How to Find the DUNS Number for a Company

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.

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.

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.

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.


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