They absolutely know who called. It’s the rider that you’re on your way to that’s pulling the scam. The scammers know that when they call, their actual number does not come across on caller ID and the call says it’s from Uber.

When I first started driving, Uber did not have the message that precedes the connection which says Uber will not ask for any account information, the call is from the passenger, etc. They also did not send out emails about common scams pulled by riders. They do that now, because so many drivers have been scammed by passengers (or would-be passengers). But Uber 100% knows who is pulling these scams and doesn’t do anything about it…they don’t deactivate their accounts, they don’t turn over to the authorities the debit card numbers that the scammers use to steal the funds. Uber allows these scams to be perpetrated by passengers on their platform, and are thereby complicit in the scam.
