How to Delete Your Apple ID permanently
This is a guide on how to delete an Apple ID in the most complete manner that is humanly possible. We all know that associating data with an account that is related to the web might leave some residual data at some point in time, even after supposed deletion. Fortunately, Apple will gladly comply with your removal request and fully delete an account.
Deleting your Apple ID through Apple Support
As of now, there is no official, recommended route. But: We can use a privacy contact form that Apple provides on its website. Simply follow the below link and select “I have a question about Privacy issues” to get to the right form.
Fill in your Region, First and Last name, Email, Subject field and use the Comment field to explain that you would like to have your Apple ID deleted. Of course, to make things easier on the customer support representative dealing with your case, you should provide Apple with the Apple ID in question.

Apple will typically ask you to confirm this request, keep an eye on your email inbox for further instructions.
Deleting individual data items from your Apple ID

Open up iTunes on your Mac or PC and click your name, then select Account Info from the menu. On the following page, select “Edit” next to the corresponding item you would like to change.
on iPhone / iPad:
Go to your Settings App, then scroll until you see “iTunes & App Store”. Tap your Apple ID, then tap “View Apple ID”. From here, you can tap your Payment Information and choose to edit or remove it. This is a quick and easy way to disconnect a credit card or other means of payment from your Apple ID.
