many benefits to your business. What are the drawbacks if you don’t have one? Here are a few we found:

  • Limited access to government contracts: If your business does not have a DUNS number, it may not be eligible to bid on government contracts or apply for grants from federal agencies.
  • Limited access to business credit: Without a DUNS number, your business may have difficulty establishing a credit profile or accessing credit products that are specifically designed for businesses.
  • Limited credibility with suppliers and customers: Not having a DUNS number may make it more difficult to establish trust with suppliers and customers, who may see a DUNS number as a sign of professionalism and stability.
  • Limited visibility: Without a DUNS number, your business may not be included in D&B's database of businesses, which can limit your visibility to potential partners, suppliers, and customers.
  • Limited benchmarking: Without a DUNS number, your business may not be able to access benchmarking tools that allow you to compare your performance against industry standards and your competitors.

Is a DUNS Number the Same as a Federal Tax ID Number?

A federal tax ID number, called your employer identification number (EIN), and a DUNS number serve different functions and are used for unique business purposes.

The EIN, provided by the IRS, acts as a taxpayer ID for businesses. It's essential for filing business taxes and is also used when setting up a business bank account, obtaining a business credit card, or securing a business loan. Some businesses must obtain an EIN for taxation reasons.

Conversely, a DUNS number is designed for other businesses and potential lenders to evaluate your company's financial standing. It's unrelated to taxation and isn't a legal requirement for businesses. However, certain contracts, grants, or loans may necessitate its possession.

Bottom Line

All in all, a DUNS number is only beneficial to your business, it is free and simple to apply for one, and it can provide you with credit opportunities your business may not have otherwise.
