In 1962, Dun and Bradstreet—a credit company—established the Data Universal Numbering System (DUNS). This unique numbering system links more than 280 million businesses worldwide. A DUNS number is a 9-digit identifier that can be assigned to all business types within all industries. Corporations, sole proprietors, nonprofits, and government offices can all use DUNS numbers. Learn more about a DUNS number—and how it can help your business. Why Do I Need a DUNS Number? There are many uses for a DUNS number that prove its value. Because there is no cost to requesting a DUNS number, you may want to acquire one now so you have it when the need arises. A few examples of when you will need a DUNS number include: \tIf your business wants to pursue government contracts and federal work. \tIf your business is applying for grants through the federal government (especially the US Office of Management and Budget, or OMB). \tIf you plan to expand your business globally—and especially if you plan to work with national governments. Some United Nations offices require DUNS numbers when submitting contracts. Many American business owners use an Employer Identification Number (EIN) from the IRS as an identifier. While an EIN is useful, it is limited to the United States. A DUNS number can be shared globally, providing greater value as your organization expands. Furthermore, an EIN only identifies the business owner, while a DUNS number identifies the business as a whole. How Do I Get My DUNS Number? You can request a DUNS number from the Dun and Bradstreet Corporation. There is currently no cost to request a number, and the company prides itself on its ability to deliver numbers to companies quickly. You can receive your number in about 30 business days, but the company offers some options to expedite the process. If you work for an organization that might already have a moniker, you can use the DUNS number lookup to see if your business is already registered. You can also look up other companies to see if they have registered as well. Can I Use My DUNS Number Instead of My Social Security Number? A DUNS number is not a replacement for an EIN or Social Security number (SSN) for lending and application purposes. When you apply for a business credit card or loan, you will need to provide your EIN and possibly your SSN because a business cannot apply for credit, but a business owner—or authorized treasurer—can. DUNS numbers serve as supplemental identifiers. To prove your identity, you will need to share additional information.
