Question 1

Will my request quota be deducted if the API experiences a server error or downtime?

Accepted Answer

No, your request quota will not be deducted if our server experiences an internal error, downtime, or system disruption (e.g., 5xx server errors). Additionally, your quota will not be deducted if the phone number's country or mobile carrier (provider) cannot be identified or found.

However, please note that if the API request is processed successfully by the server and returns a "Phone Number Not Found" result, it counts as a valid lookup and will be deducted from your quota.

Question 2

What phone number format is required, and does this API support international numbers?

Accepted Answer

Yes, this API supports phone number lookups for all countries worldwide. To ensure accurate results, please input the phone number in international format including the country calling code (for example, 08123456xxx or 628123456xxx for Indonesia) or specify the corresponding country code parameter in your request.

Question 3

Is this an official Truecaller API, and how accurate is the returned information?

Accepted Answer

No, this is an unofficial third-party API hosted on JoJ API and is not affiliated with Truecaller. The data retrieved—such as caller name, carrier, and spam score—depends entirely on public availability and community-sourced records. While highly effective for verification, it does not guarantee 100% protection against phone spoofing or fraud.
