This is what STIR/SHAKEN is supposed to do. Your phone and carrier in the US probably support it, but it’s not obvious. On iPhones there will be a little check mark under the number for inbound calls on your recent call list. This doesn’t carry over to things like voicemail however - where the check isn’t shown.

This model also doesn’t work for businesses that route all outgoing calls through one number, as that is essentially caller ID spoofing.

I'm neither from the US, nor an iOS user, I don't think I ever saw a checkmark when recieving a call.

The Google dialer does ask me whether unknown callers were businesses and try to ID businesses that enough people report
