The EPF Certificate was an award in Club Penguin. All players could obtain it by either unlocking it with the code card included in the case of Club Penguin: Elite Penguin Force, or by transferring coins from said game to online Club Penguin. Owning this certificate granted access to the Command Room from the cabinet in the PSA Headquarters, until both HQs were removed.
