Truecaller is a widely recognized call identification and spam-blocking app that helps users identify unknown callers and filter out unwanted calls. WhatsApp, on the other hand, is one of the most popular messaging platforms, known for its end-to-end encryption and seamless communication features. Many users wonder whether Truecaller works with WhatsApp, especially when it comes to identifying unknown WhatsApp callers.
How Truecaller Integrates with WhatsApp
Truecaller has introduced features that allow users to identify spam calls even on platforms like WhatsApp. When an unknown number calls via WhatsApp, Truecaller can attempt to provide caller details based on its extensive database. However, the level of success depends on various factors.
The integration is not as direct as it is with traditional phone calls. Instead of Truecaller automatically displaying caller information within WhatsApp, users often need to manually copy the unknown number and paste it into Truecaller for identification.

Key Features of Truecaller with WhatsApp
Below are some of the important ways in which Truecaller can be useful for WhatsApp users:
- Spam Detection: Truecaller maintains a vast database of spam numbers, which helps identify potential scam or telemarketing calls coming from WhatsApp.
- Manual Number Lookup: If you receive a WhatsApp call from an unknown number, you can copy the number and check Truecaller for details.
- Community-Based Updates: Truecaller relies on user reports to mark numbers as spam, meaning its effectiveness improves as more users contribute.
Limitations of Using Truecaller with WhatsApp
Despite its usefulness, Truecaller does have some limitations when it comes to WhatsApp calls:
- Limited Automatic Detection: Unlike regular calls, Truecaller does not always automatically display information for WhatsApp calls.
- Dependence on Database Updates: If a number is not widely reported or listed in Truecaller’s database, it may remain unidentified.
- Privacy and Data Concerns: Truecaller collects and stores contact information, which raises privacy concerns for some users.
How to Use Truecaller for WhatsApp Calls
Since Truecaller does not integrate natively with WhatsApp, users must follow a few steps to identify unknown WhatsApp callers:
- When you receive a WhatsApp call from an unknown number, take note of the number.
- Copy the number from WhatsApp and open the Truecaller app.
- Paste the number into Truecaller’s search bar and look up the contact details.
- If the number is spam, Truecaller will indicate its spam score based on user reports.

Privacy Considerations
Users should also be aware of the privacy implications of using Truecaller. The app collects data from users’ contact lists to enhance its database, which might lead to concerns about personal information being shared. While Truecaller has stated that it does not store WhatsApp call details, users should remain cautious and review the app’s privacy policies before using it extensively.
Conclusion: Does Truecaller Work with WhatsApp?
Truecaller can be a helpful tool for identifying unknown WhatsApp callers, but it does not offer full or direct integration with WhatsApp’s calling feature. While it allows manual number searches and provides spam warnings, users cannot rely on it for immediate caller identification within WhatsApp itself.
For those who frequently receive calls from unknown numbers on WhatsApp, using Truecaller alongside WhatsApp can enhance security and help avoid potential scams. However, users should also consider privacy aspects and alternative methods for verifying unknown contacts to ensure a safe communication experience.
