Where does my email verification code go when using an Apple private email?

If you signed up using Continue with Apple, Apple is routing your email verification code to one of your Apple ID’s verified email addresses.

To view these email addresses:

1. Open the Settings app on your iPhone
2. Tap your name at the top
3. Tap "Name, Phone Numbers, Email." Here, your Apple ID (primary email address) will be listed under "Contactable At."
   

Your verification code will be in the inbox listed as your primary email address in this screen. If it doesn’t appear in this inbox, please check your spam folder.
