In today’s data-driven world, having a unique identifier is essential for businesses looking to grow, gain credibility, and operate internationally. One such identifier is the Data Universal Numbering System (DUNS) number, a nine-digit code used to verify and track businesses worldwide. This guide covers what a DUNS number is, how to get one, and how it can help your business thrive.
What Is a DUNS Number?
A DUNS number is a unique, nine-digit identifier assigned to a business by Dun & Bradstreet (D&B). Unlike tax identifiers like the EIN (Employer Identification Number), which are issued by the IRS, a DUNS number is used primarily for business credit profiling, government contracting, and global business verification.
Each Data Universal Numbering System Number is linked to a specific business location, enabling D&B and other organizations to maintain accurate, location-specific business information.
Why a DUNS Number Matters
Global Recognition
The DUNS number is recognized by:
- The U.S. Federal Government
- The United Nations
- The European Commission
- Global corporations conducting supplier vetting and compliance checks
It is a requirement for businesses seeking U.S. federal contracts or grants and is often used internationally for due diligence and supply chain management.
Business Credibility
Having a Data Universal Numbering System Number enhances your professional image. It shows that your business is verified, trackable, and engaged in transparent operations.
Access to Contracts and Funding
Many public and private entities require a DUNS number during the application process for contracts, loans, or grants. For example, businesses registering on the System for Award Management (SAM.gov) for U.S. government contracts previously needed a DUNS number (recently replaced by UEI, though DUNS is still widely used globally).
Business Credit Profiling
D&B uses your DUNS number to create a credit file. Lenders, suppliers, and partners may review this report before entering into agreements, making it critical for establishing business creditworthiness.
How to Apply for a DUNS Number
The application is straightforward and free for businesses needing it for U.S. government grants or contracts.
Step-by-Step Process:
- Go to the Dun & Bradstreet official website.
- Click on “Get a D-U-N-S Number.”
- Search for your business to see if it’s already listed.
- If not listed, proceed with the online application.
- Provide required details including legal name, address, type of business, and contact info.
- Submit the form and wait for verification.
- Once verified, you’ll receive your DUNS number via email, typically within 1–3 business days.
For international businesses, the process may vary slightly based on the local D&B office.
Example
Elena Alvarez, owner of a New York-based IT consulting firm, applied for a federal contract to modernize a small agency’s cybersecurity systems. One of the eligibility requirements was a DUNS number. After obtaining it through D&B, not only did she qualify for the contract, but she also began receiving partnership requests from larger firms that found her through the DUNS database. Her business profile was now visible to entities conducting due diligence worldwide.
Common Misunderstandings
DUNS vs. EIN
While both are identifiers:
- EIN is issued by the U.S. IRS for tax reporting purposes.
- DUNS is issued by D&B and used for business credit and global identity verification.
They serve different functions and are not interchangeable.
Is the DUNS Number Obsolete?
In 2022, the Unique Entity Identifier (UEI) replaced the DUNS number for federal contracting in the U.S. via SAM.gov. However, the DUNS remains widely used by:
- Private sector entities
- International businesses
- Banks and commercial lenders
- Supply chain networks
So while not required for new federal registrations, it’s still a valuable identifier for many use cases.
Where Is a DUNS Number Typically Required?
- U.S. federal grants and contracts (prior to 2022 UEI transition)
- International trade compliance
- Business-to-business credit verification
- Supplier onboarding in corporate procurement
- Banking and financing applications
Frequently Asked Questions
Is there a fee to get a DUNS number?
No. If your business is registering for federal grants or contracts, it’s free. For commercial or global use, some premium services may be offered but are optional.
How long does it take to receive a DUNS number?
Usually 1 to 3 business days after verification.
Can a business have multiple DUNS numbers?
Yes. Each physical location or branch can be issued a separate DUNS number.
What happens to the DUNS number after the UEI transition?
It remains valid and usable, particularly outside the federal space. D&B continues to maintain the DUNS database.
