Supreme Court has recently (2008 or 2009) declared that it is only fraud if it belongs to someone (so using an unbound number is fine) and you know that it does belong to someone. If you just typed in 062-15-2155 and you have no idea if it belongs to anyone then it's fine. If you saw someone's SSN card and copied the number on it then that's fraud. Still I personally would not use any documents with a fake SSN on them.
