Mine literally come from the verified coinbase phone number and say coinbase and everything. If I didn't know for sure they are not calling me I'd think it was real 100%.
I'm very interested in knowing the actual current state of affairs WRT spoofing and a lot of people make claims without evidence which makes it hard to find out. I thank you for providing your evidence here because it does sound like some carriers are still not enforcing. Which is obviously a problem.
I think it’s a mix. If the CID has someone’s name, then it’s almost certainly spoofed, but sometimes, it just has a town name, and that might be what you mean.
There was this telco, in Upstate New York, that was infamous for being a firehose of scam/spam robocalls. I think they may have been shut down, though, because I haven’t seen their numbers in the CID for a couple of years.
I would suggest that carriers are limited in what they can do. Crooks be crooks, and many of them are very clever. They usually figure out how to weasel past the guard dogs.
Not my job to "verify," in the technical sense.
When a call for an Indian crypto pump comes in as "SMITH, ROBERT", and a local exchange, I call that "spoofed."
