NEW: Download The Latest D&B Delist File

Dun & Bradstreet has always prided itself in providing data that is current, comprehensive, and accurate. D&B’s global database of businesses has grown to over 300 million entities. At the same time, accurately identifying companies that meet specific criteria that render them “non-marketable”, is equally important. The result is a regularly updated delist file.

The file is updated on the basis of outreach to the target businesses, as well as in response to businesses that request deletion from the D&B database. In either case the business name is correlated to a specific DUNS number. The resulting file represents a list of Duns #s of non-marketable companies.

NOTE: Non-marketable can mean either of two things:
  • After repeated attempts at contact and verification, the company can’t be marketed to due to certain operating conditions such as undeliverable address, out of business, or other insufficiency in their data records.
  • The company has asked that their data not be included in D&B’s database and is therefore non-marketable.

Since the scope of this effort is global, it is no surprise the list is quite large. As of the last update, the D&B Delist file contained 14,471,077 entries. Imagine the impact mailing to delisted companies can have on a marketing budget, not to mention the exposure to complaints and even GDPR non-compliance. Between wasted money, ill will, and legal exposure the effects can be huge.
