Will the eShop downloads be deleted if I delete the Nintendo Network ID

I decided to test it. My usual profile settings are USA with no state set. Here are my results after changing my location (called 'Region' in the profile settings, which is confusing) to Argentina - Buenos Aires.

• I was still able to play downloaded titles. Shovel Knight worked fine, but I had to accept a basic terms of use agreement.
• I could not enter the eShop or Pokemon Bank, and they displayed a message saying that the region (location) had been changed, and that it had to be changed back to access those services.
• After changing my region back, I had to accept a terms of use agreement for downloaded Pokemon Bank, but not for Shovel Knight (Shrug)
• I was able to connect to any NNID services as though nothing had happened.
• The only thing I didn't try was creating a new NNID. I wasn't sure if I would have to delete the one I have now, but I know for certain that if you delete one you WILL lose all downloaded titles permanently.

Verdict: As long as you don't delete your NNID, you can change your location settings as much as you like, and you won't lose your downloaded titles, although you may not be able to use anything that requires your NNID to be logged in from your original location.

According to the official help page from Nintendo, you can't change the information that you want to change (your country information).

The Nintendo Network ID (username) and country cannot be changed once the account is created. The only way to change this information is to create a new Nintendo Network ID.

You do not need to delete the current Nintendo Network ID to create a new one on your system. Deleting a Nintendo Network ID will also delete any purchases or digital content that is associated to that account.

Nintendo 3DS family systems can only support one Nintendo Network ID at a time. However, you can format the system to deactivate the current NNID and create a new one. (The existing account and purchases will not be deleted, and can still be re-linked to the same system in the future.)

The only things that you can change without making another NNID are gender, region, time zone, and e-mail address. The country and birthday aren't able to be changed.
