Duns and Bradstreet is a business analytics company. Other companies use them for, among other things, verifying business entities. You’ll need to be registered with DUNS to get a Microsoft Partner or a Apple Business Manager account. You can apply for your DUNS # and then they’ll be in touch over the phone with a few questions to verify your business.
Once you get your number, keep it on file for registering with Microsoft and Apple.
