Calls from unknown numbers can be dangerous for many reasons. On the other side there may be, for example, a fraudster trying to extort sensitive information from us. The Office of Electronic Communications (UKE) has also been warning for years against incoming calls from international numbers – usually registered outside Europe – which may prove to be very expensive.
Experts warn against unknown phone numbers. They indicate what to pay attention to
UKE warns that fraud attempts often involve making short calls from international numbers in the hope that the recipient will decide to call back out of habit. “Unaware of the trick, users often call back to this number and are charged by the operators for international calls,” officials point out. These types of connections are often prolonged, for example by playing a false disconnection tone.
So there are recommendations to be careful with surprisingly long numbers. Polish numbers consist of nine or 11 digits – in the latter case they should include the area code “+48”. Foreign ones are often longer. They can be up to 14 digits long. Our vigilance should be aroused, among others, by calls from numbers consisting of 10 digits.
It is also worth keeping the area codes in mind and making sure that the incoming call is local. UKE and Internet users recommend paying special attention to numbers starting with the digits: “225”, “242”, “247”, “258”, “261”, “503”, “535”, “675”, “676”, “690”, “703”, or “734”.
Calls from an unknown number. How to defend yourself against fraudsters?
If you have any doubts, it is worth looking up the number on the Internet. Currently, there are many portals available on the Internet, whose users warn against dangerous connections. These include: unknown-numer.pl and numerytelefony.com.
However, if we receive a call from a strange number, it is worth remembering that you should not provide unknown callers with personal data, PESEL number, ID card number and series, or bank account login details. Fraudsters often try to obtain this type of sensitive information by posing as representatives of banks or other financial institutions.
