This is a number from same people using 972-598-9069...if a call comes in without the 1 in front of the area code, they will surely call again with the same number but using the 1 before the area code.  Some numbers have to have the 1 in front of it so they assume it doesn't work without the 1.  It also works in reverse.  If a number comes in with a 1 & they can't get through, they will  call again but without the 1 in front of the area code.  When they have used up these numbers, they will get another burner phone & start calling people with a new number & it starts all over again.  I'm glad I have a call blocker that has 9,999 numbers to be inputted between good callers & bad callers.  I will block this number with & without a 1.
