How to Fetch Caller ID Information Using Python

Caller ID information can provide valuable insights about incoming phone calls, allowing you to identify the caller before answering. We will explore how to fetch caller ID information using Python, a popular programming language known for its simplicity and versatility. By leveraging various APIs and libraries, we can access and retrieve caller information programmatically, enhancing our call management capabilities. Let’s dive into the steps involved in fetching caller ID information using Python.

Fetch Caller ID Information Using Python

Prerequisites: Before we start ,Check you have Python installed on your system. Additionally, you may need to sign up for an account and obtain necessary API credentials for the service provider you’ll be using to fetch caller ID information.

Step 1: Installing Required Libraries: To interact with APIs and retrieve caller ID information, we need to install the required Python libraries. Two popular libraries for this purpose are ‘requests’ and ‘json’. You can install them using the following pip command:

pip install requests json

Step 2: Choosing an API Provider: There are several API providers that offer caller ID lookup services. Choose a provider based on your requirements and sign up for an account. Some popular options include Truecaller, Twilio, Numverify, and OpenCNAM. Obtain the API credentials (API key or access token) provided by your chosen service.

Step 3: Making API Requests: To fetch caller ID information, we need to make HTTP requests to the API endpoint provided by the service. Start by importing the necessary libraries:

import requests
import json

Next, set up the API endpoint URL and include any required parameters, such as the phone number to lookup and your API credentials:

params = {
    "phone_number": "PHONE_NUMBER_TO_LOOKUP",
    "api_key": "YOUR_API_KEY"

Replace “API_ENDPOINT_URL” with the actual API endpoint URL provided by your chosen service, and “PHONE_NUMBER_TO_LOOKUP” with the phone number you want to fetch information for. Similarly, replace “YOUR_API_KEY” with your actual API key or access token.

Step 4: Sending the API Request: Use the ‘requests’ library to send the API request and retrieve the response:

response = requests.get(url, params=params)

This will send a GET request to the API endpoint, including the required parameters.

Step 5: Parsing the Response: The response from the API will typically be in JSON format. Extract the relevant information from the response using the ‘json’ library:

data = json.loads(response.text)

The ‘data’ variable now contains the parsed JSON response.

Step 6: Accessing Caller ID Information: Depending on the API provider, the structure of the JSON response may vary. Refer to the API documentation to understand the structure and extract the caller ID information accordingly. Typically, you can access the caller ID information using the appropriate keys in the ‘data’ dictionary.

Step 7: Handling Errors and Exceptions: When making API requests, it’s important to handle errors and exceptions gracefully. Check the response status code to ensure the request was successful and handle any potential errors or exceptions that may occur during the API call.


By these steps, you can fetch caller ID information using Python and enhance your call management capabilities. Utilizing APIs and libraries, Python enables you to automate the retrieval of caller information and integrate it into your applications or services. Whether for personal use or business purposes, fetching caller ID information programmatically empowers you with valuable insights into incoming calls. Explore different API providers, experiment with the retrieved data, and discover new ways to leverage caller ID information within your projects.
