Introduction

Phone number validation and lookup are critical in various applications, from user registration to fraud prevention. By validating phone numbers, developers ensure data accuracy and enhance the user experience. In this article, we will create a Python-based solution to validate and retrieve details of global phone numbers using the numverify JSON API.

Prerequisites

Before diving into the implementation, ensure you have the following:

1. Python Installed: Install Python 3.7 or higher.
2. numverify API Key: Sign up at numverify and obtain your API key.
3. Requests Library: Install the requests library.

The Script

Below is the Python script to validate and retrieve phone number details:

import requests
def validate_phone_number(phone_number, access_key):
    """
    Validate and look up a phone number using the numverify API.
    :param phone_number: The phone number to validate (including country code).
    :param access_key: Your API access key.
    :return: A dictionary with…
