Political robocalls are exempt from the United States National Do Not Call Registry.[25][26] The Telephone Consumer Protection Act of 1991 (TCPA) and Federal Communications Commission (FCC) regulations prohibit anyone (including charities, politicians and political parties) from making robocalls to cell phone numbers without the recipients' prior consent.[27] The FCC permits non-commercial robocalls to most residential (non-cellular) telephone lines.[28]
