Of course. Applying for a D-U-N-S Number is a free and essential step for businesses looking to establish credit, apply for government contracts, or work with major corporations.

Here is a comprehensive guide to the D-U-N-S Number application process.

What is a D-U-N-S Number?

A Data Universal Numbering System (D-U-N-S) Number is a unique, nine-digit identifier for businesses, provided by Dun & Bradstreet (D&B). It's like a social security number for your company and is used to:

  • Establish a business credit profile.

  • Apply for federal grants and contracts (required by the U.S. government).

  • Apply for business loans and lines of credit.

  • Build trust with suppliers and partners.



Who Needs a D-U-N-S Number?

You should apply for a D-U-N-S Number if you:

  • Plan to bid on U.S. federal government contracts.

  • Want to apply for business loans or credit.

  • Wish to establish a business credit file separate from your personal credit.

  • Are asked for one by a potential partner, supplier, or customer.



The Application Process: Step-by-Step

The primary and recommended way to apply is through the D&B website.

Step 1: Check if You Already Have a Number


Before applying, check if your business already has a D-U-N-S Number. It's common for businesses to be registered without their knowledge.

Step 2: Gather Your Information


The application is straightforward, but having this information ready will make it faster. You will typically need:
  • Legal Business Name: The exact name as registered with your state.

  • Business Address: Physical address (P.O. Boxes are often not accepted).

  • Mailing Address: If different from the physical address.

  • Business Structure: (e.g., Sole Proprietorship, LLC, Corporation, Partnership).

  • Year Business Started / Founded.

  • Industry Type / SIC or NAICS Code.

  • Number of Employees.

  • Contact Information: Name, title, and phone number of the primary contact.

  • Owner/Chief Executive Officer's Name.


Step 3: Choose Your Application Method

Option A: Online Application (Fastest & Free)
This is the standard and most efficient method.

  • Go to the D&B D-U-N-S Number request page: https://www.dandb.com/duns-number/

  • Click "Get A D-U-N-S Number."

  • Fill out the online form with the information you gathered.

  • Review your information carefully for accuracy.

  • Submit the form.


Option B: Phone Application (For U.S. Federal Government Contractors)
If you are specifically applying for a federal grant or contract, you can call the dedicated line.
  • Phone: 1-866-705-5711

  • This service is designed for businesses needing a D-U-N-S Number to register with the System for Award Management (SAM.gov).


Option C: International Businesses
If your business is located outside the United States, you can apply through the D&B global network.


What Happens After You Apply?


  • Verification Process: D&B will review your application and may need to verify the information. They might call you or your business to confirm details. It's crucial to answer this call to avoid delays.

  • Standard Processing Time: The standard processing time is listed as up to 30 business days. However, it can often be faster.

  • Expedited Service: If you need your D-U-N-S Number sooner, D&B offers expedited processing for a fee (often within 5-8 business days). You will be presented with these paid options during the online application.

  • Receiving Your Number: Once your application is approved and processed, you will receive your D-U-N-S Number via email.



Important Tips and Warnings


  • IT IS FREE: The D-U-N-S Number itself is free. Be wary of third-party websites that charge a fee to "apply for you." They are often just reselling a free service. Always start at the official D&B website.

  • Accuracy is Critical: Any errors in your business name, address, or structure can delay the process or create duplicate files. Double-check everything.

  • Answer the Phone: D&B's verification call is a critical step. If you miss it, your application will be delayed.

  • It's Not Instant (Usually): Plan ahead. Don't wait until the day before a grant application is due to request your number.

  • Build Your Profile: Getting the number is just the first step. To build a strong business credit score (Paydex score), you need to have trade references (suppliers or lenders that report your payment history to D&B).



Next Steps After Receiving Your D-U-N-S Number


  • Register on SAM.gov: If you're a government contractor, use your new D-U-N-S Number to complete your registration on SAM.gov.

  • Establish Business Credit: Start building your credit file by applying for credit with vendors who report to D&B.

  • Monitor Your File: Check your D&B business credit report periodically to ensure all information is accurate.
