How do I change my billing address

Hello,

I see you have listed a Mac computer as your equipment so I am assuming you wish to do this on your Mac. Note that earlier instructions talk about doing this in iTunes but iTunes hasn't been on Mac computers for several years now.

See the support document "Add a payment method to your Apple ID" by clicking on this link -->

Add a payment method to your Apple ID - Apple Support

Proceed to the section about doing this on a Mac.

1. Open the App Store.
2. Click your name. If your name doesn't appear, click the Sign In button, sign in with your Apple ID, then click your name.
3. Click Account Settings.
4. Next to Payment Information, click Manage Payments. (If you're using an older version of macOS, click Edit next to Payment Type.)

One at the point where you would enter the address information you should be able to edit it instead.

1.

Sign in to your Apple ID account page and edit / update your Apple ID details.

2. 

To change the billing address you can do (macOS & Windows OS) via iTunes
