Data Universal Numbering System
The Data Universal Numbering System, abbreviated as DUNS or D-U-N-S, is a proprietary system developed and managed by Dun & Bradstreet (D&B) that assigns a unique numeric identifier, referred to as a "DUNS number" to a single business entity. It was introduced in 1963 to support D&B's credit reporting practice. It is standard worldwide. DUNS users include the European Commission, the United Nations, Google, and Apple. More than 50 global industry and trade associations recognize, recommend, or require DUNS. The DUNS database contains over 300 million entries for businesses throughout the world. DUNS numbers can be represented using ISO/IEC 6523 using ICD 0060.
