Note: If you are using a version of truecallerjs that is older than 1.1.2, we recommend referring to the truecallerjs-v1.1.2 documentation for instructions. Note: If you are using truecallerjs version from 1.1.3 to 1.1.5, please refer to the truecallerjs-v1.1.5 documentation for instructions.

Command Line Usage

To use TruecallerJS from the command line, you can run the truecallerjs command followed by the desired options and arguments.

Here are some examples of the available options:

  • truecallerjs login: Use this command to log in to your Truecaller account.

  • truecallerjs -s [number]: Use this command to search for a phone number and retrieve the caller name and related information.

  • truecallerjs --bulksearch, --bs command is used to performing bulk number searches using the Truecaller service. It allows you to search for multiple phone numbers at once, making it convenient for processing large sets of phone numbers in a single request.

  • truecallerjs --bulksearch, --bs: Use this command to perform a bulk number search.

  • Additional options include --raw, --name, --email, --json, --xml, --yaml, --text, --nc, --installationid, --verbose, and --help.

For example:

~$ truecallerjs -s +9199123456789 --json
     "name":"Sumith Emmadi"

~$ truecallerjs -s +9199123456789 --name
Name : Sumith Emmadi

Example for bulk search

truecallerjs --bulksearch <phone_number_1>,<phone_number_2>,<phone_number_3>,...,<phone_number_n>

Replace <phone_number_1>, <phone_number_2>, ..., <phone_number_n> with the actual phone numbers you want to search. Separate each phone number with a comma.

 ~$ truecallerjs --bs 9912345678,+14051234567,+919987654321

Note : If the country code is not specified for a phone number, it will default to using your own country code.


Please note the following limitations when using the --bulksearch option:

  1. Maximum Number of Phone Numbers: The tool supports searching 30 or fewer phone numbers at once in a single request. If you exceed this limit, you may need to split your input into multiple requests.

  2. Formatting: Ensure that the phone numbers are correctly formatted and do not contain any additional characters or spaces. The tool expects the phone numbers to be provided in a comma-separated format.


To use the project, start by installing the truecallerjs package via npm:

npm install truecallerjs

Simple Example

Here's a basic example of how to perform a normal search for a phone number:

import truecallerjs, { SearchData, Format } from "truecallerjs";

async function performTruecallerSearch(): Promise<void> {
  const searchData: SearchData = {
    number: "9912345678",
    countryCode: "IN",
    installationId: "a1k07--Vgdfyvv_rftf5uuudhuhnkljyvvtfftjuhbuijbhug",

  try {
    const response: Format = await;

    // Additional response methods:
    // console.log(response.xml());
    // console.log(response.yaml());
    // console.log(response.text());

    // Example of available data from the response:
    console.log(response.getName()); // "Sumith Emmadi"
    console.log(response.getAlternateName()); // "sumith"
    console.log(response.getAddresses()); // {....}
    console.log(response.getEmailId()); //
    console.log(response.getCountryDetails()); // {...}
  } catch (error) {
    console.error("Error occurred:", error);


In the above example, the truecallerjs package is used to search for a phone number. The search_data object contains the necessary parameters, including the number, country code, and installation ID. The response from the function provides various methods to access the returned data.

Note : Make sure to log in using the truecallerjs login command and obtain your installation ID using the truecallerjs -i command.

Bulk Search on Multiple Phone Numbers

The truecallerjs package also supports bulk search on multiple phone numbers:

import truecallerjs, { BulkSearchData, Format } from "truecallerjs";

async function performBulkTruecallerSearch(): Promise<void> {
  const countryCode: string = "IN";
  const installationId: string = "a1k07--Vgdfyvv_rftf5uuudhuhnkljyvvtfftjuhbuijbhug";
  const phoneNumbers: string = "+9912345678,+14051234567,+919987654321";

  try {
    const response: BulkSearchData = await truecallerjs.bulkSearch(phoneNumbers, countryCode, installationId);
  } catch (error) {
    console.error("Error occurred:", error);


In this example, the truecallerjs.bulkSearch() function is used to perform bulk searches on multiple phone numbers. The phoneNumbers parameter should contain the phone numbers separated by commas. The countryCode and installationId parameters are used to specify the default country code and installation ID, respectively.

Note : Make sure to log in using the truecallerjs login command and obtain your installation ID using the truecallerjs -i command.

For more details and additional functionalities, please refer to the documentation, including the process for logging in and obtaining the installation ID.
