How to Get a D-U-N-S Number for Free in 2026

A U.S. business can get a D-U-N-S Number for U.S. business can get a D-U-N-S Number for free by searching Dun & Bradstreet’s database, confirming that no number already exists and submitting accurate legal and location information.

The standard application is free, but Dun & Bradstreet may charge for optional expedited processing. Normal processing can take up to 30 business days, so businesses should apply before a lender, supplier, corporate customer or platform deadline arrives.

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

A D-U-N-S Number is a unique nine-digit identifier issued by Dun & Bradstreet to a business location.

D-U-N-S stands for Data Universal Numbering System. Dun & Bradstreet uses the number to identify a company and connect it with information in its business database.

The number helps distinguish one business from another when companies have similar names. It can also separate individual locations belonging to the same organization.

A D-U-N-S Number is not the same as:

• An Employer Identification Number
• A Social Security Number
• A state business registration number
• A sales tax permit
• A business license
• A SAM.gov Unique Entity ID
• A personal or business credit score

An EIN identifies a business for federal tax purposes. A D-U-N-S Number identifies a business within Dun & Bradstreet’s commercial database.

Does Every Small Business Need a D-U-N-S Number?

Not every small business must have one.

A freelancer, sole proprietor, or local service company can often operate without a D-U-N-S Number. The number becomes more useful when another organization asks for it or when the business wants to establish a record with Dun & Bradstreet.

A business may need or benefit from a D-U-N-S Number when it plans to:

• Apply for credit with certain lenders or suppliers
• Establish a Dun & Bradstreet business credit file
• Work with a corporation that requires vendor verification
• Complete registration with a platform that uses D-U-N-S data
• Apply for certain grants outside the federal SAM.gov system
• Present a consistent business identity to potential partners
• Separate multiple business locations in commercial databases

The requirement depends on the organization requesting the number. A business should confirm the exact requirement rather than assume that every loan, vendor account, or registration process needs it.

Is a D-U-N-S Number Really Free?

Yes. Dun & Bradstreet offers a standard D-U-N-S Number application without a fee.

Applicants may see paid products or an optional expedited service during the process. Purchasing those services is not required to receive the number through the standard process.

The free application may take up to 30 business days. A business facing an urgent deadline may be offered paid expedited processing, which can reduce the expected delivery period.

The number does not require an annual renewal fee. Dun & Bradstreet also provides a way for businesses to review and request updates to their company information without paying for a new number.

Owners should make sure they are using the official Dun & Bradstreet process. Third-party websites may charge to complete an application that the business can submit directly for free.

What Information Should You Prepare?

Gather the correct business information before opening the application.

Dun & Bradstreet may ask for details that help identify the organization and confirm that it is a real business. The information required can vary according to the business type and application path.

Prepare:

• Legal business name
• Trade name or DBA, when applicable
• Physical business address
• Mailing address, if different
• Business telephone number
• Business email address
• Website, when available
• Business structure
• Year the business started
• Number of employees
• Owner, officer, or executive name
• Primary industry or business activity
• State registration information
• EIN, when applicable

The legal name should match the name recorded on official registration or tax documents. A DBA should be entered separately when the business publicly operates under another name.

A business that has not selected a stable name should settle that issue before creating inconsistent records across financial and commercial databases. The guide on choosing a business name that works online explains the naming checks that should happen before a company builds its public identity.

How Do You Check Whether a Number Already Exists?

Search Dun & Bradstreet’s database before submitting a new request.

A business may already have a D-U-N-S Number even when the owner never applied personally. Dun & Bradstreet can create or receive business records from public registrations, suppliers, financial activity and other commercial sources.

The initial search normally uses the business name and ZIP code. Search carefully using:

• The full legal name
• The DBA or trade name
• Previous business names
• The current ZIP code
• A previous address, if the business moved
• Common spelling variations

Review the address and business details before claiming a possible match. A similar name does not prove that the record belongs to the applicant.

Creating another record when one already exists can produce duplicate business identities. Duplicates may cause confusion when suppliers, lenders, or partners review the company.

When an existing record belongs to the business, follow the process to claim or manage that record rather than applying for an additional number.

How Do You Apply for a Free D-U-N-S Number?

Start through Dun & Bradstreet’s official D-U-N-S application page.

The process generally follows these steps.

1. Select the correct business location

Choose the application path for a U.S.-based business. International businesses may need to use the Dun & Bradstreet service for their country or region.

2. Search for the business

Enter the business name and ZIP code. Review possible matches before continuing.

When the correct company appears, follow the instructions to access or update that record. Continue with a new request only when no correct match exists.

3. Complete the business information

Enter the legal name, address, contact details, business structure, industry, and other requested information.

Use the physical location where the business operates. A mailing address may not always serve as a substitute for the actual business location.

Home-based businesses can still apply, but they should enter information accurately and follow any additional validation instructions.

4. Review optional services carefully

The application may present paid services, credit-monitoring products, or expedited processing.

Read each selection before continuing. A business does not need to purchase an optional product to receive a standard D-U-N-S Number.

5. Submit the request

Check every field before submitting. Incorrect names, addresses, telephone numbers, or ownership details may slow the authentication process.

Save the confirmation information and monitor the email address used for the request.

How Does Dun & Bradstreet Verify the Business?

Dun & Bradstreet may contact the applicant to validate the submitted information.

The company may check details against public records, business registrations, telephone information, online sources, or documents provided by the applicant.

An applicant should be ready to confirm:

• The legal business name
• The physical location
• The mailing address
• The owner or responsible contact
• The business activity
• The telephone number
• The relationship between the applicant and the company

Use an email address and telephone number that the business monitors regularly. Missing a validation request can delay completion.

The information should also remain consistent. For example, an application using one legal name while the state registration shows another may require an explanation or correction.

How Long Does It Take to Receive the Number?

Standard processing can take up to 30 business days.

Some applications may finish sooner, but owners should not rely on a faster result when working toward a deadline.

Optional expedited service may provide the number within eight business days after a successfully completed application. The expedited option costs money and is not necessary for applicants who can wait for normal processing.

Several issues can delay the request:

• Duplicate business records
• Incorrect legal names
• Incomplete addresses
• Unanswered verification calls
• Unmonitored email accounts
• Conflicting public information
• Missing registration details
• Difficulty confirming the physical location

Apply early when a lender, vendor, customer or platform requires the number. Waiting until the final week can create unnecessary pressure.

Do Sole Proprietors and Home Businesses Qualify?

Yes. A business does not need to be an LLC or corporation to request a D-U-N-S Number.

Sole proprietors, home-based companies, independent businesses, and larger organizations may qualify when they provide verifiable business information.

A sole proprietor should identify the business structure correctly. When the business uses the owner’s legal name, the record may reflect that name. When it uses a registered DBA, both the legal owner information and trade name may be relevant.

A home address may serve as the physical business location when the company genuinely operates there. The applicant should not invent a commercial location or use an unrelated address merely to make the business appear larger.

Does Each Business Location Need a Separate Number?

Dun & Bradstreet can assign a separate D-U-N-S Number to each physical business location.

A company with one location normally needs one number for that location. A company with several branches, offices, warehouses, or stores may have separate numbers connected within the same corporate family.

Do not request multiple numbers for different departments operating at the same address unless Dun & Bradstreet’s process specifically requires separate records.

Before applying for a second location, search the database and determine whether that branch already has a number.

The information for each location should accurately identify:

• Its physical address
• Its telephone number
• Its operating status
• Its relationship to the main company
• Its local business activity

This structure helps other companies identify the exact location they are evaluating.

Does Getting a D-U-N-S Number Build Business Credit?

A D-U-N-S Number can help establish the business’s identity with Dun & Bradstreet, but the number alone does not create strong business credit.

A business credit profile becomes useful when it contains accurate company information and meaningful payment experiences. Vendors, lenders, and other companies may report payment activity, but not every account automatically reports to Dun & Bradstreet.

Getting the number is therefore an identification step, not a shortcut to a high credit score.

A company still needs to:

• Pay financial obligations on time
• Keep registration information accurate
• Separate business and personal finances
• Work with vendors that report payment activity
• Monitor its business credit records
• Correct inaccurate company information
• Avoid unnecessary late payments

Owners should be cautious of services promising an instant high business credit score merely because they can obtain a D-U-N-S Number.

Is a D-U-N-S Number Required for Federal Contracts?

No. The federal government no longer uses the D-U-N-S Number as its official entity identifier for SAM.gov registration.

Businesses that want to bid directly on federal contracts or apply for federal awards generally need a Unique Entity ID issued through SAM.gov.

The SAM.gov Unique Entity ID:

• Contains 12 alphanumeric characters
• Comes directly from SAM.gov
• Is free
• Is assigned during entity registration or a UEI-only request
• Is separate from the nine-digit D-U-N-S Number

A business may still have both identifiers. The D-U-N-S Number may support commercial credit or private vendor requirements, while the Unique Entity ID supports federal award and contracting processes.

Do not pay a third party merely to obtain a SAM.gov Unique Entity ID. SAM.gov provides the identifier without a fee.

What Should You Do After Receiving the Number?

Save the confirmation email and record the number in a secure business file.

Then review the business information associated with the record. Confirm that the name, address, telephone number, ownership details, and industry information are correct.

The business should also:

• Share the number only when a legitimate organization requests it
• Keep a record of which applications use it
• Update the company profile after major changes
• Avoid applying for another number after moving
• Check for duplicate records
• Monitor the company’s business credit information
• Correct inaccurate information promptly

Moving the business does not automatically mean it needs a new number. Update the existing company information unless the move creates a genuinely separate business location.

What Mistakes Should You Avoid?

Paying for the standard application

The regular D-U-N-S Number request is free. Paid expedited processing and other commercial services are optional.

Applying without searching first

A duplicate record can divide or confuse the company’s commercial identity.

Entering a brand name as the legal name

Use the legally registered name in the correct field and enter the DBA separately when requested.

Confusing D-U-N-S with an EIN

An EIN serves federal tax identification purposes. A D-U-N-S Number identifies a business within Dun & Bradstreet’s system.

Using D-U-N-S for federal registration

Federal award applicants should use the SAM.gov Unique Entity ID process.

Assuming the number guarantees credit approval

Lenders and vendors consider many factors. A business identifier does not replace revenue, payment history, financial records, or creditworthiness.
