Dun and Bradstreet's Data Universal Numbering System, or DUNS, has become the worldwide standard in business credit management. Over 200 million businesses worldwide use this system during daily business operations. Each company must register with Dun and Bradstreet to acquire a DUNS number. Once a company is in the system, potential customers and service providers may look up the company' financial information to determine further credit limits and business creditworthiness.
