Open Source Intelligence: How to find anyone's phone number

Google Dorks

Sometimes people link their phone number and email to their Facebook profile, so typing it into a Facebook search may display the profile. Another option is to look up a database of user-provided phone numbers, such as whocalledme.com. This database is not limited to the United States, but European numbers can be looked up as well.

Also, for those who want something like this but on a mobile device, there are several applications: privacystar.com, getcontact.com and everycaller.com.

There are many reverse phone lookup services, and they are usually country or region specific, so find the one that fits your needs.

Android emulators

Many Android apps will work fine on the emulator, but some apps may not work as expected. However, running apps on the emulator has many advantages: your real account or phone number will be safe because you don't have to install faulty apps on your phone, and you can easily spoof GPS coordinates.

Save the number in your phone and then check the list of Viber or WhatsApp contacts. These services allow adding photos, biographies and names of the owner and extracting this information just by knowing the phone number.
