But what is “Whois data”? Is it available for any website, or are there any limitations? Stick around if you want to know everything about it!

What is Whois Data?

As of early 2020, approximately 1,2 billion websites were operating online. And there’s a Whois data for each one. But what is it, exactly?

Each site has an owner (an individual, a business, or an organization) behind it. When someone wants to create a new site, he or she must provide personal and legal information to independent registrars.

Let’s take a moment to clarify. The term “registrar” refers to accredited organizations that manage domain names and operate in accordance with domain guidelines. At the same time, a person (or a company) that wants to reserve a domain name is called a “registrant.”

A registrant is responsible for providing the correct data about him or herself. That includes name, legal address, telephone number, email, as well as other personal and technical information. That info essentially identifies ownership over the website.

And now, take all that info about the registrant and registrar, add data about the domain’s status and website history.

Why You Should Check Whois Data for Website

Why is it important to determine the domain’s owner? There are many reasons why you should. Let’s name a few.

You can verify information about a website

Let’s say that you want to buy a domain name. Should you go in blindly without checking who actually owns it? Of course not. Find out who is the registrant of the domain. That way, you can make sure that you’re negotiating with an actual owner instead of a scammer.

Find contact information

Have an exciting business offer or seeking partnership? You can check Whois data for the website to discover the owner’s email address, telephone number, and other contact data.

Check up the data validity of your website

You may also miss important offers if your contact information is incorrect. That’s why it’s crucial to use lookup tools to verify the validity of your website’s Whois data.

Ensure that privacy protection measures are in effect

Whois tools can help you confirm that the privacy protection options for your domain are working correctly.

Learn about the portal’s history

Whois services allow you to find historical data related to the website in question. You can find a lot of curious things about a domain by checking that information. And it also can help you avoid online scams.

Avoid scammers and phishing websites

Imagine that you’ve found an interesting product form a peculiar online shop. Don’t empty your wallet without a second thought! Instead, lookup website owner to verify the shop’s authenticity first. Did you know that over 1.4 million phishing websites are created every month? It’s not hard to fall into a trap. Want to avoid scam and fraudulent websites? Then you must learn how to check Whois data for websites.

Whois Privacy Protection

Sometimes you won’t be able to find the website owner easily. Why? Because many registrars offer Whois privacy protection. It’s a service designed to cover the registrant’s information from the public eye.

If you’re trying to look up website owner but get information about the registrar instead – you’re probably encountering a protected domain.

The privacy applies only to the general populace, though. Privacy protection doesn’t relieve registrars from an obligation to share Whois data with authorities upon official request.


Whois data is an integral part of the World Wide Web. Now that you know what this term entails, you should understand how crucial it can be to lookup website owner. And, as you see, checking Whois data for website isn’t brain surgery. Remember that a couple of clicks could save you a lot of trouble in the future.
