Attorneys General Urge Phone Companies to Offer Technology that Blocks Unwanted Sales Calls or Texts

Washington, D.C.---The National Association of Attorneys General (NAAG) sent a letter today to the five leading phone companies (AT&T, CenturyLink, Sprint, T-Mobile, and Verizon), urging them to offer call-blocking technology to consumers. Such technology already exists and it would help stop robocalls, scam text messages and unwanted telemarketing calls.

The phone industry previously expressed concern that call-blocking technology may violate federal law. In September 2014, NAAG sent a letter to the Federal Communications Commission (FCC) asking for an official opinion. The FCC responded on June 18, stating the companies could, upon a customer’s request, offer call-blocking technology without violating federal law.

“This clarification by the FCC should remove any doubt about your legal authority to empower consumers by providing call-blocking technology…,” reads the NAAG letter signed by the attorneys general of 44 states plus the District of Columbia. “We urge you to act without delay.”

Today’s letter can be found here.

The National Association of Attorneys General (NAAG),, was founded in 1907 to help attorneys general fulfill the responsibilities of their office and to assist in the delivery of high quality legal services to the states and territorial jurisdictions.
