To register for a Dun & Bradstreet, or D-U-N-S number, apply using the D&B D-U-N-S Request Service on the website dnb.com. This nine-digit number is free to any business that is required to register for federal contracts or grants.
To complete the registration for a D-U-N-S number, enter the business' legal name, the Doing Business As name, if applicable, and the business' address. Include the mailing address if it is different from the physical address. Add the business' phone number, the number of employees at the physical location, and a contact name. Also indicate whether the company is a home-based business on the form. Dun & Bradstreet typically issues the number within one business day.
