How to Find Phone Carrier in Python

by | Aug 18, 2023

Precise details about phone carriers are essential in many functionalities, such as enhancing user satisfaction and enhancing security measures. This guide will examine two ways to find phone carrier information utilizing Python. We’ll go over both API-based solutions and regular expression methods, giving you the freedom to choose the most suitable approach to achieve the mobile carrier lookup functionality. When you finish reading this guide, you will have the ability to incorporate carrier information retrieval into your applications with ease. This will guarantee precise data verification and a better user experience.

What are the Prerequisites?

Make sure you have the necessary requirements before we explore the complexities of utilizing Python to locate a phone carrier.

A basic understanding of Python programming

Although this guide will walk you through the required procedures, having a basic understanding of Python programming concepts would be advantageous. This involves being able to comprehend variables, functions, and fundamental control structures.

A functional Python environment (preferably Python 3. x)

To execute the code examples given in this guide, it is necessary to have a working Python environment. If you do not have Python installed on your computer, you can download and install it from the official Python website. It is advisable to use Python 3. x for better compatibility.

Basic terminal or command prompt usage

It is important to have proficiency in using the terminal or command prompt to execute commands. This involves tasks such as installing packages through pip, a package manager and executing Python scripts.

What are the Methods Used to Find Phone Carriers in Python?

There are 2 methods for finding phone carriers using Python. They are explained in detail in the section below.

Method 1: Using Carrier Lookup APIs

If you’re looking for a dependable and advanced method to identify phone carrier information, then Carrier Lookup APIs are the way to go. These APIs connect with substantial databases that contain information about phone numbers, making it easy to obtain precise carrier details. Given below are some steps that will show you how to integrate an API such as numverify into your Python application to conduct a mobile carrier lookup.

Sign Up and Get the API Key

To start, go to the numverify website and sign up for a user account. After registering, log in to your account and go to the API section. From there, you can generate an API key which will serve as an authentication token, allowing you to access all of the features of the numverify API.

Install Required Packages

We will utilize the requests library in Python to manage API responses and perform HTTP requests. If the library is not yet installed, open the terminal or command prompt and execute the command mentioned below.

pip install requests

Writing Python Code

Next, we will write Python code that can interface with the Carrier Lookup API. Our plan is to develop a function, get_carrier_info, that requires your API key and a phone number as inputs. This function will create an API endpoint using the provided inputs, then send a GET request and extract the carrier information from the JSON response.

import requests

def get_carrier_info(phone_number, api_key):
    endpoint = f”{api_key}&number={phone_number}”
    response = requests.get(endpoint)
    data = response.json()
    return data.get(“carrier”, “”)

Make sure to substitute the placeholder ‘YOUR_API_KEY’ with the real API key that you acquired earlier.

Calling the API Function

Once you have defined the function, you can use it by inputting a phone number and then displaying the corresponding carrier information.

api_key = ‘YOUR_API_KEY’
phone_number = “+1234567890”

carrier_info = get_carrier_info(phone_number, api_key)
print(“Carrier:”, carrier_info)

After the search is complete, you will receive details about the carrier that is connected to the phone number you provided.


Method 2: Using Regular Expressions

Although Carrier Lookup APIs are very accurate, a simpler solution can be found by using regular expressions to extract carrier information in-house. Regular expressions are patterns that are used to match and manipulate strings. In this approach, we will investigate how to use regular expressions to carry out a numlookup. The steps shown below will show you how to find a carrier by phone number using this method.

Writing Python Code

You can use regular expressions to find particular patterns within strings. To extract information that resembles a phone number carrier, we will develop a function named extract_carrier_info. This function will take a phone number as input and use a regular expression pattern to locate and extract relevant carrier information.

import re

def extract_carrier_info(phone_number):
    carrier_pattern = re.compile(r”\b\d{3}-\d{3}-\d{4}\b”)  # Customize based on your country’s phone number format
    match =

    if match:
        return “Sample Carrier”  # Replace with actual carrier information
        return “Carrier information not found.”

If you want to focus on a particular type of phone number format, you can modify the pattern in the carrier_pattern variable. Simply adjust it according to the phone number format used in your country.

Calling the Function

Once you have defined the function, you can input a phone number as a sample and then print out the extracted carrier information.

phone_number = “123-456-7890”  # Replace with your phone number
carrier_info = extract_carrier_info(phone_number)
print(“Carrier:”, carrier_info)

If the phone number entered meets the designated format, you will be presented with details similar to those provided by the phone carrier. However, if the information is not found, you will receive a notification informing you of the same.
