CNAP vs Truecaller – Key Differences

Kokila Chokkanathan
Both CNAP and Truecaller help identify unknown callers, but they work in very different ways.

1. What is CNAP?

CNAP (Caller Name Presentation) is a telecom-regulated system that shows the official registered name of the caller on your phone.

Works directly through your mobile network, not via a third-party app.

Goal: Reduce spam, fraud, and misrepresentation in calls.

2. What is Truecaller?

Truecaller is a third-party app that identifies callers based on a user-generated database.

It shows names or tags even for unknown numbers.

Relies on data collected from users’ contacts and reports.

4. Why CNAP Is Considered Better

Reduces Fraud: Harder for fraudsters to spoof caller ID compared to third-party apps.

5. Limitations of CNAP

Only shows the registered name of the number owner.

May not indicate spam or user-reported categories like Truecaller does.

Bottom Line: While Truecaller helps identify spam and unknown callers using crowdsourced data, CNAP is more secure, reliable, and privacy-friendly, as it displays officially registered caller information directly from telecom networks.
