Truecaller Guide to the Caller Identification App



In today’s interconnected world, where communication is key, receiving a phone call from an unknown number can be both intriguing and potentially worrisome. Truecaller, a popular caller identification app, aims to alleviate this uncertainty by providing users with a powerful tool to identify and block spam calls, as well as manage their contacts effectively. In this comprehensive guide, we delve into the features, functionality, and controversies surrounding Truecaller.

What is Truecaller?

Truecaller is a caller identification service available as a mobile app for smartphones. It was developed by True Software Scandinavia AB, a Swedish company founded in 2009 by Alan Mamedi and Nami Zarringhalam. Initially launched for Symbian devices, Truecaller expanded its compatibility to other platforms, including Android and iOS, catering to a global audience.

Key Features

  1. Caller Identification: Truecaller’s primary feature is its ability to identify incoming calls from unknown numbers. The app uses a vast database compiled from user-contributed contact information and publicly available sources to display the name or identity associated with a particular phone number.
  2. Spam Call Blocking: One of Truecaller’s most appreciated features is its capability to block spam calls automatically. By analyzing patterns and user reports, Truecaller can identify and filter out unwanted calls, reducing the nuisance of telemarketers, scammers, and other unsolicited callers.
  3. Contact Management: Truecaller serves as a comprehensive contact management tool, allowing users to organize their contacts efficiently. Users can merge duplicate contacts, create custom contact lists, and even backup and sync their contacts across devices.
  4. Call Recording (Premium Feature): Truecaller offers a premium subscription that includes the ability to record phone calls. This feature can be useful for keeping records of important conversations or interviews.
  5. SMS Filtering (Android Only): In addition to call filtering, Truecaller for Android includes SMS filtering capabilities, helping users identify and block unwanted text messages.

Privacy Concerns

While Truecaller provides valuable services, its approach to privacy has raised concerns among some users and privacy advocates. The app collects a significant amount of user data, including contacts, call logs, and even the content of SMS messages. While Truecaller states that this data is used to improve its services and maintain its caller identification database, some users may be uncomfortable with the extent of data collection.

Moreover, Truecaller’s business model relies on sharing user data with third-party advertisers and partners. While users have the option to opt out of this data sharing, the default settings may still raise privacy concerns for some individuals.

Truecaller has faced criticism and controversies over the years, primarily related to privacy issues and its approach to user data. In 2019, the app was accused of violating GDPR regulations by not obtaining explicit consent from users before processing their personal data.

Additionally, there have been instances where Truecaller’s database has been compromised, leading to security breaches and unauthorized access to user information. While Truecaller has taken steps to enhance security measures, these incidents highlight the potential risks associated with relying on third-party services for caller identification.


Truecaller offers a valuable service for users seeking to identify and manage incoming calls effectively. With its extensive caller identification database and spam call blocking capabilities, the app has become a popular choice for smartphone users worldwide. However, concerns regarding privacy and data security persist, prompting users to weigh the benefits against the potential risks when using Truecaller. As with any app, it’s essential for users to understand the implications of sharing their personal data and make informed decisions about the tools they choose to use.
