Definition of the D&B D-U-N-S Number

The D&B D-U-N-S® Number is a unique nine-digit identifier for businesses. It is used to establish a Dun & Bradstreet business credit file, which is often referenced by lenders and potential business partners to help predict the reliability and/or financial stability of the company in question. If you want to bid on government proposals, you will need to get a D-U-N-S Number for each physical location of your business. You can get your D-U-N-S Number expedited for free if you are required to register with the federal government for contracts or grants.
