How can I change my Apple email address on my iphone

Hey there ktrobert894,

Thanks for reaching out to the Apple Support Communities.

If you're not signed into your Apple ID account on your iPhone, you'll just want to log out of the Apple ID that is currently signed in, then log back in using your Apple ID.

For steps on how to sign out of the Apple ID on your iPhone, check out this link here: Sign out of iCloud on your iPhone, iPad, iPod touch, Apple TV, or Mac - Apple Support

Sign out on your iPhone, iPad, or iPod touch

1. Go to Settings, then tap your name. 

2. Scroll down to the bottom.

3. Tap Sign Out.

4. Enter your Apple ID password and tap Turn Off. Forgot your Apple ID password? 

5. Turn on the data that you want to keep a copy of on your device.

6. Tap Sign Out.

7. Tap Sign Out again to confirm that you want to sign out of iCloud.

If needed, check out this next resource for help with signing back in: Sign in with your Apple ID - Apple Support

In case the steps above are not what you're looking for, and you're wanting to change the entire email associated with your Apple ID, check out this last resource instead: Change your Apple ID - Apple Support

We hope that's able to help.

Take care!
