What is a D&B D-U-N-S® Number?

D&B's Data Universal Numbering System (D-U-N-S® Number) is the widely recognized standard for identifying businesses among thousands of companies, marketplaces and regulatory entities.

Created in 1962, the Data Universal Numbering System or D-U-N-S® Number is D&B's copyrighted, proprietary means of identifying business entities on a location-specific basis.

Assigned and maintained solely by D&B, this unique nine-digit identification number has been assigned to over 240 million businesses worldwide.

A D-U-N-S® Number remains with the company location to which it has been assigned even if it closes or goes out-of-business.

The D-U-N-S® Number also "unlocks" a wealth of value-added data associated with that entity, including the business name, physical and mailing addresses, tradestyles ("doing business as"), principal names, financial, payment experiences, industry classifications (SICs and NAICS), socio-economic status, government data and more. The D-U-N-S® Number also links members of corporate family trees worldwide.

The D-U-N-S® Number is widely used by both commercial and US federal entities and was adopted as the standard business identifier for federal electronic commerce in October 1994.

What is an SIC or Industry Code?

Standard Industrial Classification codes were developed by the Federal Government in conjunction with the U.S. business community during the 1930’s. They have proven to be a useful tool for professionals looking to segment domestic markets, analyse customer relationships, and conduct general business research.

SIC Codes divide all major economic activity into ten major divisions. The first two digits describe the nature of this activity in very general terms (i.e. Mining, Construction, Manufacturing). Remaining digits break down these categories into specific products and “sub-industries.”

What is an UNSPSC Code or Product Code?

The United Nations Standard Products and Services Code® (UNSPSC®), managed by GS1 US™ for the UN Development Programme (UNDP), is an open, global, multi-sector standard for efficient, accurate classification of products and services.

The UNSPSC® is a hierarchical convention that is used to classify all products and services. It is the most efficient, accurate and flexible classification system available today for achieving company-wide visibility of spend analysis, enabling procurement to deliver on cost-effectiveness demands and allowing full exploitation of electronic commerce capabilities.

The UNSPSC® was jointly developed by the United Nations Development Programme (UNDP) and Dun & Bradstreet Corporation (D&B) in 1998. It has been managed by GS1 US since 2003.

How does UNSPSC work
XX Segment

The logical aggregation of families for analytical purposes

XX Family

A commonly recognized group of inter-related commodity categories

XX Class

A group of commodities sharing common characteristics

XX Commodity

A group of substitutable products or services

XX Business Function

The function performed by an organization in support of the commodity

All UNSPSC entities are further identified with an 8-digit structured numeric code which both indicates its location in the taxonomy and uniquely classifies it. An additional 2-digit suffix indicates the business function identifier. A structural view of the code set would look as follows:

Category Number
43 Information Technology Broadcasting and Telecommunications Communications Devices and Accessories
Family 20 Components for information technology or broadcasting or telecommunications Computer Equipment and Accessories
Class 15 Computers Computer accessories
Commodity 01 Computer switch boxes Docking stations
Business Function 14 Retail
