Spam Blocking

Spam blocking has never been easier with Truecaller! The app automatically identifies robocalls, telemarketers, scams, fraud, harassment and more!

The app runs in the background on your Android, therefore, working to identify your incoming calls or SMS to detect if it’s a known spammer.

37.8 billion
Spam Calls Blocked and Identified
182 billion
Spam Messages Blocked


The app works in real-time with over 300 million users marking numbers as spam. This means that if someone marks a number as spam in the U.S., another person who receives a call from that number, say, in Germany, will see it’s marked as spam. Our community works together to protect each other.

Global spam detection

You’re not just protected from domestic spammers. Our international database of spammers, which are reported by our users, is available for anyone who uses Truecaller to help reduce noise from unwanted numbers.

Spam Statistics

Don’t just block spammers, learn more about their calling patterns! Our unique spam insights will tell you what time a particular spammer is active, how many calls they’ve made recently, and their spam markings.

Spam Identification

Create your own block list inside the app, or let our Caller ID automatically detect top spammers who have been heavily marked by our community. The Caller ID will flash red, and you will be able to see their name, location, and spam markings. Our Premium users will also be able to auto-block top spammers.
