The DUNS number, a D and B innovation, came about in 1963 and immediately brought business credit information into the computer age. Today, the DUNS number (Data Universal Numbering System) has become a standard business identifier for governments and agencies throughout the world. It has helped Dun and Bradstreet remain the undisputed leader in the international information industry.

The DUNS number is just another example of how D and B has sought to improve business credit information over the past 150-plus years. They have clearly worn the hats of innovator and leader in the use of the various developments in communications and computing technology. Currently, the information contained in Dun and Bradstreet's database is used by 99 percent of the lending institutions that offer application only financing programs.

People sometimes confuse the EIN number (Entry Identification Number) with the DUNS number. The EIN base for an organization, corporation, etc. is the IRS Tax ID number, while for individuals it is their social security number (both are nine digit numbers). Organizations and individuals submitting applications to a lending institution must correctly identify the EIN from the DUNS number, since both are nine digit numbers. If they are not correctly identified in the application, the result might be a delay in the issuance of funding.

The bottom line is, if you want to register your business, a DUNS number is required. Without it, you can't operate. In order to register a DUNS number for your fledgling company, it helps to have good business credit. You can start building good business credit by paying all your bills on time and in full.
