- Tap the Settings icon.
- Tap your name, which appears near the top of your screen (it should say Apple ID under your name).
- Choose Name, Phone Numbers, Email.
- Where it says Reachable At, click the blue Edit button.
- A red minus sign appears next to your Apple ID. Tap the red minus.
- A screen will pop up where you can choose Cancel or Continue. Choose Continue.
- You'll get a screen where you can enter an email address. This email address will become your new Apple ID.
- Look for a confirmation email at the new email address. You'll need to verify the email to complete the change in your Apple ID.
Note, if you change your Apple ID to an Apple email address (@icloud.com, @me.com, or @mac.com), you won't be able to change it back to a third-party email address in the future, according to Apple. The third-party email address you used before will appear on your Apple ID account as an additional email.
While you are editing your Apple ID, you can also add or remove phone numbers or email addresses from your account.
