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

The problem is that this type of phone call (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 all of them manage to deliver what they promise. Therefore, in this guide we have made a selection of all of those more reliable websites, applications and services to check 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 are lucky enough to have a compatible phone 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 malevolent source.

But that is not all. Thanks to the fact that the application is also capable of associate the telephone numbers of the calls with those belonging to companies, the call receiving screen will show the company name 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 belongs to. Since we won't initially know if it's an individual or a company, we can go to the yellow pages site to try and find out whose phone number is.

If we can't find it there, then we can run the same method on the white pages webpage and check if that phone number matches a particular one.

Whoscall - Caller ID + Block

Now, you no longer have to guess the number when you receive an unknown call or SMS on your Android phone. Just use Whoscall - Caller ID + Blocking to have full call control on your Android phone. The features of this app are available both online and offline, allowing for immediate identification of unknown numbers.

Furthermore, it is a constantly evolving service, as the list of telephone numbers is updated every day, thanks to the participation of users.

It has a search engine that allows you to find any phone number and read the opinions of other users.

The best thing about this site is that it is not necessary to register to look up phone numbers, nor install anything, even if they have their own Android app, which allows you to block SPAM calls as well know who a phone number belongs to.
