Number Guide for Government Contractors and Grantees: DUNS®

About the DUNS® Number
Created in 1962, the Data Universal Numbering System or DUNS® Number is D&B's copyrighted, proprietary means of identifying business entities on a location-specific basis. Assigned and maintained solely by D&B, this unique nine-digit identification code has been assigned to over 84 million businesses worldwide.
DUNS® Number remains with the company location to which it has been assigned even if it closes or goes out-of-business. The DUNS® Number also "unlocks" a wealth of value-added data associated with that entity, including the business name, physical and mailing addresses, trade styles ("doing business as"), principal names, financial, payment experiences, industry classifications (SIC' s and NAICS), socio-economic status, government data and more. The DUNS® Number also links members of corporate family trees worldwide. The DUNS ® Number is widely used by both commercial and federal entities and was adopted as the standard business identifier for federal electronic commerce in October 1994. The DUNS Number® was also incorporated into the Federal Acquisition Regulation (FAR) in April 1998 as the Federal Government's contractor identification code for all procurement-related activities.
