Q: How can i zero my blance and change my rigon..

Hi, Mansor1234578.  

Thank you for visiting Apple Support Communities.  

I understand that you need to change your Apple ID region.  You can either make a purchase to bring your balance to zero or check out the attached information below.  

Store credit balance

You must spend your balance before you can change stores.

If your store credit is less than the cost of a single item on the iTunes Store, App Store, iBooks Store, or Mac App Store, you can add a credit card to your account. When you buy an item, you will use the remaining store credit and charge the remainder of the purchase to your credit card.

If you don't have a credit card, contact iTunes Store support.

Can't change the country of your iTunes Store, App Store, iBooks Store, or Mac App Store account
