.duns Domain Information

Country flagLogo for .duns Domain

Business identification and credit reference data framed the .duns application in ICANN's 2012 New gTLD Program. The string names a widely used business identifier system rather than a company, which gives it an unusual character: it denotes a piece of commercial infrastructure that other organizations reference in procurement, credit checks, and supplier onboarding.

A namespace tied to an identifier system carries a verification argument stronger than most brand extensions, since lookup and validation pages are exactly the surface where a fraudulent supplier record would be inserted. The extension is not currently active in the DNS root zone and is not available for registration by any party.
