When you make FaceTime calls on iPhone and iPad, recipients see your caller ID—an email or phone number. If that caller ID isn’t what they expect, they won’t know who’s calling. Here’s how to change your caller ID.
When you call someone using FaceTime, your caller ID is the email or phone number that appears on their screen. If you have many email addresses associated with your Apple ID, then there’s even more chance that you’re calling people with one they don’t recognize. That could lead to calls going unanswered, or an unexpected email address being shared with someone you don’t want to have it.
Changing the caller ID that is used when you initiate a new FaceTime call is a relatively simple process, and here’s how to go about doing it.
To start, open the Settings app and tap “FaceTime.”
Note that email addresses will only appear if you are signed in with your Apple ID, so make sure you’re signed in and tap the “Use your Apple ID for FaceTime” button if not.
Next, tap the number or email address you want to use as your caller ID under the “Caller ID” section.
