The Data Universal Numbering System (D-U-N-S®) was established by D&B in 1962. It is a unique nine-digit identification assigned to every business in D&B’s Global database.
The D&B D-U-N-S® Number is a widely recognized standard for identifying businesses among thousands of companies, marketplaces and regulatory entities. Companies worldwide use the D-U-N-S® Number to link information about suppliers, customers and trading partners, thereby providing a complete picture of the risk and opportunity in their business relationships.
All companies in the D&B database are assigned a D-U-N-S® Number after they have gone through a rigorous, proprietary process called DUNSRight®.
