Obtaining a DUNS number is absolutely Free for all entities doing business with the Federal government. This includes grant and cooperative agreement applicants/prospective applicants and Federal contractors. Be certain that you identify yourself as a Federal grant applicant/prospective applicant.

The DUNS Company Lookup method searches the Dun and Bradstreet database for a company match. The search can be made essentially by the company's DUNS number but other parameters can be used as well. For example: company name, email address, postal code, and so on.

No business is legally required to have a DUNS number. But it's used by other businesses and potential creditors to assess your company's financial health — which means having one is still necessary for most businesses.
