Truecaller's core function is its caller ID feature. When you receive a call from an unknown number, the app uses its vast database to identify the caller. This database is built primarily through "crowdsourcing," which means it relies on data provided by its users.
When a user installs the app, they give it permission to access their contacts, which are then uploaded (anonymized and not made public) to the Truecaller server. This collective information creates a massive directory of phone numbers and names.
The app also uses community feedback to identify and block spam, scams, and fraudulent numbers. When a number is reported as spam by a certain number of users, it is flagged in the database and shown as "Spam" on the caller ID.
Key Features and Services
