Attorney General Alan Wilson pushes federal government to strengthen “Know Your Customer” rules in effort to combat illegal robocalls

(COLUMBIA, S.C.) - Attorney General Alan Wilson and a bipartisan coalition of 49 other attorneys general are pushing the Federal Communications Commission (FCC) to strengthen its “Know Your Customer” (KYC) rules to help prevent scammers from using the U.S. communications network to make illegal robocalls. KYC rules require phone companies to know who is making calls through their networks and what kinds of business these customers are conducting. With that information, phone companies can suspend or terminate callers who use their networks to make unlawful calls or decline to do business with customers that aren’t legitimate companies or can’t prove that they conduct lawful business.  

“Robocalls drive us all crazy, so attorneys general are united in trying to fight them,” Attorney General Wilson said. “But we need federal government action to be able to make a dent in these calls, and that’s why we’re urging the FCC to strengthen its rules.”

Illegal robocalls start with an originating voice service provider allowing bad actors to use its network. If scammers can’t get their calls onto the U.S. communications network, they can’t make illegal robocalls. So, these originating voice service providers are key to stopping these calls from reaching people. Attorney General Wilson has previously asked the FCC to strengthen its KYC rules.

Even though providers are already required to know who their customers are, the current requirements aren’t strong enough—as evidenced by the prevalence of robocall scams. Last year, Americans received more than 29.6 billion scam robocalls and texts and lost nearly $2 billion to these scams. 

In addition to what the FCC is already doing, attorneys general urge the FCC to:  

• Require providers to understand their customers’ business. In addition to verifying a customer’s identity and existence, originating providers should also be required to examine and understand the customer’s business practices, reputation, history, intended use of services, and their compliance with state and federal laws.
• Hold all originating providers to KYC standards. Even small originating service providers should be required to meet enhanced KYC standards. Scammers use originating providers, regardless of size, to access the communications network. In fact, illegal calls are often facilitated by smaller voice service providers. Not holding small providers to the same standards could cause them to be even more attractive to bad actors looking to use them to make illegal robocalls.
• Require originating providers to collect additional information on high-risk customers. While KYC requirements should be universal, the attorneys general support additional, long-term monitoring of customers who are more likely to make illegal robocalls, such as those subscribing to high-volume services.  

This letter comes after a coalition of 49 attorneys general sent reply comments to the FCC earlier in July, encouraging it to crack down on illegal robocalls by strengthening rules that would cut off scammers’ access to legitimate phone numbers.

The two letters are part of Phase 2 of Operation Robocall Roundup, an effort by the Anti-Robocall Multistate Litigation Task Force to crack down on robocalls across the country. Phase 1 launched in August 2025 with warning letters sent to 37 smaller voice providers that were allowing suspected illegal robocalls onto the U.S. telephone network. Phase 2 launched in December and expanded the crackdown to four of the largest intermediate voice service providers in the country. 

Attorney General Wilson is joined in signing the letter by the attorneys general of Alabama, Alaska, American Samoa, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, District of Columbia, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, Tennessee, U.S. Virgin Islands, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.
