Last Updated : 23 Jul, 2025

Prerequisite : 

• Beautiful soup
• Requests module

In this article, we are going to see how we get Caller Id information using numverify API. Numverify offers a powerful tool to deliver phone number validation and information lookup in portable JSON format by Just making a request using a simple URL.

For the following program to work you must have an API key and to get one simply Click here.

Module needed:

• bs4: Beautiful Soup(bs4) is a Python library for pulling data out of HTML and XML files. This module does not come built-in with Python. To install, type the following command in your terminal.

pip install bs4

• requests: Request allows you to send HTTP/1.1 requests extremely easily. This module also does not come built-in with Python. To install, type the following command in your terminal.

pip install requests

Approach:

• Import module
• Make a function for GET request
• Pass the URL with existing API key, mobile number, and country code
• Now retrieve the caller id information

Program:

# import module
import requests
import pandas as pd 
from bs4 import BeautifulSoup

# link for extract html data
# Making a GET request 
    
def getdata(url):
    r=requests.get(url)
    return r.text
# API key
# Enter your own API key instead of 'YOUR API KEY'
api = 'YOUR API KEY'

# number and country code
number = '9852638787'
country = 'IN'

# pass Your API, number and country code
# in getdata function
htmldata=getdata('http://apilayer.net/api/validate?access_key='+api+'&number='+number+'&country_code='+country+'&format=1')
soup = BeautifulSoup(htmldata, 'html.parser')
