Global Community-based Spam Detection
The app works in real-time with over 330 million users. Our community works together to protect each other by marking numbers as spam.
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. 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.
Whether it’s setting up your own call block list, or allowing Truecaller’s auto-block take over, the app will stop unwanted calls in their tracks. With just a switch of a toggle, you can ensure call blocking for all top spammers, or even from numbers that do not belong in your phonebook!
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.
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 have the top spammer list updated automatically to help in auto-blocking top spammers at all times!
