DETROIT -The U.S. dropped in the ranking of most spammed countries from second in 2020 to twentieth in 2021, largely due to the increase of spam call volumes in other countries. In fact, Vietnam more than tripled its volume from January to October of this year, and Indonesia doubled in the same period.

Despite this ranking within a global context, total spam call volumes received by Truecaller users in the U.S. have remained fairly consistent from January to October 2021. Volumes fluctuated slightly from 3,016,550 spam calls in January, to 2,970,134 in April, to 2,849,676 in July, and back up to 3,115,861 in October. These numbers showcase that spammers are becoming more sophisticated, and consumers are facing higher spam call volumes as a result.

Additionally, according to Statista, there are over 294 million smartphone users in America. Truecaller users in the U.S. receive an average of 4.8 spam calls per month, and extrapolating the figure based on this data equates to a staggering 1.4 billion spam calls per month.

Key trends from other parts of the world

  • Over 202 million spam calls were made by just one spammer in India. That’s over 664,000 people that were disturbed by spam calls every day and 27,000 people every hour – from just one phone number.
  • Brazil has retained its title of the most spammed country in the world (four years in a row) with 32.9 spam calls per user per month. There is a significant gap between the average number of spam calls received in Brazil (32.9 calls per user per month) versus Peru (18.02 calls per user per month), which stands in the second position.
  • The rankings look very different when comparing the average number of incoming spam calls, vs. SMS messages per user per month. Cameroon tops the list, followed by Somalia, Tanzania, Congo, Burkina Faso, Ivory Coast, Benin, and more. SMS spam is largely affecting users across the African continent.
  • South Africa was typically one of the most spammed countries in the world: fifth in 2017, fourth in 2018 and sixth in 2019. It dropped sharply to seventeenth place in 2020 and has again jumped back up to ninth place this year.
  • In the top 20 countries – Brazil is in a class of its own. The next 10 countries in the list are comparable in terms of number of spam calls received. And the last nine are in a group of their own, between 4.5 to 6.7 spam calls per user per month.
