Mini-Investigation Guide

Mini-Investigation is a standardized service that allows customers to request, track, and receive results of a business investigation. Submitted requests are sent to Dun & Bradstreet or partner offices around the world to research and verify the information.

Mini-Investigation is available for both U.S. and Non-U.S. records.

A separate contract is needed if you intend to use the Mini-Investigation service.

The D&B Direct+ Mini-Investigation API provides the same functionality available on the Mini-Investigation Portal (https://miniinvestigations.dnb.com/).

Service Description

Mini-Investigation processing includes in-depth checks of public information sources and telephone calling to confirm business operations and gather information necessary to create a new record.

The following data elements are collected through Mini-Investigation:

  • Business Name/Trade Style
  • Year Started
  • Physical/Mail Address
  • Number of Employees
  • Telephone Number
  • Sales Figure
  • Line of Business/SIC
  • One Level Up Linkage (When Applicable)

Output for Mini-Investigation includes a D-U-N-S Number®, if the matching effort is successful, and a Resolution Code. If a Mini-Investigation results in creation of a new record, the data for that record may be retrieved from the D&B Database approximately 14 days after the Mini-Investigation is completed.
