“My office is aggressively fighting illegal robocalls and texts, but we need stronger federal rules to stem the flow of calls at the source. Federal Know Your Customer requirements have been useful, but until now, they have lacked effective enforcement mechanisms,” said Attorney General Lynn Fitch. KYC rules require phone companies to know who is making calls through their networks and what kinds of business these customers are conducting. If scammers can’t get their calls onto the U.S. communications network, they can’t make illegal robocalls. Scammers use originating providers, regardless of size, to access the communications network.
