Today we're launching 6° of Corporations, a new micro-site that provides some insight into the complicated area of corporate identity. It may sound trivial, but uniquely identifying a corporate entity is not easy. For federal contracting data (like in USASpending.gov), DUNS numbers are used to (supposedly) uniquely identify a contractor. However, there are problems in not only how DUNS numbers are issued and maintained, but also with the agency's use of DUNS numbers. To help illustrate this, we’ve created a visualization that shows the relationship between company names and company DUNS numbers in USASpending.gov.
