Germany experiences scams that are common worldwide, including PayPal scams, loved ones scams, and cryptocurrency scams
  • BrazilBrazilians endure an average of 26 spam calls per month, more than double the amount compared to the six countries mentioned above. Banking scams were by far the most common type of phone scam in Brazil in Q3.

Report includes spam rates in US states

For the second quarter in a row, Hiya included US state data in the Global Call Threat Report. The report identifies the top 10 states with the highest spam rates, as well as the 10 states with the least amount of spam.

This quarter, New Hampshire had the highest spam rate of any of the 50 states. Download the report to see which other states made the list. 


Data in the Global Call Threat Report is based on a representative sample of calls observed during Q3 of 2023 on the Hiya Voice Security Network, which includes Samsung Smart Call enabled devices and the Hiya mobile app. 

Spam is defined as unwanted calls, and includes both fraud calls and nuisance calls. The spam flag rate represents calls that Hiya has identified and flagged as either “potential fraud” or “suspected spam.” Spam ratios represent the number of unwanted calls from non-contacts, which are calls placed from numbers that are not in an individual’s local address book.
