I got a phone call from a weird number, it was a call from +1(-1), what should I do about it?
I just got a call from a very weird number. On my phone it displays "+1 (1) (5 )" and "USA" below.
Next I tried to call the number again, but a default voice from my phone company told me that the number was invalid. What could this be?
So what is this caller id?
Well the called id is definitely invalid since anyone with a call center can change the caller id of the call this is probably one of the two following things: The caller set it that way and your service provider identified the call from +1(1) which is the USA area code and that's why it says USA. Your service provider noticed that it is a number with no id but it did come from a call center in the US and attached the "+1 (1) (5 )" for their own reasons (Carriers do this to try and inform the user with as much info as possible). So what is this? A famous marketing technique to detect valid phone numbers is to call them not using any caller id and check if they answer which would indicate they are valid. Since this is an automated system there is no voice on the other side.
