How do celebrities and prominent politicians authenticate themselves when calling someone?

I’m with HeyHomie. I do not have caller ID. If I received a call from someone identifying themselves as a former President, random celibrity, or the sheriff I would accept it is them. Why not? I’m not a local mover or shaker, rich, or in any other way a notable. Even if they are complete fakes, I have nothing to lose.

You folks out then that won’t pick up the phone unless you know the caller personally are missing out on those occasional calls that might be useful to you or them. I’m constantly baffled by how disinterested those with multiple communication tools refuse to use them. I have a landline. I answer the phone if it rings and I’m not too busy to answer.
