I don't think there is a current code. By the way, I got my Lady Vypr and it is really nice. No scratches, the LED is barely noticeable (a blacklight purple that I'm sure it will look nice in the dark) and the vapor production is more consistent than my KR808
batteries. The switch is a tiny push button and the unit is only about the length of my hand with the 510natty and cart. I have very tiny hands (my 12 year old's hands are the same size as mine) so I could stealth vape without switching the battery around. I'm loving it
