The Federal Communications Commission approved new rules Thursday to protect consumers from unwanted robocalls, allowing phone companies to proactively block calls that are likely to be fraudulent because they come from certain types of phone numbers. Iowa Attorney General Tom Miller in July had joined a group of 30 state attorneys general in a letter requesting that the agency adopt new rules to address robocalls and spoofed numbers. Unwanted calls, including illegal robocalls, are the top consumer complaint at the FCC, with more than 200,000 received annually. Some private analyses estimate that U.S. consumers received 2.4 billion robocalls per month in 2016. “Iowans call our office every single day to complain about these fraudulent calls they get every day,” Miller said in a release. “Thousands and thousands of Iowans have been scammed out of money because their caller ID display backed up what the caller told them — for example, that the IRS was on the line and they owed money.”
