About the D&B D-U-N-S Number

The D-U-N-S (Data Universal Numbering System) number is a crucial component of D&B data. A D&B D-U-N-S number is a nonindicative, nine-digit number assigned to each business location in the D&B database. Each D-U-N-S number has a unique, separate, and distinct operation and is maintained solely by D&B. Industries and organizations around the world use the D&B D-U-N-S number as a global standard for business identification and tracking.

Each company has a unique D&B D-U-N-S number associated with it. It acts as a unique identifier for a company in the D&B database.

To uniquely identify the association between different companies in the D&B database, each company also has associated D&B D-U-N-S numbers.

The categories of D&B D-U-N-S numbers include:

  • D&B D-U-N-S Number. Each unique business location listed in the D&B database is assigned a D&B D-U-N-S number. This number is called DUNS Number in your Siebel application.
