It doesn't, but we help people get them on an ad hoc basis.
Mind if I make a guess? You're probably wondering "Can I get a DUNS number so that I can list something on the App Store?" if you're like 90% of people who ask us this. If so, let me just tell you now what we'd tell you in the future:
> My most recent understanding is that if they’re using the DUNS number as a part of the Apple Developer program, we should recommend that they email appdeveloper@dnb.com and they will advise you how to apply for your situation. Just let them know that you’re representing a US company trying to get a DUNS number but that you’re headquartered in [country outside of the US if that’s an additional consideration].
