What is Truecaller?


Truecaller is a popular spam call and text blocking app available for iOS and Android. As of 2024, it boasts over 350 million active users worldwide. Its key features include:

  • Caller ID to identify unknown numbers
  • Spam call & text blocking
  • Crowd-sourced global spam number database
  • Reverse number lookup

Truecaller was founded in 2009 in Stockholm, Sweden. Since then, it has grown to become one of the most widely used apps globally to combat the increasing problem of spam calls and texts. However, it’s not without alternatives and competitors in the call blocking space.

How Does Truecaller Work?

Truecaller uses two primary methods to identify and block potential spam calls and texts:

  1. Phone directory: If you grant permission, Truecaller will use data from your device’s contacts to help identify incoming calls and texts.
  2. Crowdsourcing: When a large number of Truecaller users report a number as spam, that number gets flagged as potential spam for all users.

When an incoming call matches a number in Truecaller’s spam database, you’ll see a color-coded warning identifying it as spam, along with a brief description like “telemarketer” or “suspected scam.”

By keeping its spam database constantly updated through crowdsourcing, Truecaller stays on top of the latest schemes and robocall trends. This allows it to quickly identify and block new spam numbers as they emerge.

Is Truecaller Safe? A Look at Privacy & Security

One common concern is whether an app like Truecaller, which requires access to your contacts and call information, is safe to use from a privacy and security standpoint. Here’s what I found based on my research:

Truecaller is generally considered a safe and legitimate app. It is transparent about the data it collects and how that information is used. Key points regarding Truecaller’s data handling:

  • Personal data collected includes your name, phone number, device information, and any info you add to your Truecaller profile
  • With permission, it will also access your contacts to help identify callers
  • No one can use Truecaller to look up your full name and get your phone number
  • Looking up a number will only show any name and profile info that a user has made public
  • You can manage your data and deactivate your account anytime via the app’s Privacy Center

While Truecaller did face allegations of a data breach in 2019, the company asserted that no sensitive user information was compromised. I found no indication of any major privacy issues since then.

So in summary, while you do have to share some personal info for Truecaller to work, the company seems to handle data responsibly and securely overall. Just be mindful about any sensitive details you choose to add to your public Truecaller profile.
