If you need an Apple ID that’s an email address
The Apple ID you use to set up your Apple ID account must be an email address, such as kristina.lucas77@icloud.com. If your Apple ID isn’t an email address, you can change it by signing in to your Apple ID account page.
Note: In several countries and regions, you can use a phone number instead of an email address as your Apple ID. See the Apple Support article Use your mobile phone number as your Apple ID.
