Dun & Bradstreet

Global leader in commercial data and B2B identity, with the most widely adopted business identifier (D-U-N-S Number) and one of the largest business data clouds in the world

Dun & Bradstreet (D&B) is one of the world's oldest and most trusted providers of business data, analytics, and insights. Founded in 1841, the company maintains the D-U-N-S Number — a unique nine-digit identifier assigned to businesses globally — which has become a foundational standard for B2B identity across finance, procurement, supply chain, and advertising. D&B's data cloud encompasses hundreds of millions of business records, enabling clients to verify, enrich, and activate business intelligence at scale. In the AdTech ecosystem, D&B plays a critical role in B2B audience targeting and account-based marketing (ABM). Its Bombora partnership and D&B Audience Solutions allow marketers to reach precise business audiences across programmatic channels using firmographic, technographic, and intent data. The company's Master Data Management (MDM) and data enrichment capabilities help enterprises maintain clean, accurate CRM and marketing databases, directly improving campaign targeting and ROI. D&B went public again in 2020 after a period of private equity ownership, trading on the NYSE under the ticker DNB. The company serves tens of thousands of customers globally across financial services, technology, manufacturing, and professional services. Its data assets, combined with analytics platforms like D&B Hoovers and D&B Finance Analytics, position it as a dominant force in the B2B data and intelligence market, competing with players like Experian, Equifax, and Acxiom in the commercial data space.
