How to find out who a phone number belongs to: the most trusted apps and websites. Receive a call on your mobile phone from a phone number that you have not saved in the phone book, do you accept? I’m afraid most of you will answer this question negatively, after all, a good portion of mobile phone users reject these calls to avoid SPAM (advertising calls). Others make a slightly less drastic decision: they look for the phone number on Google to find out who it belongs to.

The problem is that this type of phone calls (SPAM) has also caused the growth of services, web pages, and apps that promise to make you find out who a phone number belongs to, but not everyone manages to keep what they promise. Therefore, in this guide, we have made a selection of all those most reliable websites, applications, and services to verify who owns a phone number.

How to find out who a phone number belongs to: the most trusted apps and websites

Google phone

If you’re lucky enough to have a phone compatible with the Google Phone app, chances are you won’t even need to use a website to identify phone numbers. The big G has a huge database of phone numbers, in which users have marked them as SPAM, so that, upon receiving a call, the application itself will notify us whether or not it is a call from a malicious source.

But that is not all. Thanks to the fact that the application is also able to associate the phone numbers of the calls with those belonging to the companies, the call reception screen will show the name of the company itself if available.

Yellow pages and White pages

But if Google doesn’t tell us who a phone number belongs to, we can use some databases like yellow pages or white pages to find out who a specific phone number is. Since we will not initially know if it is an individual or a company, we can go to the yellow pages site to try to find out who that phone number is.

If we can’t find it there, then we can run the same method on the blank page web page and check if that phone number matches one in particular.
