Five Reasons Your Business Should Have a DUNS Number. Posted on February 18, 2010, 9:55 am, by Robert Mangiafico. A DUNS number is a special number issued by Dun & Bradstreet to track a business so that information about that business can be reported to other institutions. Most businesses get a DUNS number when they are first formed.
A DUNS number, which stands for Data Universal Numbering System, is a free, unique nine-digit number issued by Dun & Bradstreet to a single business entity. Your number is yours alone, even if you go out of business. D&B does not reuse or reissue numbers to a second business.
