This is a huge issue with scam/security awareness education. Too many legitimate orgs use the exact behaviors we tell people to avoid. Same thing with email, can't tell someone to never click links in emails when services keep relying on magic links, third-party notification domains, etc. SPF, DKIM, and DMARC do nothing because scammers will just typosquat.
In the phone number example, most of those numbers too are unlisted outbound numbers, you couldn't even google them to verify.
Half the battle is getting legitimate organizations to stop acting like scammers in the first place so that shady behavior becomes an obvious red flag again.

I know this because I had to spend 6 months taking care of my dad while he was dying. We had so many medical people calling us and making appointments, and doing tests, etc etc. And on top of it about 10-15 spam calls a day and it's impossible to differentiate via caller ID. This was all while I was also working full time from home. It's a real hellscape, and these phone scammers are really having a negative effect on people's lives. It made my life miserable at one of the hardest times of my life, and I have nothing but contempt for these fuckers, and no empathy left for the people making the phone calls either. They're all scumbags and deserve time in prison.
