DUNS Number

Definition

A DUNS (Data Universal Numbering System) number is a unique nine-digit identifier assigned to businesses by Dun & Bradstreet (D&B). It is used to establish a business credit file and is required for many business activities including applying for government contracts, obtaining certain business loans, and building business credit. Every physical location of a business can have its own DUNS number. Obtaining a DUNS number is free and can be done through the Dun & Bradstreet website. Once established, the DUNS number links to the business's D&B credit profile, which tracks payment history, credit utilization, and public records.

Example

A new LLC applies for a free DUNS number through dnb.com. Within 30 days, they receive their 9-digit number and can begin building their D&B business credit profile by opening trade accounts that report to D&B.
