How do you trace who owns a mobile phone number?
Select country and paste the number and search. You may get the owners name and location. Sometimes, you may not.
There's no universal answer to this. It depends on the country, on the type of phone contract the person has (pay-as-you-go can't be traced back to an owner) and on their own willingness to identify themselves.
Could you give us some context regarding where you are and why you are asking the question? We may be able to help, but we'll need the info. Thanks.
I am in the UK and I have a feeling that I am being scammed..
You can use the trucaller app, available for Android and iPhone.
