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.

telecom operator records, not user submissions.

CNAP is more secure, reliable, and privacy-friendly, as it displays
officially registered caller information directly from telecom networks.
