Do i need a certified scuba id in order to get a scuba tank filled ? - scuba fill calculator

I thought buying a bottle for my scuba tank paintball HP and my father and I had to do it, but then someone said, you need a certified diver, identification, complete a diving course on how you buy and what not? Anyone who knows anything about this or maybe if someone knows where they have no identity?
