If you have answered a call from an unknown number, please share the information about who called.
Find the phone number, check its ratings, read reviews from other users, and share your opinion.
It happens quite often that we receive calls from unknown numbers. You don't know if it's something important or just spam and persistent telemarketing. It's a waste of time.
Respect your number. Do not provide it where it is not absolutely necessary. In various contests, games, or when registering on untrusted websites, skip that field or come up with a random number.
On the whoiscalling.org website, you can directly check a phone number. Just enter the number in the search bar at the top of the page. You will be redirected to the appropriate subpage where all the information about the requested number will be available. Users can rate it on a 3-point scale. Additionally, they can add a review with information about who called them and for what purpose.
