What does unknown caller mean on iphone?

Got a call that showed as Unknown Caller rather than No Caller ID. Is there a difference between the two? Wondering if it's a scam or just a withheld business line.

The caller hid their number on their end, so your phone has nothing to show. Could be a withheld personal number, an office line, or a scam call. If they're getting annoying, Settings > Phone > Silence Unknown Callers sends anything not in your contacts to voicemail. Just remember it'll catch delivery drivers and doctor's surgeries too.
