How to Fetch Caller ID Information Using Python
Users sign up on websites and provide fake numbers which causes hassle to businesses. By building a caller ID information fetcher, businesses can verify if the customer’s phone number is valid or not.
They can use this data to personalize their communication, generate leads, optimize their services, and target SMS campaigns according to the customer’s geographical location. Explore how you can fetch all this information using the numverify API and Python’srequestsmodule.
Installing the requests Module
Therequestsmodule makes it simple to make HTTP requests and returns a response object that contains data such as encoding and status. You can use it tocreate a news application, website status checker,currency converter, stock market monitor bot, and many more practical applications.
To install therequestsmodule, open the terminal and run the following command:

How to Use the numverify API in Your Python Code
You can find the entire source code for fetching caller ID information using Python in thisGitHub repository.
Begin by importing therequestsmodule. Ask the user to enter a valid number and store the API key you generated earlier in theapivariable. Set the URL along with theapiandnumberparameters.
Send an HTTP GET request to numverify’s server and store the response you received. Parse the content you received and save it as a JSON object.
If the JSON object’svalidproperty isTrue, the number is valid, and you can display the rest of the contents fetched by the program. The JSON response contains the number, its local format, its international format, the country prefix, the country code, the country name, the location, the carrier, and the line type. Access all of this information one by one and display it on the screen.
If the API key or the number is incorrect, or the network is down, the program will fail to fetch the data. In this case, display the following message to the user.
Put all the codes together, and you are ready to fetch the details of any phone number from 232 countries in the world.
The Output of Fetching the Caller ID Information Using Python
On running the program, it asks to enter a phone number. On entering a valid number, it fetches all the details of the phone number and displays it. Otherwise, it asks you to recheck and enter a valid number.
numverify API Alternatives
Apart from numverify, there are several other APIs you may explore for phone number validation and tracking. Some include Twilio, Nexmo, Truecaller, Vonage, and HLR lookup.
Twilio supports multiple channels of communication like SMS, voice, and video. There is extensive documentation with customer support in case of any queries. Nexmo provides SMS and voice messaging capabilities, has global coverage, and allows users to verify their phones using two-factor authentication. Truecaller offers spam-blocking features, a phone number search feature, and offers SDK for businesses to integrate into applications.
Twilio and Nexmo offer a cloud-based API platform covering multiple communication channels. In contrast, Truecaller focuses on Caller ID features and Vonage offers comprehensive communication APIs with a wider range of pricing plans.
Enhancing Your Application
it’s possible to further enhance your application by transferring your call logs to a personal computer and using Selenium to automate the caller ID fetching process. If you don’t want the hassle, you can install applications that will do this for you if you do not mind sharing your personal data.
If you’re looking for a quality caller ID and spam blocking service but don’t want to use Truecaller, check out these replacements.
