D-U-N-S® Number

A D-U-N-S Number is a unique 9-digit number identifying a business on which a D&B Credit Report has been generated; and once assigned, is neither reused nor assigned to another business.

The D&B Direct API includes several methods for locating D-U-N-S Numbers. In the event that you are unable to locate a D-U-N-S Number for a particular business, you may request that one be assigned using the Investigation Service.

When supplying a D-U-N-S Number to any of the D&B Direct products or features, do not include any dashes or spaces in the number.

NOTE: DUNS returned in the response will be 9 digit zero-padded numeric value.

For additional information, visit the D&B D-U-N-S Number page.

Family Tree Member Roles

Headquarters Organization, Branch, Division

The term headquarters is used to distinguish business establishments that have branches or divisions reporting to them. Many headquarters companies do not report financial data for branches or divisions; see "trade up indicator" for details related to this scenario.

Parent Organization, Subsidiary, Affiliate

This term parent is used to distinguish corporations that own more than 50% of another corporation's capital stock; these owned companies are subsidiaries to the parent company. Affiliates are related to other businesses through common ownership by the same parent organization.

Domestic Ultimate

This is a term used to indicate the highest level parent within a corporate family tree that is domiciled in the same country as the requested company. A subject may be its own Domestic Ultimate.

Global Ultimate

This is a term used to indicate the highest level parent within a corporate family tree. A subject may be its own Global Ultimate.

Trade Up Indicator

This is an optional parameter on data layer requests that will instruct the web service to return information for the headquarters when the requested organization is a branch.

There are some companies where D&B only collects information at the headquarters level. In these cases, the headquarters information is returned regardless of the trade up indicator value.

There is one other exception to this option, a trade up is not possible if the subject is a foreign branch (defined as being domiciled in a different country than the headquarters). [The D&B Direct web service will respond with a PD006 result code in this situation]

Auto Trade Up Countries

  • A: Automatic tradeup to HQ (no branch delivery)
  • R: Only trades up to HQ on request
  • N: No tradeup to HQ, only branch data delivered
  • U: Branch D-U-N-S unavailable on local host (return error 40604)

Return Only In-Date Indicator

This is an optional parameter available on some data layer requests that will instruct the web service to return information if it is considered to be "in date" based on the date it was last revised.

The D&B Direct web services will respond with a PD004 result code if a request for in-date information is unable to deliver the product.
