Worth noting that if you're a "single person business", you don't need to bother with a DUNS number: https://developer.apple.com/support/ios/D-U-N-S.html

(ie: If you were planning on hacking something together and charging for it on the App Store, go for it. This won't affect you.)

Ah... I was wondering how I'd gotten around this when I signed up as a dev.

I think this is a recent-ish thing. I didn't have to go through it when creating a company account > 18 months ago.

I'm not sure what problem Apple were trying to fix.

It's probably just a hoop they make you jump through to make sure you're "serious" so that they can cut down on app approval times without hiring a bunch more reviewers.

Definitely seems to be recent. I signed up my company back in July and had to fax in identification forms. No DUNS required.
