Where do you see that in the guide book? I had to assign a serial # to a couple of guns recently and called to talk with a specialist about it. She told me to pick any number that is not a duplicate in my books and carry on. I see no place in the guide book that states you need prior permission. I could be wrong and have been in the past.
