What if you can’t find the owner of a phone number?
There are situations where the person with a phone number cannot be tracked down despite utilizing all the free options. This is due to various factors: the figure might be transitory, pre-paid or not entered into official databases. Also, other users prefer to have their information confidential and it is not accessible online.
In case you are unable to recognize the number, there are measures that you can apply to safeguard yourself. On the suspicion of a scam or harassment, file the number at 33700 or signal-spam. You can also block the phone number so that no further contact can be made. If you suspect fraud, call the telecommunications carrier involved with the number, which can give you further instructions or mark suspicious accounts.
These precautions are both safe and do not violate the laws of French privacy. Although this number may not be completely tracked down, these steps mitigate risk and will provide peace of mind.
