You need to set up an account with the California DOJ. They will assign you a dealer number. You will need to contact the CA dealer and get their number. Once you have their number you need to log into your account and enter your number and the FFL # in CA's # to obtain a shipping authorization #. I always make a copy for the CA dealer and keep a copy for myself. Sounds like alot but its really pretty easy once you get established with DOJ.
