Q&A for How to Remove an Apple ID Phone Number on an iPhone

If you've forgotten both your Apple ID login and the password, the best bet is to go to iForgot online, or take the device to an Apple store where they can help you.

To remove your phone number from iCloud, go to Settings on your iPhone and tap your name at the top to access your Apple ID settings. Select Name, Phone Numbers, Email. Under the "Contactable At" section, tap Edit next to your phone number. You can then remove the phone number by tapping the red minus button next to it. If your phone number is also linked to iMessage or FaceTime, you may need to sign out of these services first or deactivate them by going to Settings > Messages > Send & Receive and Settings > FaceTime.

Make sure you're signed in to your Apple ID on your device. Go to Settings, tap your name at the top, and then tap iCloud. Scroll down and select Find My iPhone to be sure it's disabled. If Find My iPhone is enabled, you'll need to turn it off before you can remove the device. You may be asked to enter your Apple ID password or use your fingerprint/Face ID. If the device still can't be removed, visit Settings, iTunes & App Store, sign out, and try removing it from your Apple ID account by going to appleid.apple.com. If the issue persists, contact Apple Support for assistance.

To change your number, first update your new number with your mobile carrier. On your iPhone, go to Settings, select your name, and update your phone number under "Name, Phone Numbers, and Email." Update any apps and services using your old number in their settings and verify your new number. Inform your contacts of the change, if needed. If you're locked out of services tied to your old number, contact their support with proof of identity to regain access.

To delete an old email address from your Apple ID on your new iPhone, go to Settings and tap your name at the top. Then select Name, Phone Numbers, Email. Under the "Contactable At" section, tap Edit next to the email address you want to remove. Tap the red minus button to delete it. You may need to add a new email address to replace the old one. If you can't remove the email directly, visit the Apple ID website (appleid.apple.com) to manage your Apple ID details and update the email there. If you still have issues, contact Apple Support.

To update your trusted phone number for your Apple ID, go to Settings on your iPhone and tap your name at the top. Then, select Password & Security. Tap Edit next to your trusted phone number. You may need to enter your Apple ID password. From there, you can add your new mobile number as a trusted number. Once added, remove the old number by tapping the red minus button next to it. You may also be asked to verify your new number by entering a code sent to it.
