Region change
I need to download an app in a different region, Germany. Can I change regions, download the app, and change my region back without having to set up a new Apple ID account?
Question marked as
Not easily. For example, do you have a credit card billed to you at an address in Germany?*
This article describes how to change your country setting and the requirements and results of doing this:

"Make sure that the billing address for your payment method matches the billing address for your Apple ID. In some cases, you might need to call your bank or financial institution to authorize international or online purchases. You might also need to confirm that the mobile number associated with your payment method is correct."
