Most receipts will only say you purchased a ticket since the tickets for Powerball, Mega, Lotto, etc. generally aren't actually scanned but rather just have the dollar amount entered into the register. The receipt won't have the numbers you chose on it . What you really need to do is sign the back of your ticket. That is the only proof you have that it's yours. You could also take a picture of the front and back of the ticket as extra evidence, but mostly just sign it and keep it in a safe place.
