About us.

Truecaller is a Swedish company founded in 2009 in Stockholm, Sweden by Nami Zarringhalam and Alan Mamedi. The app began when our co-founders were just students who wanted to create a service that would easily identify incoming calls from unknown numbers.

Today, Truecaller is loved by over 330 million monthly active users around the world, and is the go-to app for Caller ID and spam blocking.

Why we exist.

Remember the days when the phone rang and you didn’t know who it was? Back then, we felt a need to know who contacted you, as well as those you wanted to avoid. Truecaller was born out of this. To remove uncertainty. To separate signal from noise.

We can gladly say those days of uncertainty are over with Truecaller. We are committed to build that trust everywhere by making tomorrow's communication safer, smarter and more efficient. No matter if it’s in the beginning of a call, in the middle of a transaction or at the end of a signature.
