The number (662) 255-3743 spells out "No Caller ID." The "66" spells NO, the "225537" spells CALLER, and "43" spells out ID on the keypad on your phone. So if you get a prank call with No Caller ID and copy and paste it in your keypad, it will always type out this number because it's just converting the letters to numbers. You can test this out by using someone's phone (dial *67 before typing out your phone number in the keypad show it'll show up as No Caller ID) to call your phone. When you copy and paste No Caller ID in the keypad, this number will show up every time.
