A free online app, Reported.tel, analyzed over one million Federal Trade Commission complaints during the summer of 2019 to see which states are most affected by robocalls.

The FTC publishes a list of consumer complaints every weekday, which includes phone number, city, state and type of call for US-based phone numbers.

Reported.tel found that residents of Alaska, Indiana and North Dakota received the least amount of unsolicited calls, with North Dakota having the least events per capita.
