A Data Universal Numbering System (DUNS) number, in many cases, can make or break a company. These unique nine-digit numbers were developed by Dun & Bradstreet, a credit bureau for businesses. If you plan to extend your business, a DUNS number can be used to determine the financial strength and credit worthiness of a company. A DUNS number is also necessary to bid for government contracts. Locating a company's number helps arm you with the information needed to determine whether you should do business with that firm.

Skill level:


  1. 1

    Speak with the chief financial officer (CFO), or person responsible for accounts receivable and accounts payable of the company. These individuals work with the finances and credit of the company; therefore they should have the DUNS number. Ensure there is a necessary reason for needing the company's DUNS number. Also, ask the representative if they are registered with Dun & Bradstreet. If the company is small enough, you may be able to get in contact with the president or CEO.

  2. 2

    Perform a company search using the Business Partner Network. This network is used to find businesses that can work with the government through their approved contracts. Conduct a search by inputting the company's name and address.

  3. 3

    Contact Dun & Bradstreet over the phone or through its website. You will need to know the basic company information such as the full business name; address; phone number; and, in some cases, the federal tax ID number. There is no cost for the DUNS number.

Tips and warnings

  • Some businesses may opt out of registering for Dun & Bradstreet, considering that registration has a cost.
