Who is Dun & Bradstreet?

Dun & Bradstreet (D&B) is a global business-data company. Its D-U-N-S (Data Universal Numbering System) identifiers help lenders, suppliers, and partners verify that a company is a real, trackable business entity separate from a personal Social Security number.

What you can do here

Use D&B’s directory search to find business listings and D-U-N-S related records. Many vendors and finance partners still ask for a D-U-N-S Number when onboarding suppliers or reviewing credit. U.S. businesses can typically claim or request a number at no charge through D&B’s own flows.

Why check this from WellDoIt

A lender, supplier, or partner asked for your D-U-N-S Number and you need to confirm it.
