How Truecaller app decides which name to display among many?

When multiple people save the same phone number with different names in their contacts, Truecaller's caller identification algorithm takes several factors into account to decide which name to display when that number calls a Truecaller user:

1. **User Contribution**: Truecaller relies heavily on crowdsourced data, which means that user contributions play a significant role in determining the caller's name. If a large number of users have saved a particular name for a specific phone number, that name is more likely to be displayed for other Truecaller users when they receive a call from that number.

2. **Contact Frequency**: Truecaller considers the frequency with which a specific name is associated with the phone number in the contacts of its users. If a particular name appears more frequently than others, it is given higher priority for display.

3. **Contact Details**: Truecaller may prioritize names that have additional details, such as a profile picture, address, or other information, as these entries tend to be more comprehensive and credible.

4. **User Interaction**: Truecaller also takes into account user interactions and feedback. If a user frequently interacts with a contact or tags a specific name for a particular phone number, it can influence the caller ID display for that number.

5. **Data Confidence and Consistency**: Truecaller uses various data sources to build its database. The algorithm assesses the confidence and consistency of the data before displaying a name. If multiple sources have consistent information, it is more likely to be displayed.

6. **Personal Contacts**: If a Truecaller user has a specific contact saved with a name in their personal address book, Truecaller may prioritize that name over other user-contributed names.

7. **Local Language and Region**: Truecaller considers the local language and regional preferences when displaying caller names, especially if the caller ID information is provided in multiple languages.

8. **Relevance to User**: The algorithm may also consider the relevance of the name to the user based on their geographical location, social connections, and other factors.

It's important to note that Truecaller's caller identification system continuously learns and improves over time based on user behavior, feedback, and data contributions. As a result, the accuracy and relevance of the displayed names may vary depending on the information available in the Truecaller database and user-contributed data.
