The service is a global telephone directory that has caller ID, social media integration and call-blocking functionality. It uses crowdsourced data, which enables it to work even in countries such as the UK and India where public data is not available. When a user registers for Truecaller, names and numbers from their contact list are uploaded to the service's servers for other users to look up.

Truecaller is available for Android,[8] iOS,[9] BlackBerry, Symbian,[10] Windows Mobile,[11] Windows Phone 7, and Windows Phone 8. The app is available in all countries.[12][13]
