Receiving calls from unknown numbers can be a common occurrence, and it’s not always easy to decide whether or not to answer.

However, it’s natural to want to know who’s on the other end of the line before you pick up the phone, but identifying unknown callers can be a challenge. Luckily, there are several websites available that can help you determine the caller ID or owner name of an unknown phone number.

In this article, we’ll take a closer look at some of the most popular and reliable websites for identifying unknown phone numbers.

Whether you’re trying to avoid telemarketers or just curious about who’s calling you, these websites can be a valuable resource for anyone looking to uncover the identity of unknown callers.

Accordingly, let’s dive into our list of the best websites for finding phone number caller IDs and owner names.

Caller ID

Google it!

The first thing I like to do is to search for phone number on Google, Bing, Yandex search engines. In this example, I am searching for a landline number of McDonald’s in Germany.

Additionally, You can also search for the same phone number in different formats:

030 21234246
030 – 21234246
+49 30 21234246

To narrow down your search results, you can use the quotation marks to search for a specific string in a website. This will only show pages that contain those exact words or phrases



Of course, you won’t always be able to find the called ID of a phone number just by googling it especially if it was a mobile number but most of the time, this method works to find whether the phone number is a scam or it will show you to which company this number belongs to.



Truecaller is a great website to search for both landline and mobile phone numbers. They have a huge database of phone numbers.

However, it’s important to note that Truecaller collects and stores users’ phonebook information to improve caller identification, which can raise privacy concerns.

I recommend you use an Android virtual machine without contacts since using Truecaller on your personal smartphone can result in your contacts being uploaded to the Truecaller database.


Infobel is a global online directory that allows you to search for individuals, businesses, and public services. The directory is available in over 120 countries and contains contact information, including phone numbers, addresses, and emails.

That’s Them, Whitepage, ABC etc…

If you are looking to find the called ID of a US phone number, then check out websites like That’s Them, Whitepages, Advanced Background Check, Fast People Search etc…

These sites offer a comprehensive search for phone numbers, physical addresses, first and last names, and ages. With so many options available, finding the information you need has never been easier.

In this example, I have used That’s Them to search for the owner of this phone number and as you can see we’ve got a physical address, name, and an email address.
