Entity and Hierarchy
It starts with our universal identifier – the Dun & Bradstreet D-U-N-S® Number – which is assigned once our patented identity resolution process identifies a company as unique within our Data Cloud. From here, our corporate hierarchies provide a picture of an entire organization and its related entities.
Corporate Hierarchies and Linkage
The universal standard for business identification
Dun & Bradstreet D-U-N-S Number is a unique global business identification system that identifies, validates and links to more than hundreds of millions of businesses worldwide. Only D&B assigns the D-U-N-S Number ensuring accuracy, timeliness and cross-border consistency of information.
Discover the value of interconnected relationships
D&B global corporate hierarchies and linkage enable you to see and maintain a family tree and hierarchical structure for your commercial relationships. And because corporate relationships are constantly changing due to ongoing mergers, acquisitions, reorganizations and consolidations, D&B makes daily updates to corporate hierarchies. This brings transparency to business relationships and enriches your view, enabling you to mitigate risk and find new growth opportunities.
Supporting industry classifications and standard geographies
Dun & Bradstreet incorporates Standard Industrial Classification (SIC) as a global industry standard for classifying what a business does. Our proprietary SIC + 4 codes add deeper granularity at the sub-industry and line-of-business level. D&B also supports the International Organization for Standardization (ISO) country codes and utilizes global address standardization processes to standardize local data to local postal standards. This allows you to understand industry segmentation and geography definitions through a globally consistent coding structure.
