A Data Universal Number System (D-U-N-S) number is a 9-digit designation provided to companies or organizations through Dun & Bradstreet (D&B), a company that researches businesses and provides information on them for credit or other decisions. Companies often elect to get a D-U-N-S number for use in international business, and many non-profit organizations apply for the number so that they can bid for grants or contracts from the US government.

  1. Obtaining a D-U-N-S number can have numerous benefits for your business. It verifies that your business is in operation, and places you on a detailed directory listing which is available to other organizations to look through. You will be placing information about your business, including the address, contact information, and business structure, onto a well-known directory.
    • Having a D-U-N-S number can boost your company's credibility, potentially opening new lines of credit as well as enabling your business to expand.
    • For example, having a D-U-N-S number is required to apply for a government contract, and in some instances, do business abroad.
    • It is possible to register through D&B for free. [1]
  2. Make sure your organization has not already been assigned a number before you go any further with the application. If you bought the business, it may well have already been registered. You can check this quickly online by visiting the official Dun & Bradstreet website and searching for your company. You can type in the name and location of your business and you will see whether or not you have a D-U-N-S number.
    • Since the numbers are unique and site-specific, they stay with the organization, even if the organization is closed, and they are never assigned again.
