NNID question

I know I insist that the NNID must have credit cards...guess I'm wrong,as the funds can catch up later on,because I dug some free titles in the E-shop recently,now the question is...does registering for a NNID means I can't change regions when I'm not logged in? as of now(hopefully won't be a major issue for me personally) I'm stuck with the "US-only" and is it possible for another account that doesn't have something to do with USD?(it pissed me off because it's too expensive as it's about to approach 15,000 IDR..cripes)

my 3DS XL is only compatible with ESRB rated titles,I don't bother using my brother's Australian 3DS XL,because it's his,not mine.

ok.......my body is ready for NNID.

update: NNID is a go for me(finally I have the power in my "distance")

Nice, congrats on getting your NNID.

This is the first time I've ever heard it referred to as NNID...

@drewgamer58: NNID is short for Nintendo Network ID,never heard of one?,perhaps you never own either a 3DS or a WiiU(the latter is what I don't have until now)

@Smashbrossive50: no, I have the New 3DS and a Nintendo ID, I've just never heard it as "NNID".

@drewgamer58: it's easier said it short rather than extend it,at least it's the same thing,it's shortened because of context preference,that's being informal if you must understand it.
