Dun & Bradstreet Numbers


Tier II reporting requires companies to gather various information, including the Dun & Bradstreet (D&B or DUNS) number. This unique nine-digit code is often overlooked for completing the report.

What is the Dun & Bradstreet Number?

  • The D&B or DUNS number is a unique nine-digit identification code assigned to companies by Dun & Bradstreet, a business information company.

  • This code is company-specific, meaning your entire company will have a single, unique D&B number.
