Caller ID says Maybe

If it is a phone call and you do not have the person in your Contacts the Caller ID display comes from the other persons phone/cell service provider. Facebook, emails, LinkedIn, Apple ID, Instagram, TikTok, etc. are not involved. If the caller is using a paid service for spoofing the display can be anything.

I did answer your question.

That may be a spoof Caller ID display by the person calling you. It is not a privacy breach.

You may have had the caller name on the contact list previously and now it no longer exists in the Contacts App. Please add it to the Contacts app and then the "Maybe" will not appear.
